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 !

I have a bunch of finds, none of which may be relevant, but I pass them on to you. The most interesting is http://www.henri-electronic.de/start.php?P_989.php, which depicts a bat-handle Schalter 4XUM.
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.

That sounds very likely indeed.
I'd imagined SCHALTER might be the brand but that puts a new light on it. However browsing the ALPS website which I took to be the best bet, I couldn't find any 4 pole switches of that style. Maybe I'll look again.

Nope, none of those. That's when consoles had 'real' switches instead of using consumer parts ! You'll find those on my first home-made desk.

Those are the small low profile tact(ile) switches. This one is much taller.

No luck with that other than blind alleys.
From Franc's comments I'm thinking again it may be more likely to be an ALPS part that I didn't see in the online catalogue. Midas do make a point of using ALPS parts.

Schalter means switch. "Tast" is most probably an abbreviation for "Taster", which is a switch that closes (or opens) the connection only as long as you push it, rather than making the connection until you push it again. What would be the English term for that kind of switch?

Momentary as opposed to latching.
But this is actually a latching switch. Maybe I selected the wrong part number.

** Obviously YOU lack the necessary Midas touch !!!!!
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.....
