Hello @Devan
I'd say using the C pin is optional. From the drawing you can see that the two C pins are just connected to each other internally. So to connect and switch a load you have two options:
- use both C pins: connect pin A and C to your power source and connect B and C to your load.
- do not use C pins: connect one wire of your power source to pin A, connect one wire of your load to pin B and use a direct connection from your power source to your load for the return wire.
