ID this switch for a Mutron AutoWah w/photo

[PRNDL]

I need help finding a replacement switch for a Mutron Auto Wah mode selector.
It's a ceramic 1P3T rotary switch with four posts on one edge and three on the other.
I've attached three photos (the shaft is broken off).
There are numbers stamped on it: 5708-001 137 7917

I'd like to know where to get a replacement.

Thanks!!

(the shaft is broken off).

The only way to find an exact replacement will probably be another dead unit.

There was a company doing repros of these, but I'd doubt that they used the original switch in their design. But, I guess you could try and contact them if they are still around.

What I've done in the past with problems like this one is to re-use the switch wafer and install it on a different shaft assembly. From what I remember, there are only a few different standard rotational degree standards, so finding another switch that had click stops in the right spots wasn't too hard. Then you just need to modify the rotation stop blocks to limit the number of positions.

Maybe give Haz Labs a call

although the new one (Mutron +) has a four pole switch on the old schematic
its a single pole 3 position changeover switch marked " Mode Switch 0502 "

Have you looked through a large catalog like Allied? They should have rotary switches, and probably pc mount ones, but even if the wafer has solder lugs, you could add on little solid wire stubs from each and solder them to the board. The switch would ultimately be supported by the nut on the bushing, not the wires.

That is a 30 year old CTS product.

I don't think the "reissue" has much in common with the original. I have heard that they are digital based, but I haven't been inside one to confirm.

Expanding on what Enzo already pointed out, it sure looks a lot like the one pictured here:

The PDF download outlines the part options.

It also looks like they come in a wide variety of shaft styles, number of positions, PC or wire mount, etc. Which also probably means they cater mostly to OEM's in large quantities. If the measurements are correct and you can figure out the correct part number (and you have a good line of BS about being a manufacturer ) you might be able to order some "engineering samples" direct from CTS.

If you Google Mutron, you'll find a site run by Mike Beigel, the original designer of the Mutron line of FX. Maybe try to contact him for suggestions. For all we know, he might have a drawer full of them!
