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.
