22cm Dual Ball Water Level Sensor Vertical Liquid Float Switch Fish Tank Pool Rivet Nuts Used widely on the admittingA float switch is a device used to sense the level of liquid within a tank. The switch may actuate a pump, an indicator, an alarm, or other device. It can be easily converted from normally open to normally close by invertin the float.
