I am looking for a momentary push button for use on a PCB. I just want a very simple button that leaves the connection open when not pressed, and closes the connection when pressed. So a SPST switch seems to be the way to go.
But when I look around for a SPST switch on digikey, I quickly get confused about how to actually implement them. I feel that an SPST switch should have only two terminals. Why are there some with any more than that?
For example, this little button would be perfect for my needs, except for that fact that it has SIX terminals! The datasheet doesn't explain which pin is what, or at least not in a way that I can understand.
Why can't I have just a simple little on-off button?
