Sounds like the Drake remote switch.
Not sure of the model number/designation nor where you could find a
manual, but Drake made a few of those before they went belly-up.
One of the things I picked up at a recent hamfest is the remote head
> for a rotary antenna switch. The switch is nearly 6" square, although
> one side is only 4". It has 6 SO-239 connectors and a terminal strip
> with 8 terminals.
> Opening it up, it has a conventional ceramic wafer switch switching
> the SO-239s, an additional phenolic wafer that attaches back to the
> terminal strip. The rotary switch is driven by what looks like a
> phonograph or clock motor through a geared reduction.
> I'm guessing this unit takes 25-30 vac to run the motor, which then
> stops when the correct detent is chosen. As I don't have the control
> head, I'd appreciate any information on this type of switch. I figure
> I can build a control box pretty easily with the right info.
