Abstract: An electronic device includes a microprocessor connected to an input keyboard comprising primary conductive lines connected to primary areas and to a terminal. It further includes first, second and third secondary conductive lines connected to secondary areas and to a terminal. It further includes input keys each of which, when operated, establishes contact between a primary area of a primary line and a secondary area of a secondary line to place each of these two lines in a high state.

Abstract: A portable communication device with an external housing (1) containsat least a mechanical switch (2a; 2b) and at least one key (3) for actuation of said mechanical switch (2a; 2b), said key comprising an actuation surface (30) which protrudes from said external housing through an aperture (10), and the mechanical switch being able to be actuated by swiveling of the key (3) around an axis (XX?) substantially perpendicular to said actuation surface. According to the invention said key is made of plastic material and comprises, in its thickness and behind said actuation surface, at least one emerging slit (31a; 31b) extending substantially parallel to said actuation surface.

Abstract: The present invention relates to an electronic device comprising a casing containing a printed circuit (50) and comprising a front face (10) and a rear face (20), and a removable keypad module (40) electrically connected to the printed circuit (50). According to the invention, the device further comprises a removable clip (60) that encloses the perimeter of the keypad module (40) in order to lock the keypad module to said front face (10).

Abstract: The present invention provides a device for latching and unlatching a removable cover referred to as a “removable element” on a box referred to as a “fixed element”, the device comprising a latch provided on one of the elements and slidable between a latched position in which one end of the latch is in contact with the other element and unlatched position in which said end is not in contact with the other element, said latch having a gripping surface enabling it to be caused to slide. According to the invention, it has means for locking the latch in the unlatched position, at least until the cover is moved.
