Grrr!

  Tjaart van der Walt and G.Daniel Invent Design wrote referring to a
"cooling" effect of the switch on the live pole.  That's *not* what I
said!

  I suggested that the connection to the switch, being a *smaller* piece
of metal, *not* connected to the incoming cables from the wall, and the
possibility of poor contact in the switch mechanism being an additional
source of heat, means that this (live) contact is *poorly* heat-sunk and
therefore runs *hotter*; not surprisingly; overheating.

  Is that clear?
