ABSTRACT:
An improved safety interlock is provided for operating a control switch which enables operator activation of a drive motor of a food processor. The safety interlock comprises an axially movable interlock rod for operating the control switch upon movement of the rod in a first direction. A coil spring is provided for resiliently forcing the interlock rod in the direction opposite to the first direction such that the control switch is normally unoperated. A generally U-shaped channel member receives the interlock rod and coil spring to properly align the interlock rod with the control switch. The channel member is removably connected to the food processor such that the channel member, interlock rod and coil spring can be removed for cleaning or replacement. The U-shaped channel member includes flanges outwardly extending from its open side which are received into first and second tracks on the food processor. Locking tabs at one end of the tracks are frictionally engaged by a notched extension on the channel member to secure the channel member to the food processor. Offset fingers extend beyond one or both surfaces of the flanges to stabilize the flanges within the tracks, yet permit movement and a rocking action within the tracks to facilitate assembly and removal of the channel member from the food processor.
