If you haven't sorted it I've found a second hand one of these but it has already been dismantled, probably for repair, and roughly at that.
If you remove the two small countersunk screws, you can lift the switch out, complete with it's die cast alloy mounting plate. The switch is rivetted to this plate but the rivets are part of and consequently of the same die cast alloy as the mounting plate. You can't really remove these rivets without almost destroying them but if you do remove the switch from the plate, it should be easy enough to drill them out without the switch in the way and refit the switch using some tiny countersunk screws and nuts. The black material that the switch is made of is very brittle and someone has repaired this switch and then glued it back together but it should be possible with some patience to get the switch body off without any damage. The switch is actually working though and is available if you need it or even just for the contacts that are in it. You can remove and use your own switch body without damage if you're careful.
I also said that they are fitted with an M.E.S bulb but I was wrong, they are fitted with an M.B.C ( Miniature Bayonet Cap) bulb of about 5 watts but with the small glass 12v or 24v.
