What Makes a Keyboard Switch Sound Thocky?

With mechanical keyboards, the word thocky is often used to describe a deep, full and relatively low-pitched sound.

But what actually makes a keyboard switch sound thocky?

Does it come from the material, the stem, the spring, lube or simply the keyboard in which you install the switch?

The answer is: all of these factors can have an influence.

A switch can sound relatively deep by itself, but the final sound is strongly determined by the combination of switch, keycaps, plate, case, mounting style, foam and even the surface the keyboard sits on.

Quick explanation

A thocky switch usually sounds deeper and less sharp. This can be influenced by housing materials, stem design, bottom-out contact, spring, factory lube and the overall construction of the switch. But a switch alone does not automatically make a keyboard thocky: keycaps, plate, case and mounting style play at least as large a role.

1. What does thocky mean?

Thocky is not an official technical specification.

It is an informal term used within the mechanical keyboard community for a sound often described as:

• deep;
• full;
• low-pitched;
• rounded;
• less sharp or metallic.

The opposite is often described as clacky, high-pitched or sharp.

2. Does thocky mean the same thing to everyone?

No.

Thocky is subjective.

What one person calls a deep thock may sound more creamy, marbly or poppy to someone else.

It is therefore better to think of thocky as a general sound direction rather than an exact category.

3. Can a switch itself be thocky?

A switch can have characteristics that make it sound relatively deep.

But the sound you hear when you actually type is created by multiple components at the same time.

The same switch can sound completely different in two keyboards.

4. Which parts of a switch affect sound?

Important parts include:

• upper housing;
• bottom housing;
• stem;
• stem pole;
• spring;
• factory lube;
• internal tolerances.

5. Does housing material affect thock?

Yes, but material alone does not perfectly predict sound.

Common materials include:

• nylon;
• polycarbonate;
• POM;
• different proprietary blends.

The shape, thickness and construction of the housing are at least as important as the material itself.

6. Does nylon automatically sound thocky?

No.

Nylon housings are often associated with a softer or deeper sound, but not every nylon switch sounds the same.

A thin nylon housing can, for example, resonate differently from a thicker housing with different internal geometry.

7. Does polycarbonate automatically sound clacky?

No.

Polycarbonate is regularly associated with a brighter or sharper sound, but switch design and keyboard construction can change that significantly.

8. What does POM do to the sound?

POM is widely used for stems and sometimes for housings.

The material has a smooth surface and can contribute to a certain sound and feel, but POM does not automatically mean that a switch sounds thocky.

The overall switch design remains more important than a single material name.

9. Does stem material affect the sound?

Yes.

The stem moves through the housing and makes contact during bottom-out and return.

Therefore, differences in:

• material;
• stem length;
• pole design;
• wall thickness;
• tolerances

can change the sound.

10. What is bottom-out sound?

Bottom-out sound is the sound created when you fully press the switch and the moving components reach their lower stop.

This is often one of the most noticeable sounds of a mechanical switch.

A deep bottom-out sound strongly contributes to what people experience as thocky.

11. What is top-out sound?

Top-out sound is created when the stem returns upward after release and reaches its upper stop.

A keyboard therefore does not have just one switch sound, but at least:

• bottom-out;
• top-out;
• spring noise;
• possible tactile or click mechanisms.

12. Why does a switch sound different when pressed and released?

Because different components make contact at each moment.

During bottom-out, energy is transferred toward the bottom of the switch and the keyboard.

During top-out, the stem instead contacts the upper housing.

A switch can therefore have a deep bottom-out but a higher-pitched top-out.

13. Do long-pole switches affect sound?

Yes.

A long-pole stem has a longer central stem pole.

In many long-pole designs, this pole contacts the bottom housing earlier.

This can create a more distinct, harder or more pronounced bottom-out sound.

14. Are long-pole switches automatically thocky?

No.

Long-pole switches are often described as:

• poppy;
• marbly;
• deep;
• hard-bottoming;
• clacky.

Which direction the sound takes depends on housing, pole material, length, keycaps and keyboard construction.

