The Best Switch Films for a Mechanical Keyboard
Researched by Johnny Alto · last updated July 29, 2026
Short answer: The best switch films for a mechanical keyboard are the Durock 0.15mm HTV+PC Switch Films (120 pcs). For films you can actually buy on Amazon today, the Durock 0.15mm HTV+PC double-layer films are the sensible universal pick: the thin polycarbonate layer tightens housing tolerances to cut stem wobble while the soft HTV layer adds a touch of dampening, and 120 pieces covers a full board with spares. The main things to weigh are match material and thickness to the housing, films only help loose housings., fit is about housing shape, not pin count, and pair with a lube job.
Durock 0.15mm HTV+PC Switch Films (120 pcs)
For films you can actually buy on Amazon today, the Durock 0.15mm HTV+PC double-layer films are the sensible universal pick: the thin polycarbonate layer tightens housing tolerances to cut stem wobble while the soft HTV layer adds a touch of dampening, and 120 pieces covers a full board with spares. They fit the broad run of MX-style switches (Cherry, Gateron, JWK, Kailh). The honest limits: films are a marginal mod, and enthusiasts generally rate boutique films (Deskeys, TX) as fitting a wider range of housings and feeling more premium, films only help if your switches have loose housings in the first place, and hand-filming 60 to 100-plus switches is genuinely tedious for a subtle change.

Representative image.Switch films are thin shims placed between the two halves of a switch housing to kill housing wobble and tighten a sloppy fit, which can make typing sound a bit deeper and more solid. They matter for people building or modding a board who already have their switches apart, ideally while lubing, and notice loose rattly housings. If your switches already snap together tightly, films do little and can even cause problems, so this is a mod for loose-housing switches, not a universal upgrade. Here is the buyable pick, the enthusiast favorites, and the honest fit caveats.
How do the best options for switch films for a mechanical keyboard compare?
| Pick | Product | Why it makes the list |
|---|---|---|
| Top pick | Durock 0.15mm HTV+PC Switch Films (120 pcs) | For films you can actually buy on Amazon today, the Durock 0.15mm HTV+PC double-layer films are the sensible universal pick: the thin polycarbonate layer tightens housing tolerances to cut stem wobble while the soft HTV layer adds a touch of dampening, and 120 pieces covers a full board with spares. |
| Best-fitting (vendor-direct) | Deskeys DK Switch Films (0.3mm compressible) | Widely considered the best-fitting films because the thick, compressible material molds to almost any housing gap, large or small, and adds a softer feel. They sell through hobby vendors (deskeys.com, KBDfans, CannonKeys), not a reliable Amazon listing. |
| Tunable thickness (vendor-direct) | TX Switch Films (0.125mm / 0.15mm PC) | Two thicknesses let you match the film to your housing (0.15mm for normal/loose, 0.125mm for already-tight). Stiff PC films are fiddlier to seat than compressible rubber, and they are hobby-vendor-only, not on Amazon. |
| Compressible foam option | ZugGear 0.3mm Foam Switch Films (120 pcs) | A thick, compressible foam film that self-fits loose or tight housings and adds thock, available on Amazon. At 0.3mm it can over-tighten some housings and dampen crispness. |
What should you look for in switch films for a mechanical keyboard?
A few things separate a good switch films for a mechanical keyboard from a frustrating one: match material and thickness to the housing, films only help loose housings., fit is about housing shape, not pin count, and pair with a lube job. Weigh these before you buy.
- Match material and thickness to the housing: 0.15mm PC (or PC+HTV) is the safe default, 0.125mm for very tight housings, 0.3mm compressible foam for loose or mixed housings.
- Films only help LOOSE housings. On tight switches they do little and can stop the housing fully closing, so test one or two before doing a whole board.
- Fit is about housing shape, not pin count: 3-pin vs 5-pin is irrelevant; nearly all films are cut for MX-style housings, and proprietary housings (Kailh Box) may not fit.
- Pair with a lube job: filming means opening every switch, so most people film while they lube rather than as a separate pass.
Films only fix a problem you might not have
Switch films are the most over-recommended mod in the hobby, so here is the honest framing: a film is a thin shim that goes between the top and bottom halves of a switch housing to remove the tiny gap that lets the housing wobble. If your switches have that gap, a film tightens them up and the sound gets a touch deeper and more solid. If your switches already snap together tightly, a film does essentially nothing, and a film that is too thick can actually prevent the housing from closing fully, which makes the switch feel like it bottoms out early or stops the leaf from seating. So the mod is conditional, not universal. The way to know is to open one switch, snap it back together, and feel for wobble; loose housings are film candidates, tight ones are not. Match the thickness to the gap (0.15mm PC is the safe default, thinner for tight housings, thick compressible foam for loose ones), and because filming means opening every single switch, everyone does it during a lube session rather than as its own tedious afternoon. It is a fine-tuning step for a subtle gain, not a transformation.
What are the best alternatives?
Deskeys DK Switch Films (0.3mm compressible)
Widely considered the best-fitting films because the thick, compressible material molds to almost any housing gap, large or small, and adds a softer feel. They sell through hobby vendors (deskeys.com, KBDfans, CannonKeys), not a reliable Amazon listing.
TX Switch Films (0.125mm / 0.15mm PC)
Two thicknesses let you match the film to your housing (0.15mm for normal/loose, 0.125mm for already-tight). Stiff PC films are fiddlier to seat than compressible rubber, and they are hobby-vendor-only, not on Amazon.
ZugGear 0.3mm Foam Switch Films (120 pcs)
A thick, compressible foam film that self-fits loose or tight housings and adds thock, available on Amazon. At 0.3mm it can over-tighten some housings and dampen crispness.
Check price on AmazonBottom line: the Durock 0.15mm HTV+PC films are the convenient, good-enough Amazon pick for tightening loose housings; the enthusiast-favorite Deskeys and TX films are better-fitting but vendor-only. Only bother if your housings are actually loose, and film while you lube. Pair it with our switch-lube and stabilizer guides.
