Simple problem, if I have a large button a user can put their hand on then I'm afraid they can put too much force and break the electrical button underneath.
If I make the external button bottom out before the electrical button (push button switch) how do I ensure the electrical button always activates?
All the push button switches I've looked at either have a very small window where they are guaranteed to activate but haven't physically bottomed (limited over travel) out or no window at all (no over travel), you just have to bottom them out.
Am I worried for nothing? Should I just assume the push button switches are robust enough to handle the force?
This is a low cost consumer device application, and I'm trying to avoid adding extra mechanical complexity or big expensive switches.
FYI this is a rewrite of what I asked in the electronics stack exchange.
