Key module

A key module comprising:

• an actuation element comprising a cam nose, wherein the actuation element is supported to be movable along a movement axis in a housing element;
• a contactor unit with a contact nose movable in the direction of the movement axis and transverse to the direction of the movement axis;
• a contact element formed and arranged for establishing electric contact with the contact nose;
• and
• the housing element for accommodating the contact element, the contactor unit and the actuation element,
• wherein the actuation element and/or the cam nose comprises at least one 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 the contact nose so that the movable contact nose returns to the rest position and strikes the contact element and/or the housing element, wherein electric contact with the contact element is established and acoustic noise is produced
• wherein the contactor unit has, in a region of the contact nose, a strike portion formed to strike the contact nose on at least one portion of the housing element, in particular wherein the strike portion comprises a surface oriented substantially parallel to the at least one portion of the housing element and/or wherein the strike portion is formed by an angled part of the contactor unit.
