View Full Version : Oil pressure switch tests

I posted a couple of weeks ago in the vendors section about needing a reliable replica oil pressure switch. I purchased 6 new replicas made in India, and tested them and 1 new Standard late switch. Also 3 used early, 1 shovel and 2 evo switches. Tested each several times cold and also at 150 degrees. Most seemed to open and close at a lower psi when heated.

This is great info. Looks like this may drive the prices up on original switches.:)
