The 01755 is a standard pressure switch from Gems Sensors. It is designed for industrial and commercial applications, such as low pressure pumps, ejectors, fuel tanks, pumps and valves, and other systems with reduced start/stop pressures. This switch features a solid state design with a built in pressure port, making it very reliable and adjustable. This unit is constructed out of polyphenylene sulfide, a durable plastic that resists abrasion and chemical damage. Additionally, the set pressures are clearly visible, and the protection rating of the switch is IP65.
