| 摘要 |
The invention relates to an electrical switch which consists of an armature which can pivot against an elastic element and is arranged between a stationary and a moving support. The stationary and the moving supports are provided with contacts which are suitable for interacting with contacts mounted on the opposite sides of the armature which can pivot, in order to produce an electrical connection. The moving support is connected to a moving operating device by means of a spring. The movement play of the moving operating device is such that, during its operation, the junction point of the spring and the operating device is displaced via an unstable balance point of this spring from the one side of the junction point of this spring with the moving support to the other. This takes place in order to displace the moving support in the direction of the armature which can pivot in the direction opposite the displacement of the operating device. <IMAGE>
