All protective earth wires are permanently bonded together. There
will be seperate earth bonding points so as to enable solid core
connection from the supply and flexible wire connection to the tank.
The permanent conducter between the two earth bonding terminals is not
always completely visible (or at least not obviously).



So there IS a connection from one earth terminal to the other (although not
visible), yes? I should have tested that with my ohm meter, but I was
assuming that the two terminals must surely be connected... and now I am no
longer at the premises.

They will be joined. But as you say, if ever in doubt, a quick
resistance check will tell you what you need to know.

The switch itself is a strange one. It has three red LEDs which shine
through the white plastic switch fascia! (relying on the tranluciency of
the plastic to be visible) - Made by Legrande... Discontinued model!. I
hope that doesn;t mean it was a bad design in some way. Otherwise, I'm
surprised they discontinued it, because aesthetically, I think it's nicer-
than the type with a small red plastic window with a neon bulb behind.

Thanks to all for the clarifications.
