The Murphy 0-160 PSI Surface Mount Pressure Swichgage 120 VAC with Latching Control Relay OPLBP-A-160 is a combination pressure indicating gage with adjustable low and high limit switch. This limit switch can be wired directly to electric pilot circuits to operate alarms, shutdown or start/stop of engines and electric motors. The OPLBP-A-160 features a 4-1/2 in. (114 mm) dial for easy viewing. Adjustable limit switch is accessible from the front of the gage and the contacts have a self-cleaning motion to enhance electrical continuity.

The OPLBP is a specialized version of the OPL series designed for start-stop operation of engines and electric motors. The pilot-duty limit switches are connected to an internal latching control relay for ON/OFF automation.
