I was told by mechanic that I need a new power steering pressure switch for my Mitsubishi Galant 2003.
They cannot find it anywhere and I looked and could not find the part.

I noticed some people list the power steering pressure switch together with oil pressure switch like this for example "SWITCH,P/S OIL PRESSURE".

My question is can I use an oil pressure switch which is easily obtained, for the power steering pressure switch?
