From an office closure some years back, I inherited a very decent extension cable with some kind of filter built in, which resides on the corner of my workbench, and into which are plugged the power supply for the layout, a couple of desk lamps, and the 4-way into which the soldering iron or other power tools get plugged.
It has a solid clunky on-off switch, which is used to isolate everything when I’m not playing.
And MrsD has been briefed to use said switch, and never to turn the lights out if I have forgotten to, as that might just leave something undesirably hot, on...
