Hi
I vaguely remember a teardown video from a few years ago, in which I've seen this (maybe as part of a mailbag? not sure)...
Some random piece of lab gear was taken apart, unfortunately I do not recall what it was.
As it is tradition, the actual power switch was near the back of the unit, the power button in the front panel.
Though, there was no bent plastic rod, instead a rather elegant bowden cable.
Does anybody here understand what I am talking about?
