My friend got one and the switch knob is broken off.  It's a complicated switch, so I don't think I can get a replacement.  It's" Off-On-On"  Isn't that weird and it has two sets of three prongs with all kinds of weird crap wired to them.  I think I'll just try and rig up a switch knob on to it with some drilling and liquid metal.  Any other ideas??
 
Also the light doesn't come on.  Two tiny wires to a little light in a rubber ring.  Any idea what kind of light that is?
 
Thanks,
Terry
