Rule-A-Matic® Float Switch
Year after year, the Rule-A-Matic® has been the pump float switch of choice for boaters the world over. It turns the pump on when the water level reaches 2" (51mm) and then turns the pump off when the water level reaches 3/4" (19mm).
This latest design includes a removable base for easy cleaning and servicing plus highly abrasion-resistant, marine-grade "blocked" wire and a mercury-free snap switch tested to over one million cycles. It's designed for pumps drawing up to 14 amps, 12VDC.
Available with or without an in-line fuse holder. This product should be fused with the recommended fuse size for the pump to which it is connected.
