hi,
I really facing difficulties creating a library for this component. can someone help please?
here is a link to the datasheet https://files.elv.com/Assets/Produkte/2/243/24380/Downloads/24380_TDW_data.pdf
its a triangle metal dome switch
thanks

Leroi,
I found this picture of a PCB footprint for a similar switch:
Unfortunately, a lot of the detail is obscured by the switch. The concept seems somewhat simple. One leg has a plated through hole to make contact with the switch (the site says not to solder the leg in the hole, just bend it over loosely to hold it in place - apparently soldering will change the click and possibly cause earlier failure). The center metal pad is the other contact. When the switch is pressed, the through hole and the center pad are connected.
The print quality of your attached diagram is difficult to read, but with parts in hand, you might be able to figure out the location to the two holes and the center pad location. As far as I can tell, you could do a plated through hole on both legs (I would make these a little tight, i.e. not too large, to keep things in place.
Hopefully this helps.

hi thanks for the reply.
This will be of course helpful. So basically the second leg is just for stability and plays no role.
I also found this library(dome-key.lib) but am not sure if this would be help. I though of using the inner circle as one contact the outer as the second.so the legs will just be there for mechanical stability on the pcb. I am not sure if this can as well work.
