Diaphragm Type Pressure Switch

Diaphragm Type Pressure Switch

Diaphragm type pressure switch is a switch which is controled by pressure, it is commonly used in automatic control system . When the pressure value reaches the set point, it will automatically open or close. Pressure switch will restore the original status when the pressure value is lower than the set point.

Feature of Diaphragm type pressure switch:

Diaphragm type pressure switch is Suitable for all kinds of industrial sites, can replace the foreign similar products
