Review on ESUPPORT 12V 30A Car Motor Heavy Duty Relay Socket Plug 4Pin Fuse Switch On/Off SPST Wire Harness Metal Pack of 2: Enhanced Automotive Power Control Components by Mac Quigley

I have an old Vetta with an aftermarket electric pump. I use it to switch. Low switching load of 0.1A and seems practical with 20A surges and 8A continuous current. Store in a cool place, not under the hood or near the exhaust. warm. Uses mechanical points. I would prefer solid state but it will last for years. I wouldn't use it with a 20A+ load. 10-15A OK
