ABSTRACT:
An actuator assembly for a small, versatile electrical switch of the type which includes a thimble telescoped over and axially slidable on a guide stud disposed between spaced conductor ends which are engaged by flanges of the thimble in a retracted position. The switch also includes a floating sleeve having radial latch dogs which are rotated during engagement with circumferentially spaced holding ribs in a surrounding housing to establish projected and retracted positions for the thimble. The actuator mechanism includes a strand of monofilament material extending through aligned apertures formed axially through the switch with a tie knot in an end of the strand adjacent an outer surface of a plunger acting to depress the thimble to engage or disengage an electrical connection within the switch in response to an operator pulling on a free end of the strand actuator.
