Oil Pressure Switch for Air Compressors and small engines

Description

NOS oil switches used for safety to alert low oil pressure in most pressure lubricated air compressors operating in the 20 to 100 PSI range. These pressure switches are designed to be N.O. at low pressure and will close when pressure reaches their set point of either 15 PSI or 20 PSI. Switch can operate with a proof pressure of 120 PSI. We used these style pressure switches on many different air compressor brands like
Ingersoll
-Rand, Worthington and Davey air compressors that had pressurized oil lubrication.
Switch will close contacts at rising pressure, and will break open the contacts, when falling below the set values. These switches are marked and preset at 15 and 20 PSI, Please choose the
preferred
one above.
Electrical ratings are 12 to 120 Volts, either AC or DC. Terminals are insulated from outer case.
Pressure connection is 1/8" male NPT threads.
