Float Switch - Water Tank Pump Control

WATER TANK FLOAT SWITCH This is a Paddle type float switch with weight and 3m PVC cable long enough to connect to your suitable power source and the pump. The switch is suitable for both high level and low level control according to the wiring connections. It regulates the water level with the pump operations so that once the tank is full, it limits the pump control by switching it off in order to prevent overflow.

Float switch also known as mechanical switch floats vertically on top of a liquid surface. The float switch opens or closes depending on the pre-set trigger and counter weight. It produces an electric current which flows through it to the connected device. The connected device on the other side stops or starts the inflow of the liquid.

Float switches have a major role in managing storage tank systems. Whether the tank holds oil, water or any other substance, float switches can be used to manage the liquid levels, operate equipment and they can play an important role in protecting equipment that may get damaged by improper operation.

A float switch consists of a hollow floating body and an internal switch, also called a sensor. The most common internal switch is a reed switch, so there is also a magnet inside the body. There are other types of internal switches, but the working principle that they open/close due to gravity and water level moving the float switch vertically up or down is the same. Therefore, the mechanical switch creates an open or closed electrical circuit.
