Murphy High - Low Switch (Choose Your PSI) All versions feature a 4-1/2 in. (114 mm) dial for easy viewing. Adjustable limit switches are accessible from front of the swichgage instrument. Limit contacts have self-cleaning motion to enhance electrical continuity. The OPL-series pressure swichgage instruments are combination pressure indicating gauges with adjustable low and high limit switches. Limit switches can be wired directly to electric pilot circuits to operate alarms, shutdown or start/stop of engines and electric motors. The OPLC is a surface mount, indicating, pressure gauge and switch. Adjustable high and low limit, ungrounded contacts are used to operate alarm, shutdown or start-stop circuits. Pointer closure against either of the adjustable contacts completes the pilot-duty circuit. Pulsation Dampeners are recommended to be used in line with these gauges to ensure gauge longevity.

TATTLETALE® annunciators and Magnetic Switches are the nerve centers that translate SWICHGAGE® contact operations into decisions and operate the alarm or shutdown device. They are the electrical load carrying devices for the alarm or shutdown device. TATTLETALE® annunciators indicate which monitored function failed leading to the alarm or shutdown whereas magnetic switches do not. Magnetic switches operate basically as a latching relay. *Multi-voltage AC or DC systems. Coil Resistances (OHMS): 822PH - 30
