The water pump in a RV is the week link.
Break the link between the motor and pressure switch, add a relay to buffer the current for the motor and get five to ten years from the pump.
Normally you can replace the item in two to three years cause of the micro switch in the head of the pump. The relay extended the life of the micro switch past the motor longevity. Switch one is the cut between the motor and control circuit. Closed switch two is the new connection to the relay.
The relay buffers the motor current and the switch provides the signal for the relay from the RV/caravan.
