Water level switch, is a use of the diaphragm to sense changes in air pressure, so as to promote the switch switch components, it is designed to pressure range of 10mm water column to 500mm water column. Water level switch using water pressure linkage air pressure of the original so as to realize the detection of low water pressure, he designed to pressure precision (up to ± 3mm water column), can be with high current 10A, long service life, affordable and so on.

He is widely used in drum washing machines, dishwashers, bottle washers and other machines that use a fixed amount of water in the amount of precise control of water flow, other medical equipment, drinking fountains and electric water heaters can be used.
