Default Lamp Dimmer

Thanks to all who helped me on this project. The lamp is now back in
service. The dimmer works perfectly. I wasn't able to fix the switch
because I couldn't figure out how to replace the spring contact that
came out when I opened the bottom of the potentiometer case, so I
jumpered accross the contacts and plugged the line cord into a
switched power strip.

When I turn the dimmer to the off position (max resistance), the bulb
turns off completely. Does the lamp still use power in this position?


yes, and quite a bit too. Dimmers are often described as devices for
turning down the efficiency of light bulbs. No light output comes from
somewhere roughly in the region of 50% power consumption.


If it's not too much trouble, I'd like to fix this "right". Is there
any reasonable chance that I could find a 300K ohm pot with integrated
switch that would fit directly onto the circuit board?


yes certainly. 300k is an unusual value though, are you sure thats
right?

If not, where
is a good place to buy a 100W 120V dimmer module?
