| 摘要 |
The invention proposes an electrical apparatus (10) comprising a main moving contact (14) and a secondary moving contact (16), which are able to move along the main axis A of the apparatus (10), in which the main moving contact (14) is linked to the secondary moving contact (16) by way of a return mechanism (20) which transforms the movement of the main moving contact (14) in one direction into a movement of the secondary moving contact (16) in the opposite direction, characterized in that the return mechanism (20) comprises two levers (22, 24) mounted pivotably with respect to the fixed frame (12) about respective parallel pivoting axes (B, C), each lever (22, 24) of which is linked to the main moving contact (14) or to the secondary moving contact (16) on the one hand and to the other lever (24, 22) on the other hand. |
