This thing was a real pain when trying to figure out the connections. The think I can't show are the rods or pin through the body that the leaf springs on the back are pushing against to make the contacts with the switch piece. If it hadn't of been for Keith Townsend sending me the patent drawing for this switch, I would've never figured the bloody thing out.

Anyway, take a look and let me know what you think

The nut for the housing is hex, not square. Also, the screw is special, and has a shoulder just under the head.

Larry, how far does that shoulder go down the screw? Will this do? Or is it longer or shorter?

Is the sheet metal housing the same as the one with only a horn button, or is it unique to the combo-switch?

Nope, it's the same...just got different guts stuffed in it



Larry, I got to thinking about that shoulder and decided if they were going to make the screw unique like that it probably went clear down to just a few threads at the bottom of the screw...or course none of the repop's today have a screw like that, which is why I drew it with the modern screw.

The shoulder goes down about 1/4" from the head. I also failed to mention the entire screw and nut are raven finished.

The nut is quite thin.

Wooo, ok, that's good to know too.

I have seen them with Ford Logo or the BASCO logo, like in Phil's photo. That BASCO logo is still in use today and I believe stands for Briggs and Stratton Co.

I know I've seen the logo's too, but they're on the back of contact plate...if they were anywhere on the front I would've put them in just for the fun of it. :-)

Ok, here's an update.

The photo that Keith posted shows the correct screw and nut, and the shoulder is indeed 1/4". The threads are 8-32 and the screw is raven finished. I just located a NOS one I have. It is the same screw used on the standard horn switch.

Oh, ok I see what you're saying now Larry...
