Ah yes. One thing I never did understand was that the one common fault
on torches was poor contacts in switches or between battery and the
rest of the circuit. You would have thought that would have been
solvable.

It is. But may cost. Like decent gold etc plating. Not only do you need to
prevent the contacts corroding, but you also need any plating to be
thick/strong enough to last well too.

Maybe in the case of my switch then what I shouldhave done is to take it
out and use it on mains for a few days. Not practical. Brian

Why not just use the correct type of switch? Rotary or sliding contacts
tend to work best for signal levels.

Got a switch story from my old car. The window switches control relays.
The exact same Lucas switch is used on other makes with no relays. On
mine, the switches need regular cleaning. In the high power use, not.
