    Abstract: A first switch (10) has a first pair of contacts (12, 14) that are mounted to move relative to each other in translation. A circuit-breaker second switch (20) has a second pair of contacts (21, 24) that are mounted to move relative to each other in translation, the second switch (20) being put in parallel with the first switch (10). A disconnector third switch (30) has a third pair of contacts (32, 34) that are mounted to move relative to each other. Synchronization means (50, 50′) make it possible, while breaking is taking place, for the contacts of the first switch (10) to separate before the contacts of the second switch (20) separate, the contacts of the second switch themselves separating before the third contacts (32, 34) separate fully. The synchronization means are actuated by a servomotor (40).
