Abstract of the Disclosure A tandem electrical control comprises a plurality of variable resistance sections. Each resistance section comprises a resistance element and a collector member that are carried by a base, and a contactor member that is carried by a driver, the contactor member is rotatably supported within the respective housing and wipingly engages the respective resistance element and collector member. A tubular shaft controls the forward resistance section and is rotatably supported within a bore of a mounting bushing. A inner shaft controls the rearward variable resistance section and a switch and is rotatably supported within the tubular shaft. The bore of the mounting bushing, the outside diameter of abutting engagement with the proximate one of the shoulders for preventing impact damage to the resistance assemblies from external forces axially applied to the shafts. One of the collector members is provided with at least one radially elongated depression and a contacting protrusion is disposed on the corresponding contactor member so that when the contactor protrusion engages the collector depression a tactile sensation is transmitted to the corresponding shaft.
