Abstract

The invention relates to an electronic terminal, in particular a communications terminal, comprising a keypad (514), which has a plurality of keys (522, 524) configured with an operating surface (534, 536). At least two keys (522, 524) are located directly adjacent to one another and guide elements (593, 594) are allocated to the adjacent keys (522, 524) on the side facing away from the operating surface (534, 536), in order to guide a key displacement, triggered by the exertion of pressure on the operating surface (534, 536), between a passive and an active position in a directed manner.
