Oil pressure switch

[happyendings]

My buddy's trawler has two Lehman diesels. On the starboard engine, the oil pressure switch for the alternator field crapped out. He wants to install another one even though his present alternator is a relatively output unit and really doesn't need it. Anyone have a cross reference for a 1/8" NPT two wire oil pressure switch. Any brand will do but would like to be able to go to the auto parts store or some other place local. I did find a Carter 68301 that fills the bill but none of the auto parts stores in town has a cross reference. This switch would fit my Yanmar 3GM's and my Westerbeke 5.0 BCD genset so I have a little extra incentive to find a match.

Closing pressures
PS11 5psi
PS12 10psi
PS3 20psi.

I got them for switching alternators on from Lewis Marine, Fort Lauderdale.
Hard to find elsewhere.
