They're in the Trio-mate series from Tyco Electronics. The part numbers are:

5-pin 5-520314-5 or 5-487508-4
7-pin 5-520314-7 or 5-520353-7
10-pin 6-520314-0 or 6-176982-0

I don't know who's got them in stock, though. In a pinch, if you can find
larger ones, you can cut off the extra pins, and visually align the tails
when you plug them in.

The only other thing I can imagine it being is Z6, the 74LS164 shift
register that drives it. Digikey's got 'em.

The only thing I've seen go wrong with sliders is if something falls on them
and bends the stamped metal frame to the point where the slider element
becomes loose and no longer makes reliable contact. Does it feel like the
handle is more wobbly than the others? It might be possible to remove the
slider carefully, pinch the metal tabs that hold the thing together, and get
it to work again.
