The Attwood Automatic Float Switch lets you create the perfect control system for bilge pump. The switch helps convert manual operation of a 12 amp/6amp pump to automatic operation. It triggers pump operation when the water level is 2" high, and when the bilge is empty, the pump is automatically shut down.

Featuring a compact low-profile design, this float switch easily installs on any horizontal or up to 24⁰ angled surface. The entire switch system is completely sealed to resist moisture and avoid electric shock. This switch contains no mercury, which makes it an earth-friendly product.

  • Triggers pump at 2" water level
  • Sealed switch mechanism
  • Perfect for pumps that draw 12 amps, 6 amps and less
