Abstract

A key set is described, for making contact with an electronic apparatus, for example a video recorder. The special feature of this key set, which may have one or more keys (3), is that it is produced integrally as a plastic injection-moulded part with all the individual elements such as the key (3), the contact plunger (5), the web (7), the hinges (9, 9') and the support (8). The key set (1) is connected by means of the support (8) to an apparatus housing (2) or apparatus chassis such that the push button switches (11) which are arranged on a printed-circuit board (10) mounted in the apparatus can be operated by means of the contact plunger (5). The key set is furthermore designed such that it can be mounted in the apparatus with the minimum labour cost, for example automatically. <IMAGE>
