Abstract

A pushbutton mechanism for acting on an electrical contact element and comprising a pushbutton and a spring and return element with snap action characteristic can be easily and cheaply produced in that the spring element 3 consists of an elastically flexible plate or foil, namely, plastic material and preferably polyester material, having inside a cut-out 8, 9 an action surface 11 with at least two arms 12, 13 forming a bridge over the cut-out. Each arm is provided with at least one embossed hinge 14, 15, 16, 17, and the action surface 11 and the arms 12, 13 form an arch in the inactive position. In the method for production of the spring and return element with snap action characteristic, one first punches out the holes 8, 9, bounding the action surface 11 with the arms 12, 13, and then one performs an embossing in the transverse direction in at least one location on each of the arms, whereby the material flows in the lengthwise direction of the arms to form the hinge sites and to lift up the action surface and its arms. <IMAGE>
