1. An improved actuating device having a rotatable member, an actuating member interconnected with said rotatable member for rotation therewith, and drive means for selectively rotating and stopping said rotatable member, said device including a magnetically actuable switch for controlling the actuation and de-actuation of said drive means, said switch being biased toward one of either its open or closed positions, a plunger having a magnet thereon and being movable between a first plunger position in sufficiently close magnetic proximity with said magnetically actuable switch for magnetically actuating said switch to move to the other of its open or closed positions and a second plunger position spaced sufficiently magnetically away from said switch allowing said switch to move to said one of its open or closed positions, said plunger being biased toward said second position, said rotatable member having first and second surfaces thereon engageable with said plunger, said first surface urging said plunger into said first plunger position when said rotatable member is in a predetermined first rotational position, and said second surface allowing said plunger to return to its biased second position when said rotatable member is in a predetermined second rotational position, whereby said drive means is actuated or de-actuated in response to the rotational position of said rotatable member.
