Pressure Switch

Salient Features


Exceptionally long life.

Smooth, trouble free operation.

Use of bimetallic contact buttons having a thick layer of silver (Ag Cdo 10%) for longer life of switching cycles.

Bakelite contact block made of superior electrical grade of phenol formaldehyde powder for very good electrical & mechanical properties.

A wide range of differential pressure setting available between starting and stopping pressure.

Glossy, scratch resistant, anti-corrosive colour coating for the outer sheet metal casing for longer life & attractive appearance.

Very rigorous electrical and mechanical tests for every switch in our well equipped factory.

Slick, superior finish.


APPLICATION : Pressures switches, type PR & PRV, are designed for automatically starting & stopping motors of compressors & pressurized water plants.

TYPE PR : Type PRV are triple pole pressures switches without unloading valve.


TYPE PRV : Type PRV are pressure switches provided with an unloader valve which relieves the pressure over the compressor piston when the electric motor stops. Hence, when the compressor restarts, there is no gauge pressure on the compressor piston and as a result the electric motor life & compressor life increase.
MOUNTING ON COMPRESSOR : The pressure switches are designed for fitting to the air receiver by means connection(1/2"BSP).


UNLOADING FUNCTION (TYPE PRV) : Unloading valve(4) be connected to the delivery line between the compressor and the receiver 1/4 in. flare connection provided.


ADJUSTMENT : The stopping pressure is set by turning the regulating nut (1) and the starting pressure, which depends on the differential, by turning the regulating screw(2).
Start the plant. when the stopping pressure required is reached, turn the regulating nut (1) anti - clock wise until the plant stops.
If the plant stops before the pressure required is reached, the nut should be turned clock wise.
Turning the regulating screw (2) anti - clock wise reduces the differential (increases the starting pressure) while turning it clock wise increases the differential pressure.


MEDIUM & TEMPERATURE : They are suitable for Air & Water & can withstand temperature of medium 211 F (100 C.
