Don't let the prices shown shock you. Like I said, I went to a local electric supply shop, described what I was trying to accomplish, and he walked me to the back supply room with the boxes of inventory, reached in and said "like this". And it was exactly what I wanted.
Thanks for the info - I guess the trick is to use "vandal proof" to search...
I'll replace my ugly AC spruce one now -
...and I'll check our local electrical outlet.
I presume that quite a long physical movement of the button is required to actuate the switch, Apem did not seem to give a spec.
