Switch Blocking Pins

The Switch Blocking Pin is a non-conductive pin that is placed into the switch blocking location of an air break / load break switch when the switch is opened for work on the line or equipment. The blocking pin assures the worker that the switch stays open until the pin is removed. It completely blocks the switch from operating due to human error, vibration, wind or any other undesirable actions that would cause the switch to close.


Switch Blocking Pin Features

  • The pins can be placed into the switch blocking location of Omni-Rupter® and Scada-Mate® switches
  • Can be installed by one worker from the ground using an extension hotstick, keeping the worker away from energized conductors and equipment
  • Switch cannot be closed until the pin is removed
  • A hold card or tag can be attached to the pin to easily locate the open switch

Omni-Rupter® and Scada-Mate® are registered trademarks of S&C Electric Company, Chicago, IL.
