Abstract
An electrical switchgear apparatus comprises a plug-in circuit breaker movable in a fixed frame by means of a drive mechanism. A movable element, secured to the circuit breaker or to the drive mechanism, takes indexed positions characteristic of the plugged-out, test or plugged-in state of the apparatus. The apparatus is provided with at least two indicating switches. Indexing means enable each of the switches to be connected to the movable element in such a way that the first switch switches when the movable element reaches a first indexing position and that the second switch switches when the movable element reaches a second indexing position. The same indexing means, placed in a second state, also enable each of the switches to be connected to the movable element in such a way that the first switch switches when the movable element reaches the second indexing position and that the second switch switches when the movable element reaches the first indexing position.
