Out of interest, is there a thin spray lube that's OK for switches,

PTFE dry-film lubricating spray.

Contains tiny balls of PTFE (Teflon) suspended in volatile solvents.
The solvents evaporate leaving the PTFE as a dry-film lubricant.

Apart from generally being bad, WD40 has a tendency to get onto the
key and then stain your hands/clothes, so it's a bad idea for this reason
alone.

Then why do Yale reccommend WD40 in black & white? Arrrrghh!
