    摘要： The invention relates to a heat exchanger, especially for motor vehicles, comprising a soldered heat exchanger network made of flat pipes (2,3) and corrugated ribs (1). A liquid and/or vaporous-type medium can flow through the flat tubes (2, 3) and air can circulate around the corrugated ribs. One corrugated rib respectively comprises two surfaces (4,5) which are arranged in an essentially parallel manner in relation to each other and which are connected respectively by an arch-shaped piece (6) which is soldered to a flat pipe, said arch-shaped piece comprising three sections (6a,6b,6c) which have different curvatures.

    摘要： Switch arrangement for hearing devices, which includes a connector socket which can be covered by a socket cover. The connector socket and the socket cover are arranged and embodied such that an electrical switching contact can be produced by applying pressure to the socket cover covering the connector socket. A method for changing over programs in hearing devices with a behind-the-ear part is also specified, in which an electrical switching contact is produced by means of a connector socket of the behind-the-ear part and its socket cover. Space can be saved as a result.
