A motor assembly is provided for a blind tube mounting the tube having one open end with a tapered inner surface and an opening through the tube downstream of the end and facing the surface. A switch wiper is movably mounted in the opening. The tube may be the handle of a movable tool such as a toothbrush or vegetable peeler or the like. For driving the tool there is provided a sized motor mount that includes a second tubular member with an outer tapered surface for telescopic mating with the tapered inner surface of the tube, the second member having an end vertical wall with a smaller sized motor secured to and cantilevered from the wall and extending into the tube. The second tubular member is an insulating plastic for an electrical barrier between the switch terminals and the motor. There is provided positioning and locating stop means between the second member and the outer tube and outwardly biased terminals on the second member are bridged by the switch wiper, the overall arrangement providing a combination whereby the motor assembly is slid into the blind tube for sealed engagement therewith in a concentric mount with both axial and radial alignment of the switch.
