The liquid level switch is also called the water level switch.

Liquid level switch
       The liquid level switch, also called the water level switch, the liquid level sensor, as the name suggests, is the switch used to control the liquid level. Formally divided into contact and non-contact.
       Commonly used non-contact switches have capacitive liquid level switches, and contact float type liquid level switches are widely used*. Electrode type liquid level switch, electronic liquid level switch, and capacitive liquid level switch can also be realized by contact method.
Common principle of liquid level switch
       Washing machines are white goods that are widely used worldwide. In recent years, with the shortage of water resources and the market demand for energy-saving and environmental protection performance of home appliances, especially in Europe and North America, water-saving indicators for home appliances have entered the legislative process, and good water-saving performance has become a new generation. The important technical development trend of intelligent and green washing machines.
The core of the water-saving technology is to control the amount of water in the washing machine drum. It also means that the liquid level is first measured. According to the customer demand survey of several major manufacturers around the world, the requirements for liquid level measurement.
