Couldn't you use a toggle/push-button switch if it was momentary (spring-loaded)? (i.e. "push-on, push-off")

This contact will be using an enable wire from the board and another wire that is a ground. I think a flip flop MAY be the way to go. I was also wondering if there is a push button switch that has 2 spst contacts?
