Key button, key switch, key frame and printed circuit board for a data input device, data input device and method for reducing a switching path of a key switch of a data input device

摘要

The present invention relates to a key button for a key switch of a data input device. The key button (1, 2, 3) has an actuating surface section (12) and an abutment section (20), which is coupled to the actuating surface section (12) and points in an actuating direction (A) of the key button (1, 2, 3), for abutment with a counter abutment section (56) of a resiliently movable key switch operating member (54) of the key switch, wherein the key switch operating member (54) is relatively movable to an undercut formed with the key switch or to an undercut (48; 64) adjacent to the key switch. The key button (1, 2, 3) is characterized in that the key button (1, 2, 3) has at least one latching hook (26), which is connected to the contact section (20) and extends in the actuating direction (A), having a holding section (30 ) for engaging behind the undercut (48; 64), wherein parallel to the actuation direction (A) formed between the holding portion (30) and the abutment portion (20) distance to the switch trigger resiliently biased biased holding the Tastenschaltbetätigungselements (54) in a Hintergreifungszustand of the holding portion (30) is set up.
