PRESSURE SWITCHES
Pressure switches are used as excess-pressure and under-pressure differential monitoring devices for natural gas, liquified gas and air in gas supplying and ventilation systems.
Pressure switches monitor extremely slight pressure differences and provide for electrical disconnection of a system when the set value is reached.
