Abstract: In an electrical switch for making and breaking electric connection between an energized electric conductor and a de-energizable electric conductor that are separated by an insulator and are controllable through manipulation of a pivotably movable switch element, a grounding mechanism is provided for connecting the de-energizable electric conductor to ground potential in the open condition of the switch to pass any electric current that might flow through the insulator to ground in the event the insulator might have become defective for any reason to such extent that it allows passage of electric current therethrough. The grounding mechanism may include a grounding connector element that may be connected to ground through a suitable grounding conductor and may also include grounding contact means that establishes electrical contact with the grounding conductor element in the open position of the switch.

Abstract: A temporary guide support adapted to be removably connected to a high top insulator for guiding and transporting a wire or high voltage electrical line while it is being strung in place on its insulators. After the line is positioned on the insulators, the guide is removed and the line permanently connected to the insulators.
