Automatic Switch DC Pump Automatic Switch Bilge Pump Automatic Control Switch

A float switch is a device that uses the principles of gravity and buoyancy to turn a path on or off, thereby turning a circuit or waterway on and off. Float switch that automatically controls the start and stop of submersible pumps The utility model is for a floating switch which can mainly set the upper and lower limits of liquid level and automatically control the start and stop of a submersible pump, including a floating shell and a tethered cable. The circuit in the shell uses a magnetic ring to slide on the reed switch with the rise and fall of the floating shell, so that a bidirectional thyristor is turned on or off, so as to turn the DC power on and off supplied by a rectifier circuit to a relay, in order to reach the relay. The purpose of the contact is to turn on and off the power supply to the pump. The floating switch has a simple and compact structure, is easy to install and operate, can avoid unnecessary energy consumption of the pump, extend the economic life of the
