Is it the red rocker switch or the newer metal toggle switch?
I assume since you say Brewtus it is the red rocker switch.
I would suggest trying Dick Smith in Wangaratta for a replacement and just doing it yourself (or get a sparky to do it if you are not confident). Ive seen several types of the rocker switch that are a proper fit in a local DSE here. In both red and green.
My switch perished on the Expobar some time ago and I found a replacement switch at a Hi-Fi supply store. I just took the old one out (what was left) and took it with me looking. I also took pictures of the orientation and connections before I took it out of the machine.
Theyre about $5 from memory.
Hope that helps.
