Oil pressure switches are an odd shape - and it just so happens that there's a special socket available to install or remove them. Here's our review of the Lisle 13200 Oil Pressure Switch Socket (eBay).
Firstly, there's no chrome here - it's all industrial finish:
The packaging - not that it's really packaging, more the plastic tag attached to the socket - isn't really forthcoming with a lot of information:
The socket fits most 1" and 1 1/16" oil pressure switches - which covers a fair range of vehicles, from some GM models to Hondas and more.
Here's an example of an oil pressure switch - this one in particular is from a Honda CX500 engine:
It's a perfect fit:
There's a warning on the socket not to use it on oil pressure switches while the engine is running...
The socket is 3/8" drive, or alternately you can use a 1 1/8" socket to drive it. The overall height of the socket is 1 7/8".
The socket fits what it's supposed to and isn't terribly expensive, so we can recommend it if you have a matching oil pressure switch that you need to tighten or loosen!
