The invention relates to a locking device to prevent from several switching devices from being activated by purely mechanical parts which ensure that the switching devices remain locked in the case of power failure. The invention seeks to provide a locking effect involving little expenditure of force, irrespective of component tolerance wherever possible. To achieve this, both a locking disk (17a) which is coupled to the shaft of the switching device (2a) and a pivoting locking member (18a) are assigned to one switching device (2a) and are respectively connected to a locking member (18) or a locking disk (17b) assigned to the other switching device (2b) in a crosswise manner by means of a connecting element (11a; 11b). When one locking disk (17a; 17b) is rotated, the other locking member (18b; 18c) pivots and interlocks with a section of the locking curve (25b; 25a) of the pertaining locking disk. |
