Hi I am haivng trouble working out how to do this.
12V battery on camper
12V water pump
Pull on push off isolation switch
Push on auto off button switch
4 Pole Relay

My idea is to use the pull on/ push off switch to simply isolate the + circuit close to the battery. thats easy

The other switch/button needs to be on a long lead so i can control the pump from a reasonable distance from the battery where the sink is.

I could run the battery + directly from the battery to the pump and use the isolation switch in this line to isolate the circuit.

Then run the Battery negative via the long lead and back to the pump.

Would this be ok? or should i use the relay? if so what is the best way to include the relay in the circuit.

Relay has 4 poles 30, 87, 85 and 86
