Abstract
A control mechanism operable for selectively moving an on-off switch into on and off positions includes an on-off switch having opposed, first and second ends simultaneously movable in opposite directions, an actuator disposed adjacent the on-off switch selectively movable for engaging the first end of the on-off switch and urging it in a first direction to an on position accompanied by movement of the second end of the on-off switch in the opposite direction, and a biasing device disposed adjacent the on-off switch and externally thereof for engaging the second end of the on-off switch and normally maintaining it in the off position. The biasing device yieldably resists movement of the actuator when it engages the first end of the on-off switch and moves it in the first direction toward the on position.
