The invention relates to a switch and/or circuit breaker incorporating various cut-off poles that can be connected in series to reduce the cut-off voltage. The electric breaker switch comprises two groups of fixed contacts and a group of moving contacts able to move between an electrical cut-off position and an electrical closure position in which, and it incorporates at least one integral part made of a conductor material forming two fixed contacts of the same group of contacts, connecting the poles of the switch associated with said contacts in series. As a result of said integral part, several poles are more effectively and more safely connected in series, preventing excessive overheating of the terminals and possible switch failures. |
