Thanks all for the answers it makes total sense now.
Im looking at working with a dimmable electronic ballast for my latest
project. The on/off and dimming function is control via a push to make
switch which seems like a simple way to set it up. Unfortunately the
switch needs to be located in a prominent position and it looks
unlikely I can get one to match the required decore and existing
switches (brushed chrome look).
Cheers,
