Single &Three Phase Pressure Switch is designed for automatic control of pressures in air compressors and pressurized water plants. The Pressure Switch breaks the circuit on increase in the pressure to the set value and re-makes the circuit when pressure fails below to the set value. The Pressure Switch comes in two models such as single and three phase applications. Single &Three Phase Pressure Switch is made of quality grade raw material which ensures optimum durability along with long lasting trouble free service.
