Spoke too soon! Just got an email from TTi saying that although the switches used in this TS3022S are unobtainable, they have stocks of a slightly different switch which was used in them from 1991-on.

Pretty expensive at £11+ each, but not as expensive as throwing away an otherwise decent power supply. The unit is in good condition so I would rather fit the right switch than bodge something in.

There are three identical switches, one used as mains on / off and the other two for the left DC and right DC output. The one which has failed is the right channel DC on / off switch - given that the replacements are expensive and don't quite look the same, I'll probably move what is currently the mains switch to the right DC channel and fit the new (slightly different) switch as the mains switch.
