Abstract

The locking device uses 2 disc pairs (7,8) for respective switches, each with counter-rotating locking discs (9,10), the upper disc attached to a switch operating shaft, while the lower disc is attached to the switch shaft. The locking discs allow a relative movement between the operating shaft and the switch shaft before insertion of a locking element (4) extending between the switches.
