njbuch - to control my board, how can this "remote switch" be controlled?
Sorry I didn't respond earlier, I assumed my account was already set to "watch" the forum for my creation. Anyway.....
The remote switch consists of two through hole pads with 0.1" spacing. One pad is a ground, the other pad is a connection to a pulled up enable pin that controls the output voltages. All you have to do is put the local switch in the on position, then anytime you pull the enable pin pad low the power will shut off.
The idea was that anyone could solder on there own mechanical switch between the two pads and turn the board off if it is in an enclosure.
But for your situation you need to know the enable pin is pulled up to 5V through a 10k resistor. So if your timer can pull that signal to ground it should work fine.
