Conveyor Controls and Connections

The control circuit for a conveyor, like for an other piece of motorized equipment, will depend on what one's trying to do and protect against and what type of starter/contactor one uses.

First, about your switches: wire the inlet terminal of the one of the switches' normally-closed (NC) or normally-open-held-closed (NOHC) contacts to the control-voltage source of the motor's MCC (motor control centre) module. I'm assuming that you're using an AC induction motor, by the way. Connect the other switches' NC or NOHC contacts in series with the first switch's. That way, you'll have a chain of contacts, any one of which will stop the motor if that contact opens.

Then, connect the outlet of your last switch in the chain to the first terminal whatever control circuit you have in your MCC. That control circuit may contain auto/manual swicthes, remote/local switches, on and off pushbuttons or switches, emergency-stop pushbuttons, motor overcurrent and overload protection, etc.. The control circuit will be designed to control and protect the motor is accordance with your specific application.

Hope this helps. Cheers!
