ABSTRACT:
A device to prevent inadvertent closure of switches. The device includes a horizontal blocking member and in some embodiments an optional vertical blocking member. The device attaches to a rotary element in communication with the switch such as an operating pipe and prevents closure of the switch by striking structural components in the area of the switch as the pipe rotates. The device is of particular application with respect to high-voltage and extra high-voltage switches as typically employed in electrical transmission and distribution substations.
