Key module for a keyboard and keyboard

A key module for a keyboard, wherein the key module comprises:

• a key tappet, wherein the key tappet comprises a coupling portion for coupling with a keycap for the key module, wherein the key tappet comprises at least one guiding portion for guiding a translational actuation movement of the key tappet between a rest position and an actuated position, wherein the key tappet comprises at least one tappet stop for limiting the actuation movement;
• a trigger element for triggering a switch signal of the key module in response to the actuation movement, wherein the trigger element is attachable to the key tappet, wherein the trigger element is formed as a contactor for electrically shorting contact pads of the circuit substrate of the keyboard, wherein the contactor comprises an attachment portion, by means of which the contactor is attachable to the key tappet of the key module, and wherein the contactor is integrally formed;
• a module housing, wherein the module housing is integrally formed, wherein the module housing comprises at least one positioning protrusion for positioning the key module on a circuit substrate of the keyboard, wherein the module housing is formed to movably accommodate the key tappet, in order to enable the actuation movement of the key tappet relative to the module housing, wherein the module housing comprises at least one housing stop for abutment against the at least one tappet stop of the key tappet in the rest position of the key tappet;
• and
• elastic means, with the elastic means being configured to bias the key tappet into the rest position in an assembled state of the key module.
