9003 Auto Float Switch. This Float switch features an Electrical Field Sensor, which will automatically sense water levels, and act immediately to turn on your Bilge Pump when the water level reaches 51mm, and will turn off at 13mm, a feature offering the boat owner peace of mind and security. The 9003 Float switch runs off 12/24 VDC and is suitable for up to 20 Amps, easilly withstanding high temperatures during operation. The Float Switch is compatable with our range of Whale Bilge Pumps and other accessories.
This Whale bilge water sensor can be easily mounted on the base or on its side to suit your requirements. It also has two colour coded wires for simple installation, and also features two testing points to ensure it is working correctly.
