I am looking for a not working Braun Multipratic UK40 to buy. I need in particular the rotating power switch, cod.4 292 029, soldered on the the electronic card cod.4292045-5. Because of the spare part are no more available, I am prepared to purchase an old blender. Please, contact me at "ailanders*tiscalinet.it" (NOTE: sobstitute the char * with @)
