Abstract: A contacting unit for a card-shaped carrier element of electronic components has a housing with a base plate and a contact field provided at a side of the housing leading when inserted into a computing device. A PCMCIA card is placed into the housing parallel to the base plate such that between the base plate and the PCMCIA card an insertion channel for a chip card is formed. The housing has an insertion slot for inserting a chip card into the insertion channel. The insertion slot is arranged opposite the contact field. Contact elements are connected to a face of the PCMCIA card for contacting the chip card inserted into the insertion channel. An insertion guide surrounds the insertion slot. The insertion guide has lateral cover portions extending to the leading side of the housing. Abutments are connected to the housing in the vicinity of the contact field for limiting an insertion depth of the chip card into the insertion channel.

Abstract: A manually actuatable electric pushbutton switch that automatically returns to the starting position after actuation, especially such a switch for the keyboard of an electronic device, for example a typewriter, is provided. The switch has a plastic housing in which is disposed a plate spring that is in engagement with an actuating button. The plate spring has a region that during shifting of the actuating button and flexing of the plate spring abruptly jumps to a different position when the electrical contact position is achieved, so that the triggering function is indicated both physically as well as audibly to the user. The region of the plate spring that abruptly reverses is preferably formed by slots, between which the abruptly reversing plate spring strip is defined.

Abstract: A display contact arrangement for the contacting of electrical contacts of a display element, for example, for a strip-shaped LCD display or a planar-shaped LCD monitor, with the corresponding electrical contacts of a circuit board via an insulator body. The rigid strip-shaped plastic insulator body, in its longitudinal direction, has arranged alternatingly and staggered on each side wall leaf springs serving as electrial leads. The display element rests on the upper bent ends of the leaf springs, thereby making contact. The leaf springs are connected to the electrical leads of the circuit board either by SMD technique or by soldering.
