Rotary potentiometer 1-10 V home electronics. Electronic rotary potentiometer 1-10 V, for switching and controlling electronic ballasts and Tronic transformers with 1-10 V interface, e.g. for fluorescent lamps and low-voltage halogen lamps, with push-button switch, basic brightness adjustable, short-circuit proof and overload proof (fine fuse), with spare fuse, with screw terminals, fuse can be changed without removing the cover. When using low-voltage halogen lamps, we recommend Berker Tronic transformer with 1-10 V interface, for use with covers.
