Abstract
A key module (110) for a keyboard is presented. The key module (110) comprises a key tappet (220). The key tappet (220) comprises a coupling portion (322) for coupling with a keycap for the key module (110). The key tappet (220) comprises at least one guiding portion (326, 328) for guiding a translational actuation movement of the key tappet (220) between a rest position and an actuated position. The key tappet (220) comprises at least one tappet stop (324) for limiting the actuation movement. The key module (110) also comprises a trigger element (350) for triggering a switch signal of the key module (110) in response to the actuation movement. The trigger element (350) is attachable to the key tappet (220). The key module (110) further comprises a module housing (230), wherein the module housing (230) is integrally formed. The module housing (230) comprises at least one positioning protrusion (334) for positioning the key module (110) and a circuit substrate of the keyboard. The module housing (230) is formed to movably accommodate the key tappet (220), in order to enable the actuation movement of the key tappet (220) relative to the module housing (230). The module housing (230) …
