WTB: Six position band switch for Heathkit IG-102 RF signal generator...

[M100C]

All,
I'm looking for a six-position band selector switch for my IG-102. If
you've got a junker with a good switch, or know where I can find one,
please email me directly.

Thank you,
M100C

I have a large selection of rotary switches, quite a few with 6 positions.
How many poles do you need? Does this switch have 2 sets of 6 positions on
each wafer? If so, how many wafters does it have? What does the old switch
measure between the bolts that hold the assembly together?

All,
The switch has two wafers (decks A and B in diagram below), six
positions and rotates 180 degrees. The Heathkit part number is
63-212. The diagram gives significant detail as to the functioning of
the switch:

That AR section is a killer, I don't have a wafer with the open circuit
seeking section. But it appears from the schematic that that section is not
used. Is this correct? Are you M1OOC or M100C?

You need to look again. That wafer A, rear section is used to short
out the coils for the bands that are not in use. It is a very special
switch, and the basic design was used in multiple brands of low end
signal generators.

The same type of "open circuit seeking" switch was also used as an input
selector in Hi-Fi preamps and amplifiers.

Well, the OCS switch was used in a lot of places. Every Ledex switch ever
made had one in it to stop the rotation when the selected position was
satisfied.

The schematic I find, is very difficult to read, but importing it into
Photoshop where I can blow it up, I see now that the wafer pins are numbered
to tie to the front section. Sorry M0, I can't help you.

I'd bet most of the Heathkit shop generators used similar switches. I take
it
you can't repair that one? I'd suggest joining the Heathkit group on Yahoo!
It is a very large and very active group.

Try this guy:

He's bought the rights to the legacy Heath literature and has
a ton of spare parts from the company. If he doesn't have it,
I'd expect you'll find a parts unit over at the Yahoo! group.
