Pressure Switch

Indfos Industries offers Pressure Switch, PS/PSU Series. This is a triple pole device, now introduced with more elegant housing, modified design and with a user-friendly manual over-riding switch. These switches cut off a 3-phase power supply when the pressure rises to a preset value and cuts in the power supply when the pressure falls to another predetermined value. Both cut off and cut in pressures are independently adjustable. Type PSU is additionally provided with a relief valve, which ensures load free starting of the compressor. Type PS/PSU pressure switches can be readily used by manufacturers of small air compressors and domestic water pressurisation systems, etc.
