How can I wire these two switches together?
« on: February 11, 2009, 05:23:10 pm »
I'm trying to wire up my coin mech (standard switch) which is no problem but I also want to have the ability to press the coin return button to also apply credits.

Sounds easy enough BUT the spot I found to mount another micro switch for coin return button would require me to wire it such a way where the button is always pressed and only when you press the coin return button does it depress.

Can I wire these two buttons together? If so how?

Just use the NC instead of NO terminal on the switch in question.  Wire the two switches in parallel (commons together, NC on your fancy "reject for credit" switch with NO on your real coin switch).
