| 摘要 |
The invention provides a switch comprising a switch unit which delimits a cavity in which a fixed contact (38, 148) and a point-like central fixed contact (40, 150) are arranged and which accommodates a tripping device, characterized in that the lateral fixed contact (38, 148) and the central fixed contact (40, 150) are produced by cutting, from the same sheet (160) of conducting material, two longitudinal strips (38, 40), the lower faces (164, 175) of which are coplanar, in that the middle part of the central fixed contact strip (40) which includes the point-like central fixed contact (150) is bent vertically downwards in order to offset, vertically downwards, the central contact (150) with respect to the lateral contact (148) and in that the free connection ends are produced by bending after overmoulding of the support (100) made of insulating material.
