<p>The invention relates to a device for interrupting electrical current, such as a switch-disconnector, comprising a case (1), a stationary contact (21), a sliding carriage (3) carrying a mobile contact (22), actuating means (5) to move the carriage by making the mobile contact near the stationary contact, and retaining means (6) to transitorily retain the carriage in a position for which the stationary and mobile contacts are separated from each other while the actuating means compress a spring, then to suddenly free the carriage and make it possible for a reciprocal pressing of the stationary and mobile contacts. According to the invention, the retaining means comprise a case shoulder (61) and a pawl (62) pivotally mounted on the carriage (3), the pawl cooperating with the shoulder in order to retain the carriage during the compression of the spring, and being subjected to a swiveling making it possible for it to move away from the shoulder once the spring is sufficiently compressed.</p> |
