Oil Pressure Switch

n38139

Well Known Member
I am looking for an "oil pressure" switch for another project I am working on.

I get the question: Do you want "normally open" or "normally closed"?

I want to put a light on an engine that will come "on" with low oil pressure and be "off" with normal pressure. Anybody have any ideas?
 
You want normally closed. With the application of oil pressure the switch opens, breaks the circuit, and the warning light goes off.
 
The "aviation" versions might be just fine, but there are a million versions of this switch from industrial and automotive suppliers.
