Certainly no fish oil in that lot. It is almost entirely petroleum based.

Jamie has been told he is wrong about WD-40 several times, bt he
continues to post his crap. He ignores the MSDS data every time it's
presented as evidence. He claims to be an electrical engineer, yet
makes the most basic mistakes all the time.

Maybe just a little WD40 down the shaft will do the trick - not a
whole flood of it mind you.

Don't want that precious console to wind up looking like Venice.....

WD-40 (fish oil as main ingredient or used to be) dries out.

Spraying the contacts for suspected electrical issues, only
temporarily fixes, and normally makes it worse afterwards.

Which is why I won't be doing that.

** Wot an imbecile.

Indeed.

Instead I have contacted the sales director of Shuttlesound to find out why his
company does not keep adequate spares stock and contacted Bosch/Telex directly
to try and identify the switch.

Incidentally, despite the wording on the back, it was NOT designed in the UK at
all, but entirely by Dynacord. Probably explains the diabolical inter-channel
crosstalk.

Have a look at the below link. From what I gather, the actual brand is
"Schalter", which is owned by Assmann. "Tast" is German for "test", which I
suppose is actually a colloquial expression of a function, I don't know
what.

Page down. Besides the DIP switches, there is a type called a "taster."

All this talk about Assmanns, DIPs and tasters is getting me excited!

After a few carefully considered phone calls and emails, not least to the
manufacturer and the sales director of the agent, the switch has
mysteriously appeared 'in stock' !

The spares guy made out he'd been ordering some in all along which is funny
since he didn't mention that on Friday !

Nearly forgot !

Thanks everyone for all the positive input.

I'm repairing a Midas Venice mixing console. Try and avoid doing so.
It's a nightmare

Despite the agent's tech insisting that the 'solo' switches are 'self
cleaning', no amount of exercising them will prevent 2 of them behaving
intermittently.

They are pcb vertical mount types, i.e. the control surface is a series
of large flat double sided boards. From appearance I guessed the
switches to be ALPS but the German parts list gives the following
reference as best as I can decode it.

SCHALTER-TAST 4XUM 1 switch 4pdt

It's a latching type btw.

Any help sourcing same would be appreciated. I only need 2 but knowing
this beast one or two more might pack up !

The Ampex ATR700 decks use a switch that might be the same beast. It is a
PCB that slides into the pushbutton. I've seen spares for sale on the net
for that switch. You might want to search for ampex parts. AMpex mailing
list or something like that.

Thanks but that doesn't sound like it. I'm fairly confident it's an ALPS (or
similar) part.
