I deleted the original post because of misleading info from my bad memory, sorry. I've been having some trouble from my oil pressure switch, and was looking to replace it soon. I think a suitable replacement can be had at a reasonable cost from an auto parts store. I looked up the updated Honda PN: 37240-P13-013 to see if it was listed for any automobiles and found it was used on a 1982 Honda Accord too. Cross-referencing based on use with this car I found the follow list of suitable replacements:
OEM Honda - 37240-P13-013 (4.0-7.1 psi)
Beck Arnley - 201-1679 (2.0-6.0 psi)
Standard Motor Parts - PS138 (3.0-7.5 psi)
Standard Motor Parts - PS200 (2.0-6.0 psi)
Borg Warner - S4135
NTC - W0133-1641247
FAE - ATM1431005
NAPA (ECHLIN) - OP6075
NAPA (MPE) - OP6075SP
AIRTEX/WELLS - 1S6691 (2.0-6.0 psi)
All of these are listed as male connector, but some use a screw and others use a post. It seems to vary from parts lot to parts lot, even from same manufacturer with same part number. I listed the trigger pressure ranges when I could find them listed. I personally don't think a psi or two variation amounts to anything when dealing with "dummy lights." I strongly recommend using a pressure gauge if you don't have one installed already.
