A bilge pump switch that utilizes new technology where patented Mirus effect detector cells produce micro-electrical fields that detect disruptions caused by water and fluid. Detector cells are totally sealed and are never in contact with the water and so will not corrode and are not affected by oil or foreign debris.

The float switch automatically activates at a fluid level of 50mm and deactivates at 20mm. In addition, the electronics within the float switch incorporate an 8-second delay to ensure that the water level is true. The two wire device is fully submersible.

Warranty Length:
3 Years.
