    Patent number: 5006681
    Abstract: A leaf spring system, in particular for influencing a least one body operating or comprising one or more contacts of an electric switch, with a frame aperature and at least one leaf spring which can act on the at least one body. The leaf spring system comprises a supporting frame for receiving the leaf spring in the frame aperture thereof. The spring is supported at one end and has another projecting free end whereby the one body to be influenced by the spring action is accommodated between this other end and the supporting frame. The dimension of the body in the frame aperture is greater than the distance between the edge of the supporting frame and the free end of the at least one leaf spring when the latter is situated essentially in the plane of the supporting frame. The supporting frame is secured against movement relative to the leaf spring and body. The invention further relates to electric switches provided with such a leaf spring system.
