[autobonifica]

in my oven, i have a 2 wires coming into one leg of the contactor. The wire goes to a switch then directly to the power supply of my controller. from there it is jumpered to the output supply relay(internal in the controller.) that runs directly into the contactor to supply voltage to close the contacts. then the other side goes directly to the ground.

i hope this helps you some...if not...maybe it will someone else
