These float switches are simple and reliable making them perfect for use in salt water environments to activate your boats bilge pump.
Turn your existing bilge pump into a automatic pump which turns itself on and off automatically as the water level in your boats bilge area raises and lowers.
Simple to install, the float triggers a micro switch which opens and closes the circuit. These switches are rated for up to 20 amps current draw in 12V systems making them compatible with most small or large bilge pumps. These switches are also suitable for use in 24V systems with current draws up to 10A.
These switches are designed to turn on when the water level reaches 50mm. As the pump draws the level down, the switch will turn the pump off when the level lowers to ~19mm depth.
Suitable for use in small to large boats, yachts, kayaks, canoes, barges and ships. Popular for vessels left tied to moorings unattended.
