Abstract
The arrangement for mutually locking the actuation of at least two power switches (A, B, C) has a position indicator (7) and an evaluation apparatus (10) for each power switch (A, B, C). A carrying plate (6) accommodating the position indicator (7) and the evaluation apparatus (10) is assigned to a side wall of the power switch (A, B, C). A shaft coupling (30) and a driver coupling (31) establish the connection with a switching shaft or a control shaft, respectively, of a device (32) that releases or locks the actuation of the power switch (A, B, C) when the carrying plate (6) is mounted on the power switch (A, B, C) or on a withdrawable rack (26).
