Rule 37A Automatic SuperSwitch

Backed by a 5 Year Warranty, the non-mercury SuperSwitch™ is designed for the toughest applications.

The Rule Automatic SuperSwitch is a heavy-duty float switch that converts any bilge pump to automatic operation.

Heavy-duty contacts make this an ideal float switch for pumps drawing up to 20 Amps. It turns the pump on when the water level reaches 2" (51 mm) and turns the pump off when the water level drops to 3/4" (19 mm)

The design includes highly abrasion-resistant marine grade 14 AWG "blocked wire", a larger float for increased buoyancy, a removable base for easy servicing and a snap switch tested to over one million cycles.
