Description
PSM-630, a mechanical pressure switch with three pole electrical switching system. It comes with single phase option as well. The switching position of contact depends upon the pressure and diff erential setting done before operation.
The pressure switch is fi tted with a manual on/off knob that will turn off the connected system independent of inlet pressure. Pressure switch with relief valve is used in air compressor, so that pressure can be released from the compressor piston before it starts again. It is suitable for automatic start and stop of the air compressor and water booster pumps.
