I suspect 4xUM means 4PDT, and SCHALTER-TAST means switch-tactile.

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.

Many thanks anyway.