15. Can a shorter-pole switch sound deeper?

Yes.

A traditional stem that bottoms out on other parts of the housing can produce a softer or deeper sound than a hard pole-to-housing impact.

That is why long-pole does not automatically mean deep or thocky.

16. Does spring weight affect sound?

Yes, but usually indirectly.

A heavier spring can push the stem upward with more force.

This can affect the top-out sound.

A heavier switch can also make you type differently and bottom out harder or softer.

17. Can a light switch also sound thocky?

Yes.

Switch weight and sound are different characteristics.

A light 40–45gf switch can sound deep, while a heavy 60–70gf switch can sound bright.

18. Does spring ping affect thock?

Yes.

Spring ping is a metallic resonance sound from the spring.

If it is clearly audible, an otherwise deep switch can still sound sharper or messier.

19. What is spring crunch?

Spring crunch is a scraping or crunchy sound that can occur when the spring twists or moves against components during pressing and release.

This can also reduce the clean, deep character of a switch.

20. Does lube help make a switch thocky?

Lubrication can change the sound.

Lube can, for example:

• reduce scratch;
• reduce spring noise;
• dampen contact sounds;
• make the switch sound smoother.

This can make the sound fuller or less sharp.

21. Does more lube automatically mean more thock?

No.

Too much lube can make a switch feel or sound:

• slow;
• mushy;
• muted;
• inconsistent.

The goal is usually a thin, even amount.

22. Do factory-lubed switches often sound deeper?

They can sound smoother and cleaner than completely dry switches.

But factory lube varies greatly between manufacturers and models.

Therefore, “factory lubed” alone does not tell you whether a switch will sound thocky.

23. Do switch films affect sound?

They can.

Switch films are placed between the upper and bottom housing to reduce looseness.

On switches with loose housings, this can:

• reduce housing wobble;
• change resonance;
• make the sound tighter.

The effect can be very small on modern switches with already tight housings.

24. Does stem wobble affect sound?

Indirectly, yes.

More play can create additional small contact noises.

A tighter switch design can therefore sound cleaner, although extremely tight tolerances can also affect feel.

25. Are linear switches the most thocky?

Not automatically.

Linear switches do not have a tactile bump or click mechanism, so you mainly hear bottom-out, top-out and spring.

This makes them popular with people who want a clean and deep sound.

But tactile switches can sound just as deep.

26. Can tactile switches sound thocky?

Yes.

Tactile switches add a tactile bump, but can still have a deep bottom-out and top-out.

The tactile leaf and bump can, however, add extra sound.

27. Can clicky switches sound thocky?

They can have a deep base sound, but the click mechanism remains prominent.

With clicky switches, for example, you hear a click jacket or click bar on top of the other switch sounds.

That is why they are less often described as purely thocky.

28. Do keycaps make more difference than the switch?

Sometimes, yes.

Keycaps have a huge influence on the final sound.

Important factors are:

• material;
• thickness;
• height;
• profile;
• internal volume.

29. Do thick PBT keycaps sound deeper?

Thick PBT keycaps are often associated with a fuller and less sharp sound.

But this is not a fixed rule either.

Profile, construction and the keyboard also play a major role.

30. Does keycap profile affect thock?

Yes.

Taller keycaps often have more internal air volume and can resonate differently from low-profile keycaps.

Profiles such as SA, MT3, Cherry, OEM and XDA can therefore all sound different with the same switch.

31. What influence does the plate have?

The plate is an important part of the sound.

Common materials include:

• aluminum;
• steel;
• brass;
• polycarbonate;
• POM;
• FR4.

Stiffer plates are often perceived as brighter, while softer or more flexible plates can sometimes give a warmer or deeper character.

But the overall construction remains decisive.

32. Does the keyboard case affect sound?

Very much.

The case forms a resonant chamber around the PCB and plate.

Factors such as:

• aluminum vs plastic;
• case volume;
• wall thickness;
• internal cavities;
• weight;
• mounting style

can strongly change the sound.

