ABSTRACT:
An actuating mechanism for a plunger-type switch having alternative open and closed conditions and having a plunger movable between an extended position and a retracted position whereby said switch condition is changed by the movement of said plunger comprises a flat spring, having a first spring end, a second spring end and a middle portion, and a housing having an upper surface wherein the plunger-type switch and spring are positioned within the housing such that the first spring end is positioned in closely spaced relation to the plunger in the extended position and the middle portion of the spring bows above the housing upper surface such that application of a force to the middle portion of the spring and directed towards the housing upper surface compresses the spring advancing the spring first end toward the switch a distance sufficient to move the plunger to the retracted position and upon removal of the force the first spring end advances away from the switch a distance sufficient to allow the plunger to move to the extended position.
