A hairpin strip-spring has one end which acts on the click and another end which acts on the lever. One of the frame elements comprises an elongated recess and the other of the frame elements comprises a notch having edges partially covering the recess. The hairpin strip-spring is inserted in the recess through the notch. The lever and the click are not subjected to the action of the hairpin strip-spring assembly.
