| Can a manual switch be wired in parallel with a PIR switch to
| operate a 240v lamp or would this configuration damage/destroy
| the PIR switch?
If the PIR clicks when it triggers, it uses a relay and should be safe to do
Also many outside lamps with inbuilt PIR, which replace an ordinary lamp ie
on the switched live and neutral, no permanent live, have a setting where
flicking the switch in a pattern sets them on to override.
Should be OK for most PIRs, which use a relay as the final switching
element. But they're *not* designed to be overridden in this way, and
you might knacker a cost-reduced PIR switch if you try this. Most PIR
switches have some sort of built-in override anyway - most often a
'flick off, flick on' sequence on the normal switch (wired in series
with the PIR) will put it in 'on till dawn' mode.

 Course, if you're really keen, you can probably find one in Makro
which responds to tapping out the words of the Taiwanese national anthem
in Morse code on the controlling switch at 7wpm or above by playing Jingle
Bells while flashing the controlled light in delicate counterpoint...

That is *exactly* what I'm looking for as a wedding present. URL please.
