I think you will find that the "transformer" is actually the ballast
for the "circline" fluorescent tube. The button that controls this
part of the fixture may serve two functions - a. it controls on/off of
power to the ballast, or this could be a function of the button for
the incandescent bulb. b. it serves as a momentary contact to energize
the heater elements which create the mercury vapor conductive path in
the fluorescent tube.

Hmm, sure looks like a standard transformer! Made by Precision
Transformer. As for switches, one clicks on and stays on until turned
off by the center button. The other is momentary contact. Both bulbs can
be on at the same time, center button will turn both off.

Just bought the LED conversion, $36. Just have to head to Jaycar to buy
some suitable switches.
