Product details

Water can accumulate in the bilge from time to time for a variety of reasons, be it rain, a leaking valve or a through hull. In order to be able to pump out this water automatically, float switches are required.

This Attwood float switch can used to switch a bilge pump to fully automatic operation. The switch features a compact, low-profile design and can be mounted horizontally on any surface up to a 24° angle. An integrated switch activates the pump at a water level of 50mm and deactivates it when the water level falls below 10mm.
