Hello
I am relatively new to PCB design and am currently designing a simple circuit for a bike light. The LED's will be controlled by a PIC12 which will have an input from some kind of button. My immediate idea was to use a regular tactile switch for the button, but from looking at a range of different electronics it seems to me that some kind of a silicone key (similar to those used here https://learn.sparkfun.com/tutorials/bu ... okup-guide also see img below) is more widely used. I have been unsuccessful in my attempt to find out how to do these. So my question is then, how do I integrate these into my PCB design? Can I do the contact areas with regular open copper pads, or does it need to be covered by gold or similar? Also, how would I draw the footprint (I'm using Eagle)?
Thanks in advance
