PRESSURE SWITCH

This switch (A) is used to start or stop the air compressor. Moving the
switch to the ON position will provide automatic power to the
pressure switch which will allow the motor to start when the air tank
pressure is below the factory set cut-in pressure. When in the ON
(AUTO) position, the pressure switch stops the compressor from
charging air when the air tank pressure reaches the factory set cut-
out pressure limit. For ease of starting, this
switch also has a pressure release valve
located on the side of the switch designed to
automatically release compressed air from the
air compressor pump head and its discharge
line when the air compressor reaches the cut-
out pressure limit or is shut off. Moving the
switch to the OFF position will open the
pressure switch contacts and stop the air
compressor.
