摘要： A blocking mechanism is used for switching devices. The manual control element of the blocking mechanism can be locked against unauthorized actuation. The blocking mechanism is able to be blocked such that it cannot be detached. Retaining elements can be moved in relation to each other in a guide, and can engage with retaining lugs in recesses of a switching device to be locked. A catch element locks the actuation of the retaining elements in predetermined retaining positions in its engaged position.
