Abstract

A multi-contact key for providing successive contact making includes superimposed first and second insulating sheets (10, 12), each provided with a first conducting circuit (18, 22) facing each other, and an intermediate insulating sheet (16) placed between the sheets and provided with an opening (26) at the position of the conducting circuits. The sheets, (10, 12) each include a second conducting circuit (20, 24) which extends around the first circuit (18, 22), but which is electrically insulated from it while a diaphragm (28) is placed next to one of the first or second sheets and has a first protuberance (30) at the position of the first circuits (18, 22) and a second protuberance (32) surrounding the first protuberance (30) and arranged at the position of the second circuits (20, 24). The arrangement allows the first circuits (18, 22) to make before the second circuits (20, 24) when the switch is actuated. <IMAGE>
