OK - Didn't get any quick responses, so I decided to dig into the switch assembly and see for myself. Sure enough, the electrical part of the switch comes off the assembly relatively easily (two allen set-screws) and then the plastic covers can be removed after filing the heads off two rivets. Inside I found a series of electric contacts which are operated by the key via a cam mechanism. Cleaning up the contacts with a jewler's file and some sandpaper seems to have fixed the problem. For how long is to be seen. Saved the cost of the switch for now. In case anyone is taking notes, I drilled through the center of the two rivets and put in some small sheetmetal screws to hold the plastic switch covers together on reassembly.
