Switch film usually looks like a small piece of plastic with rectangle cuts inside so it can be put in between the top and bottom housing of mechanical switches to make it tighter.

Besides plastic, switch films can be rubber, PLA plastic, foam, or polycarbonate plastic. Based on the sound effect you want to produce, you should choose the proper materials for your mechanical switch films.

You cannot complete the job without the right switch film on hand. Aside from a big number of different materials, there are also many switch film brands out there. To save you time, we will talk about switch films and their brands for you to pick from near the end of this article.

Usually, you should buy more switch films than the number of mechanical switches that you want to film. That is for when things go wrong so you need a backup to redo. Just buy as many extras as you feel like you will need.

There are metallic and plastic switch openers in the market. Of course, a plastic one will be way cheaper but we recommend you invest a little bit more to switch openers made of aluminum or steel (or at least a very good plastic one).

The reason is that metal is much stronger and way more durable to open the mechanical switches. A strong and stable switch opener can assist you super well without tiring your fingers or breaking your expensive switches.

Just remind you a little bit. Sometimes, the number of switches you need to film does not stop at 10. It can be 50 or more in fact.

Tweezers

There is a high chance you will drop or break the switch films if handling them with your fingers only. That is why we think a good tweezer is necessary to do the job meticulously. It does not only reduce the dropping rate but also makes the keyboard switch film process faster and easier.

You could use a tweezer that’s already there in your house. We think a tweezer with a sharp point will be the most suitable one for the job so grab it if you can.

Lubing Equipment (Optional)

Well, if you have already opened the mechanical switches, why don’t use this opportunity to lube them? For the lubing additional stage, you will need a small lubing tube like the one in the picture and things are mostly done.

We recommend Krytox 205 as it is a good buddy for the lubing job.

Steps to Filming Switches

For those who want to film switches on their mechanical keyboard, a keycap puller will be helpful. First, pull out the keycap with the keycap puller. Second, if you need to desolder the switches, use a desoldering gun. Then, use the keycap puller one more time to take out the switches.

If you don’t have the keycap puller, this video below will show you the way, so you don’t need to place a completely new order just for a mere keycap puller. Or, you can read this "How to remove keycap without tool" guide if your learning type is reading.

Now, it’s time to dismantle the mechanical switches for a switch film. In this stage, you should organize the parts of your opening switches in order not to make a mess on your working table.

Here is how you open them with a switch opener. First, place the mechanical switch inside the switch opener and make sure the switch tabs align with the corresponding bars.

After that, you press on the cross-shaped stem until it creates a ‘click’ sound and opens. Just like in the video below. Note that you should take a picture of the direction of the top and bottom housing so you have a reference later on.

In the last step, divide the top, bottom, spring, and stem into different places so you won’t lose anything. Trust us. You don’t want to.

How to film switches cannot be done without this step. First, you need to recognize the difference between switch films for LED effect and switch films not for LED. That is because switch films for LED effect will have one small rectangle cut and one large square cut that should be put in the right direction.

To switch films with only one large cut, you don’t need to care about the direction. Just use the tweezer to place it on top of the bottom housing.

Regarding LED effect switch films, the small area will be placed in the position where LED lights will go through while the large area will align with the edge line of the bottom housing.

If you put the switch films in the right way, there will be no extra film sticking out when closing the switch nor crunchy sound when pressing the key.

Reassemble the Switch

First, put the spring on top of the bottom housing (look at the picture). Then, place the stem on top of the spring with its leg facing the metal leaf. Hold the top housing and place it in the correct direction like the picture you have taken when opening it. Or, you can use an untouched mechanical switch for a reference.

Different Types of Switch Wobble

Stem Wobble

You switch stem moves a little bit due to there being space between the top housing and the stem, and this wobble is normal.

Top Housing Wobble

When the switch’s top housing is not stable and moves around, the result is inconsistent switch typing and an annoying sound. Fortunately, you can reduce the unwanted effect with switch films.

Bottom Housing Wobble

Normally, when the top housing wiggles, it will drag the bottom housing waggles together. The degree of wobble varies on the switch type and brand but overall, it can be reduced thanks to the switch film attaching between the top and bottom housing.

What Films Do To Wobble

Sometimes, due to the design or poor production, there is still space between the top and bottom housing. Therefore, when pressing the switch, they will create a wobble and weird sounds.

By putting a thin layer as a switch film between the two housings, the space is reduced and the housings fit tighter. Therefore, no more wobble is guaranteed as well as unwanted sounds.
