Abstract
A cable operated switching mechanism is provided with a positive locking method that latches a cam structure in place after the cable is pulled by an operator and does not permit the cam structure to return to its normal operating position until manual intervention is used to push a reset plunger. The cable operated switching mechanism provides this positive stop by incorporating a tab on a latching device which is associated with the reset plunger and moves with it when a reset button is pushed by an operator. The tab of the latching device slides along a first surface of the cam structure until the cable is pulled to activate the mechanism. Then, under the influence of a spring, the latching device moves upward to cause the tab to move into a blocking position relative to a second surface of the cam structure. The prevents the cam structure from moving from its actuated position to its normal operating position until a reset button is pushed. This mechanism overcomes a possible problem wherein a loosely assembled cable, with too much slack, could otherwise allow a switch to be activated by the mechanism following deactivation by an operator pulling the cable.
