A pressure switch is
simply a device that reacts to the changing pressure in a system.
As it reacts to that pressure change in the system the pressure
switch generates or drops an outgoing signal that is used to
initiate another action. In the case of an air compressor, the
"another action" is to turn on or turn off the electric motor.
Because there are so many different types of air compressors,
electrically driven, rotary screw, reciprocating and natural gas, a
dependable air compressor pressure switch is key to the delivered
service. An unloader valve that senses line pressure and
provides a control signal to system valves is a feature to make
sure your air compressor pressure switch is equipped with.
When considering an air
compressor switch look at these different suggestions before
purchasing; operating pressure range, type of fluid: gas or
liquid, sensor mechanism for the pressure switch and the operating
temperature. A disconnect metal lever is also recommended in
manually turning off the compressor. Other features to look
for are a no drift pressure setting, corrosion proof covers and a
