ABSTRACT:
A control device for an electrical circuit has switch means adapted for movement between circuit making and breaking positions including means for stiffening the switch means having a force receiving end spaced therefrom. Fulcrum means is disposed for pivoting engagement with the switch means. Means is operable for applying a control force onto the force receiving end of the stiffening means so as to yield the switch means in its circuit making position into pivotal engagement with the fulcrum means and thereafter pivotally move a part of the switch means about the fulcrum means toward the circuit breaking position.
A method of operating a control device is also disclosed.
