Hi,
I have a question for all those experienced people over here

My jukebox application with which the coin mech should work is waiting for a circuit to get closed. Let's say it gives me 2 wires and when I stick them together, a credit is added. Now the coin mech should take over de circuit-closing but I do not really know how, since there's only one coin output on the mech. So I can stick one wire to the mech, but where should I stick the second in order to close the circuit?
Anybody familiar with this?
Thanks,
Marcel
