Questions and answers
I am trying to install this switch in my shower sump pump out. It operates through a 20 amp circuit breaker instead of direct wiring to a battery. It will not work although connected to the positive 12 volt wire. It will come on for one second when first switched on but will not work. Will this switch only work if connected directly to the battery?
