About Pressure Switches

Compact Pressure Switches
With a round body that’s at least one-third thinner than traditional pressure switches, these fit in tight, cramped spaces. They’re often built into pumps and hydraulic systems with limited space in order to turn equipment on and off, activate automated controls, or signal alarms when they reach a set pressure. These switches are single pole, double throw (SPDT) and can either turn one device from off to on (normally open) or on to off (normally closed). They also meet at least one American, Canadian, or European safety standard.
Switches with an external setpoint adjustment have an external ring, so you can set the pressure quickly by hand. NEMA 4 rated switches stand up to dusty and washdown areas as well as the outdoor elements.
