Float Switch

Float switches detect liquid level mechanically, riding on the surface in a tank, pit or drain pan and switching a pump or alarm the moment the level crosses a set point. Sump and tank jobs hang one when a pump has to start and stop on level without a controller, when a stuck float has let a pit overflow, or when a new tank needs a high-level alarm wired independently of its control system.

 

As an authorized electrical distributor for multiple manufacturers, we stock float switches from Telemecanique and more across competing lines, in a range of connection sizes and cable lengths, so you can match the thread and depth the tank takes, compare switching inputs and ratings across brands, and pick a float rated for the liquid it will sit in.
