Anordnung zur gegenseitigen Verriegelung von Leistungsschaltern

摘要

An arrangement for mutually locking the actuation of at least two power switches (A, B, C) has for each power switch (A, B, C) a position indicator (7) and an evaluation apparatus (10). A carrying plate (6) that receives the position indicator (7) and the evaluation apparatus (10) is associated to one side wall of the power switch (A, B, C). When the carrying plate (6) is mounted on the power switches (A, B, C) or on a rack (26), a shaft coupling (30) and a driving coupling (31) ensure the connection with a switching or controlling shaft of a device (32) that releases or lock the actuation of the power switches (A, B, C).
