Stainless Steel Double Ball Float Switch, Liquid Float Switches, Water Level Controller Sensor Switch for Tank Pool (100mm)

The float switch cannot directly control solenoid valves or high-power relays, AC contactors, etc. A small relay (like HH54P) is needed for the transition.

The double float switch can be used to control the liquid level of a water tank, pool, sink, fish tank, etc. (drain or water), or to create an upper and lower alarm switch for the liquid level.

The contacts inside are made of a reed switch with very high sensitivity.

The stroke of the two floats in the double float switch is 10 mm. If the control range is large, two float switches can be used, allowing for a greater stroke and preventing frequent pump starts.

The normal water inlet process is activated by the lower float, and the upper float stops it. Draining is activated by the upper float, and the lower float stops it.
