ok so I m not understanding in the diagram above..
.is that a 4PDT?? OR??

can you possibly put pin #'s o on the drawing?
IM SO SORRY BUT IM LOST
It’s not a 4PDT switch. It’s a DPDT switch. I’d get a center-off switch or a break-before make. It’d still be a DPDT switch, but just a special type.

The center pin is usually the common pin and goes to the motor. Each power supply goes to the pair of pins on each end.

I have 2 110v sensors that may call for the motor to activate at the same time. this is why a relay or relays are required to prevent BOTH from trying to power motor at the same time.
I see a couple of options. First option uses a single DPDT relay and allows only one sensor to power the motor at a time but gives priority to one sensor only (either sensor 1 or 2).
Second option uses 2 DPDT relays and gives priority to which ever sensor activates first.
