I think we need to have a web museum for all the funky electrical fixtures
that have been developed and sold over the last century or so. My own house
could fill volumes with its collection of back stab style outlets, switches,
and fixtures. The last one that I removed, a back stab single pole light
switch needed to be completely disassembled before the wires could be
removed and the act of disassembling it would render it broken - better hope
you get the first install right because you'll need to buy a second one
otherwise. Dissasembly was done with a pair of needlenose pliers - no
screwdriver required.
