Hi,
I am looking for help wiring a 220 Volt single phase Contactor relay that has a single A1 Coil terminal to be used with 2 float switches to control a pump. I know how to connect a single switch to the relay but unsure how to add the second switch. Each switch can be Normally open or normally closed. Any help would be greatly appreciated.
Thank you in advance.

Hi,


Thank you for responding to my issue. I have attached a simple drawing of what I have for devices. Hopefully it will make it more clear. I need one micro switch to turn the pump on when activated and another switch to shut off the pump when the tank is full.
