Abstract

Eine Membran (14), die an ihrem Rand (16) eingespannt ist, hat ein flaches Mittelfeld (18) sowie eine zwischen diesem und ihrem Rand (16) angeordnete Rollfalte (20). Durch einen auf die Membran (14) einwirkenden Druck sind drei Schalter (36, 36′, 36″) betätigbar. Zur Übertragung der durch den Druck auf die Membran (14) hervorgerufenen Betätigungskräfte auf Koppelpunkte (32, 32′, 32″) an je einem der Schalter (36, 36′, 36″) ist eine Stützplatte (22) vorgesehen. Das Mittelfeld (18) der Membran (14) ist nur gemeinsam mit der Stützplatte (22) zum Rand (16) der Membran (14) verschiebbar. Die Stützplatte (22) ist an den Koppelpunkten (32, 32′) zweier Schalter (36, 36′) derart kippbar abgestützt, daß die durch das Mittelfeld (18) und einen daran angrenzenden Teil der Rollfalte (20) definier­ te wirksame Fläche der Membran (14) sich bei Betätigung eines dieser beiden Schalter (36, 36′) zum anderen dieser beiden Schalter hin verlagert. Damit wird erreicht, daß diese beiden Schalter (36, 36′) auch dann mit Sicherheit in einer bestimmten Reihenfolge schalten, wenn ihre Schaltdrücke sich nur geringfügig voneinander unter­ scheiden. A membrane (14) which is clamped on its edge (16), has a flat midfield (18) and one between them and its edge (16) arranged roll fold (20). By a pressure acting on the membrane (14) is three Switches (36, 36 ', 36 ″) can be actuated. To transfer the caused by the pressure on the membrane (14) Actuating forces on coupling points (32, 32 ', 32 ″) each one of the switches (36, 36 ', 36 ″) is a support plate (22) provided. The middle field (18) of the membrane (14) is only together with the support plate (22) to the edge (16) of the Membrane (14) slidable. The support plate (22) is on the Crosspoints (32, 32 ') of two switches (36, 36') such tilted supported that by the midfield (18) and define an adjacent part of the roller fold (20) te effective area of the membrane (14) when actuated one of these two switches (36, 36 ') to the other of these relocated to both switches. This ensures that these two switches (36, 36 ') even then with certainty switch in a certain order if their Switching pressures differ only slightly from each other divorce.
