Whale Electric field sensor switch

Totally sealed, with no moving parts, the Whale Field Sensor Automatic Pump Float Switch has a nylon body and will not corrode and is not affected by oil or foreign debris or obstructions.

Suitable for both 12 V and 24 V systems for pumps up to 20 amp rating.

Ideal for bilge pumps, shower pumps and other grey water pumps where reliability is essential.

The switch activates when the water level reaches 51 mm (2″) and deactivates when the water level drops below 13 mm (1/2″) therefore avoiding pump cycling.
