Abstract (en)
[origin: WO8701236A1] The module is provided with a leaf spring arranged diagonally across the key housing on its underside, the spring being deformed by a key push-rod to operate a contact foil. A free end of the spring is inserted in a recess open at the top and allows adjustment of the spring by compression of the free end or of the underside against the part of the spring adjacent to the curved end. By suitably deforming the free end the spring can be held in a self-locking manner in each support position in the recess. To regulate the actuating force a cylindrical compression spring is provided inside the key push-rod, the latter pressing against a post running over the leaf spring.
