Hello, does anybody know what screw size would fit these slide switches (M1, M2, M3 etc)

 

Hello,

The size of the screws should be given in the datasheet of the switches.
It could me M2 or M3, depending on the overall size of the switch.
Keep in mind that some will be threaded and some not.

I have attached some datasheets to show.
The datasheets are downloaded from this page:

Yeah, what @bertus said. What makes you think that we have more information than you?

 

They aren't necessarily M anything. They may be UNC, UNF, etc.

 

It could actually be M2.5 also this is more common than M2, when M3 is just too big for something.

 

You can always expand the holes and use whatever nut and bolt that fits.

Thanks a lot, I had read datasheets but most of them show dimensions, and I was not sure that 2mm hole means definitely M2 screw for example. I don't know about screws and you happen to know.

Yes I have done that already but I thought "let's do it right"

 

They aren't necessarily M anything. They may be UNC, UNF, etc.

Actually this is why I asked, as more datasheets mention diameter only, I was not sure that 2mm corresponds to M2 screw necessarily although it is the logic thought. I will get some M2, M2.5, M3 with nuts and washers and will take it from there.

 

What does the spec sheet say?
I took some random slide switch that looks like yours and I believe the thread size is M3 x 0.6.
