A few years ago, thinking I was being clever at the time, I bought a bunch of push-to-break push button switches, thinking then the logic in conjunction with using internal pull-up resistors would be more consistent. Now, logic aside I wonder if there are other issues I don't understand.
Are there pitfalls or trade-offs associated with push-to-break vs. push-to-make switches with regards to:
1) Loads on the internal pull-up resistors?
2) Idle current scenarios (e.g. one is always closed, the other always open)?
3) Un-initialized or pre-initialization pin concerns (switch connected to pin & ground)?
Thanks,
