Chicago Safety Products RHLGP Pressure Switch

The Chicago Safety Products RHLGP Pressure Switch is a pressure-activated electrical switch that monitors system pressure and changes its contacts to signal or control downstream equipment. It is rated for 125–250 VAC operation, making it suitable for a range of low- to mid-voltage control circuits where a mechanical switching device is preferred over solid-state sensing. The RHLGP model translates pressure readings into a simple on/off action, enabling automatic control of devices such as pumps and compressors or serving as a safety interlock in automated systems. In typical applications, the switch responds to pressure changes by closing or opening its circuit to start or stop equipment, providing a robust, mechanical interface between a pressure source and control circuitry in pneumatic or hydraulic setups. The design emphasizes reliable, real-time switching in industrial environments where straightforward wiring and dependable mechanical operation are important.
