Product Details

A vital tool to start your backup pump/s running if the main water-flow stops for any reason!  Power failure?  On it goes.  Clogged or burned-out main pump?  Backup pump starts!  Great security for your fish!

This good-quality float switch is actually designed to start a DC pump if water level rises.  In aquaponics, we mount it upside down in a header tank (not included), so that, if the water level in the tank falls due to the water flow being stopped, the switch will start a backup pump (not included) to keep water turning over in the fish tank, providing emergency aeration and water cycling.

  • Rule brand Rule-a-matic model 35A
  • Sutiable for 12 V & 24 V DC applications
  • Max. amps at 12 V - 14 A
  • Max. amps at 24 V - 7 A
  • Mercury free
  • Wire length - 700 mm (28")
  • Wire gauge - 1.3 mm2 (AWG 16)

The switch can easily be slipped out of its base for installation or cleaning.

A great switch for automatically starting your backup pump/s in emergency situations.  Get one today to protect your fish!


Perfect for use with the 12 V pumps we carry.

You can also buy this float switch already installed into a small header tank designed especially for it.  How easy is that!