33. What does foam do to thock?

Foam absorbs and changes resonance.

Depending on placement, foam can:

• reduce hollow sound;
• reduce case resonance;
• make the sound cleaner;
• dampen certain frequencies.

However, more foam does not automatically mean more thock.

34. Can too much foam sound bad?

Yes.

With a lot of damping, a keyboard can also start to sound very flat or dead.

Some users actually prefer more natural case resonance.

35. Does mounting style affect sound?

Yes.

Gasket mount, tray mount, top mount and other mounting styles transfer vibrations to the case in different ways.

This affects both feel and sound.

36. Can a desk mat make your keyboard sound deeper?

Yes.

A soft desk mat absorbs some of the vibrations transferred through the bottom of the keyboard into the desk.

As a result, the same keyboard can sound sharper on a hard table than on a thick desk mat.

37. Does how hard you type matter?

Very much.

Someone who heavily bottoms out every key will make the same switch sound different from someone who types lightly.

Typing style affects:

• volume;
• bottom-out impact;
• resonance;
• how dominant top-out sounds.

38. Can you identify a thocky switch from specifications?

Not reliably from one specification.

Specifications such as:

• POM stem;
• nylon housing;
• long-pole;
• factory lubed

can provide hints, but they do not guarantee a specific sound.

39. Is a sound test reliable?

Sound tests are useful, but only as a reference.

The recording is affected by:

• microphone;
• microphone position;
• room;
• audio processing;
• keyboard;
• keycaps;
• desk mat.

The same switch can therefore sound different in your own setup.

40. What is more important: the switch or the keyboard?

Both are important, but the keyboard as a whole has an enormous influence.

A relatively deep switch can still sound bright in a thin metal keyboard case.

An average-sounding switch can become much deeper in a well-damped build.

41. How do you make your keyboard sound thockier?

You can experiment with:

• switches with a deeper bottom-out;
• properly applied lube;
• thicker keycaps;
• a different plate;
• case foam;
• plate foam;
• gasket mounting;
• a desk mat;
• stabilizer tuning.

Preferably change one component at a time so you can hear what actually makes a difference.

42. Are stabilizers important for a thocky sound?

Yes, especially on larger keys such as:

• spacebar;
• Enter;
• Shift;
• Backspace.

Rattly stabilizers can make an otherwise beautiful deep build sound much less clean.

43. Why does the spacebar often sound different?

The spacebar is larger and contains much more internal air volume than a normal keycap.

As a result, it can sound:

• deeper;
• louder;
• more hollow;
• more resonant

than the rest of the keyboard.

44. What characteristics do people often look for in a thocky switch?

Many users look for a combination of:

• deep bottom-out;
• little spring ping;
• little scratch;
• tight housing;
• good factory lube;
• relatively soft or full top-out.

But there is no official “thocky switch” specification.

45. Thocky vs clacky

Characteristic	Thocky	Clacky
Pitch	Lower	Higher
Character	Deep / full	Bright / sharp
Impact	Rounded / heavy	Hard / direct
Preference	Subjective	Subjective

46. Is thocky better than clacky?

No.

It is entirely a matter of preference.

Some users want a deep and damped keyboard, while others prefer a bright clack or pop.

47. Common mistakes

• Thinking one material automatically makes a switch thocky.
• Thinking long-pole automatically means deep.
• Only looking at the switch while ignoring keycaps, plate and case.
• Using too much lube to make the sound deeper.
• Expecting a YouTube sound test to be the exact final result.
• Ignoring spring ping and stabilizer rattle.
• Treating thocky as if it were a technical specification.

Conclusion

A keyboard switch sounds thocky when the combination of materials, stem design, bottom-out, top-out, spring and lubrication produces a relatively deep and full sound.

But the switch is only one part of the final result.

Keycaps, plate, case, mounting style, foam, desk mat and even your typing style can make the same switch sound completely different.

That is why there is no single material or switch specification that automatically guarantees your keyboard will sound thocky.

If you are looking for a deeper sound, consider the complete keyboard build rather than only the switch name or material.
