Abstract
An apparatus is disclosed for mutual interlocking of two switches, in particular circuit breakers. In at least one embodiment, the apparatus includes two plungers which each engage in one of the two switches and can be moved in the plunger longitudinal direction, wherein, when one switch is being switched on, the plunger which engages in this switch is moved by pivoting of a control disk from its nil-point position to its opening position. In at least one embodiment, the apparatus includes a blocking device which blocks pivoting of the other control disk by moving the plunger to its opening position. In order to achieve a maintenance-free apparatus, in at least one embodiment it is proposed that at least one blocking element of the blocking device is moved by the plunger when this plunger is being moved to its opening position, such that pivoting of the other control disk with respect to the other plunger, which is located in the nil-point position, is blocked.
