About Moniteurs de cale

Automatic Bilge Pump Float Switches

Bilge pump switches come in a variety of styles to suit any application. From a basic float style switch to field detector cells and air pressure switches, Defender offers just about any switch you may need.

How does a float switch work?

Water finds its way into every boat and the boat owner has to get it out. Bilge pumps take care of that chore but offer challenges of their own. Pumps can burn up when dry and will draw off all of your battery power if given the chance. Enter the automatic bilge pump switch and the bilge pump float switch is the most popular with its simple mechanics. The water gets high, the switch gets high, and signals the bilge pump to switch on. The float switch drops with the water level and cuts the pump off.

Can I DIY my bilge pump switch installation and wiring?

Sure! Defender's line of automatic bilge pump switches is offered complete with a shot of wire and specs to 12, 24, or 32-volt service. Several switches fit detachable mounting plates for easy installation. Other switches can be mounted at an angle. Spec out the location of your automatic bilge pump switch and check out all of the options Defender has to offer before you buy.

And the best automatic bilge pump switch is...

By far the most well know the switch is a marine float switch. Defender offers floats switches, protected float switches, and detachable float switches. Defender also offers switches that are time delayed, air-operated, sensor-operated, and prompted by changes in air pressure. Small spaces, oily bilges, and specialized wiring all play a part in which switch from Defender is the best.

Bilge Monitors & Manual Pump Switches

High water alarms, bilge alarms and gauges, switches, and monitors for control panels are offered to set your mind at ease. Kits from Defender enable boat owners to DIY this special safety feature. A high water alarm is also available that can send cell phone or email notifications.
