Oil pressure switch
Turbo Mini Forums

Got a problem and thought I solved it but clearly it's the switches not up to the job/pressure. The one I got has three connections normally open untill pressure is reached then it's normally closed. I use it for controlling my fuel pump.
Problem I have is that after a few months the switch starts weeping oil. My pressure at out most is 75 psi obviously under load. Do you guys know where I can get one up for the job or am I going to have to go to a single contact switch and rewire into a relay?

Go single contact as per the original part and have your warning light earthing through a relay. thereby when your oil pressure light is on the relay is energised to the open position, when the light is out the relay de-energises and switches the power to feed the pump. This is how I wired my pump in. Obviously you need a relay that can be wired normaly closed or normaly open.

Much the same as the Maestro Turbo's but they also have the knock switch inline with this curcuit.
