Ultra Float Switch by Ultra Safety Safety Systems - Senior Float Switch 12 Volt

Automatic Bilge Pump Switching with Built-In High Water Level Alarm Feature

This pump switch is in the off postion when the float is at the bottom of its housing. When the magnetic float rises 1-1⁄4" the switch turns on the pump. If the pump cannot remove the water as fast as it is coming in and the float rises another 1" then the alarm circuit is activated. The alarm circuit is normally open (and can carry a current limited to 100mA max). Switches with a normally closed alarm circuit (used on Bertram boats) can be special ordered.
