The tumbler switch shown on eBay is heavy. Before installing my miniature printed circuit switch I used to use pliers and physically reverse the wiring on my pickup, another approach that "is not a good idea at all". Anyway, I use a brush to bolster the shell and take care of uneven record surfaces, so excess mass is even less of a problem for me. That's the way I have skinned the cat (not literally!)
