Oil Pressure (Idiot Light) Switch for Atlas

Anybody have a Part No. or recommendation for an oil pressure switch to fit an Atlas? I want something to replace the plug under the pressure relief valve in the timing cover.

Sorry but I think most motorcycle manufactures stopped fitting an oil pressure gauge in the (I think ) late 1940s, or was it 50s.
I have heard/read of someone on a Triumph twin have to make an adapter to fit one.

Don't the (later) unit Triumph engines have an oil pressure gauge sticking out forward low on the rhs side of them ?

Seem to recall the thread is something odd, so you'd need an adapter.
You also need to know what pressure they are set for - 7 psi ??
Or they will false trigger all the time.

It may also be like a Guzzi, where the dealer commented that if the oil light comes on, its too late...
Which means Guzzi also have a pressure sensor - probably also with odd threads.
