I don't think you are odd, most people in fact like it like that.

This is 4 position. Not sure the terminals are compatible though.

So took switch out of Case 446. It looks to be the same as what came out of the MF 16. And I would say nether are original. But they work.

Noel.

M is for magneto ignition you need is battery ignition .

I looked that up . it is for magneto ignition .

[propane1]

Yes I know they are magneto ignition switches. But that’s what In the Case 446. And it works.
Somebody figured out this switch would work some how and maybe reworked the connections on to the switch to make it work.

If I could figure out the number of this switch. I’m sure it would work in the MF 16.

I think this applies to your S, A, M, B, G. Just replace A (accessory) with L (lights). Better yet, measure with an ohmmeter and see how you can assign terminals to this diagram.

That’s only a 3 position switch Eugen.

Yes. The switch I took out of the Case 446 this afternoon, is a 4 position one. And it has a M, G, A, B and S terminals. And it works in this tractor. Notice the picture of the dash. 4 key switch positions.
