Abstract:
1. An alternator disconnector circuit-breaker comprising: a first switch having a first pair of contacts that are mounted to move relative to each other in translation along a first axis; a circuit-breaker second switch having a second pair of contacts that are mounted to move relative to each other in translation along a second axis, the second switch being put in parallel with the first switch; a disconnector third switch having a third pair of contacts mounted to move relative to each other; actuator means for actuating a contact of each switch; and synchronization means making it possible, while breaking, for the contacts of the first switch to separate before the contacts of the second switch separate, said contacts of the second switch themselves separating before the third contacts separate fully; said circuit-breaker being characterized in that: the actuator means of the first and second switches and the synchronization means are coupled together and comprise a cylinder mounted to move in rotation about an axis and presenting in its wall at least first and second slots that are helical in part; the actuator means of the first switch comprise at least a first slider element mounted to slide in a first slot and secured firmly to a contact of the first switch; the actuator means of the second switch comprise at least one second slider element mounted to slide in a second slot and secured firmly to a contact of the second switch.
