I can't use a toggle switch because the contact to
enable the scramble board needs to be momentary to
turn on the board and then a momentary contact to
switch off the board. 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?
Thanks.
