The invention relates to a medium- or high-voltage switch (10) comprising: - a secondary vacuum chamber (111); - a first and second contact (121, 122), mounted such as to be movable relative to one another in the chamber (111) between an open position, wherein the first and second contacts (121, 122) are not connected to each other, and a closed position, wherein the first and second contacts (121, 122) are in electrical contact with each other. The switch (10) also comprises a conductor (210, 220, 230) that is arranged in the chamber (111) such that there is a pressure threshold in the chamber (111) beyond which partial discharges are generated by said conductor, at least when the first and second contact (121, 122) are in the closed position, and such that the high or medium voltage is applied to said switch (10). The invention also relates to a switch assembly and to a method for testing such a switch. |
