1. In an arrangement for shifting an off-on electrical switch, between off and on positions, that is remote from the operator, in which arrangement the switch is mounted in a fixedly mounted switch box and includes a rocker arm for shifting the switch between its said positions, an electrically insulated actuator mechanism for actuation by the operator, which actuator mechanism is located remotely from said box, and drive rod means extending between said box and said actuator mechanism and operatively connected between said switch rocker arm and said mechanism for effecting shifting of said switch between its said positions utilizing said actuator mechanism, the improvement wherein:

  • said actuator mechanism is mounted in an electrically isolated box and includes a rocker arm adapted to be hand operated by the operator.electrical conduiting extending between said boxes,said conduiting having one of its ends connected to said switch box and the other of its ends connected to said isolated box,said conduiting ends being connected to the respective boxes by electrical fitting means each including a tubular body extending into the respective boxes and means for making the respective bodies fast to their respective boxes,said drive rod means comprising;

    a guide tube extending between said boxes and through said conduiting and said bodies of the respective fitting means,each of said fitting means bodies having a compressible bushing press fitted therein into compressed gripping relation with said guide tube,stop means carried by said guide tube for maintaining the respective bushings in said gripping relation with said guide tube,and a drive rod extending through said guide tube and having one of its ends operably connected to said switch rocker arm and the other of its ends operably connected to said actuator mechanism rocker arm,said guide tube and said drive rod being formed from materials of self lubricating characteristics and being resiliently flexible laterally thereof whereby said conduiting may be shaped in diverse configurations between said boxes and said guide tube may be housed within said conduiting in substantial conformity to the configuration of said conduiting longitudinally thereof,said electrical conduiting being free of electrical wiring extending therethrough,said means for maintaining the respective bushings in their said gripping relations with said guide tube comprising clamp devices fixed to said guide tube within the respective boxes and substantially abutting the respective bushings,said bushings being jam fitted in their respective fitting means bodies to resist movement exteriorly of the respective boxes.
