737NG Overhead Switch Types? - Need to clarify What Toggle goes Where?

[Michelair]

I was hoping that a fellow member could clarify these 2 questions for me. Oh I am building a Overhead for 737NG


I have several 737-800 Overhead panel diagrams and the toggle switch types are not the same so I am a little confused.

Which overhead switches on the overhead of a 737NG are MON-OFF-MON toggle Switches?

Which overhead switches on the overhead of a 737NG are ON-OFF-ON toggle Switches?

Any and all help is needed.

Thanks again.

Where can I buy these switches you have listed especially the engine start ignition switch which is off-on-mom and landing lights which seem to be off-on-on. Also the starter selector switch which is on left-on both-on right.

After you're clear what kind of switches there are, do a search on ebay or visit your local electronics store, they are all normal everyday switches that can be bought anywhere.
