Some of us would view that as a benefit/convenience not a problem!
I've not seen a "dimmer-adaptor" like the one shown; I'm intrigued - presumably the bit-with-the-knob is a traditional thyristor-dimmer, wired in series with the live-pins on the 'adaptor' bit?
I remember a similar sort of "regulator" thing - in traditional brown Bakelite - from my youth. It looked like an oversized 13A adapter but only had one socket-outlet, and a knob/dial on the top along with a little window through which a neon-bulb would glow. It was used to regulate the heat to infra-red heater-bulbs in lambing-pens. As the weak lambs got stronger the control would be dialed-back because they no longer needed so much radiant heat to keep them alive. |
In the US, it was a novelty to make table lamps to have a "touch" type dimmer, where all you had to do was touch the metal work on the lamp to select three light levels and off or on. Of course, our lamps are not earthed, because at our lower mains voltage. I actually repaired the dimmer module in a few. Generally it was a shorted triac, that failed because of a short circuit lamp.
I bought a lamp module from a charity shop, that was similar to the one shown. It worked just by plugging a lamp in that had a metal base. It works the same as one that has a dimmer module built in.
Dave, as usual, always collecting.
