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.

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.

Not that uncommon. Mains switches may just have brass contacts which
corrode. The relatively high current with mains tends to keep them clean
(the spark as they operate)

Signal switches usually have plated contacts to prevent corrosion.
