76.PS

A compact and economical pressure switch for extended duty applications. The 76.PS is primarily designed for direct engine mounting, to provide electrical signalling of a low oil pressure fault.

The isolated switch contacts are factory set to close below 15 psi (1 bar), but may be adjusted between 14 and 24 psi (1.0 and 1.6 bar). The polyimide diaphragm is compatible with air, engine oil and other hydrocarbon media. (Contact with waterbased fluids is not recommended.)
