  • Patent number: 5107720
    Abstract: An actuator for operating a remotely positioned, for example, spring-biased latch mechanism, or mechanical actuator, by a sheathed control cable. The actuating mechanism includes a plastic housing having a pivotally mounted, hand-operated member provided with two spaced zones for receiving at least one end of a flexible control cable. The housing is also provided with a pair of elements which secure the control cable sheath adjacent each of the pair of spaced zones for receiving one end of a flexible control cable. The two positions, or spaced zones, for receiving the flexible control cable are spaced at different distances from a pivot pin for the lever actuator.
