Abstract: An illuminated, waterproof and dust-proof switching element for converting a linear movement of a push button into an electrical switching signal, has a housing and a cap which is axially displaceable within the housing along a stroke path between two end bearings. The cap has a protective membrane for external sealing that is formed from a flexible plastic material by way of multicomponent injection molding. The switching element includes within the housing at least four contacts, a pressure compensation element, a circuit board on which at least one push button and at least two lighting elements are arranged, a silicone pad as a restoring element, a guide, an end stop, a cap with integrally molded protective membrane, and a frame. At least two pairs of the contacts have a like contour including a linear arrangement in the region of a plug and rectangular arrangement in the interior.

Abstract: A door opening circuit comprises pipe-shaped housing and a button which can be moved axially in a housing in order to actuate a circuit component connected to the housing. The button is held in a rest position by a force and can be pushed in a direction opposing said force. Perpendicular to the push path of the bottom and pivotable about a pivot mount. A lever is provided perpendicular to the push path of the button and pivotable about a pivot mount. The lever acts upon a circuit component from a position at a distance to the pivotal mount, whereby the button impinges upon the lever between the pivotable mount and the aforementioned position. Another button is located concentrically to the first button on the reverse side of the housing. The pivotal mount is provided with a lever element. The lever can be moved in the direction of the housing longitudinal axis towards the first button.
