Abstract
A key module includes an actuation element with a cam nose and a contactor unit with a contact nose movable in the direction of the movement axis and transverse to the direction of the movement axis. Also, a contact element is formed and arranged for establishing electric contact with the contact nose. Moreover, the housing element accommodates the contact element, the contactor unit and the actuation element, wherein the actuation element and/or the cam nose includes a constructive element formed to deflect the contact nose from a rest position adjacent to the contact element in the direction along and/or transverse to the movement axis upon a defined movement of the actuation element, then abruptly release it so that the movable contact nose returns to the rest position and strikes the contact element and/or the housing element. Electric contact with the contact element is established and acoustic noise is produced.
