Abstract
A functional component having a button function includes a support component, a film, and an electrical switching element. The support component has a recess. The film covers the recess. The electrical switching element is situated below the recess and is actuatable by pressure being exerted on the film in the area above the recess. A ring-shaped or hollow cylindrical body is situated along an inner edge surface of the recess and is in contact with the film.

A functional component having a button function, comprising:
- a support component having a recess;
- a film that covers the recess;
- an electrical switching element situated below the recess, the electrical switching element is actuatable by pressure being exerted on the film in an area above the recess;
- and
- wherein a ring-shaped or hollow cylindrical body is situated along an inner edge surface of the recess and is in contact with the film.

A functional component having a button function, comprising:
- a carrier having a recess, wherein a periphery of the recess is surrounded by an edge surface of the carrier;
- a film arranged on the carrier and covering the recess;
- an electrical switch arranged within the recess and below the film, the electrical switch including a mechanically actuatable switching element;
- wherein the film arches into the recess, and thereby causes the switching element to actuate, in response to pressure exerted in an area of the film above the recess in a direction toward the recess;
- and
- a deformable body arranged within the recess along the edge surface of the carrier and in contact with a portion of the film, the deformable body elastically supporting the film at the periphery of the recess.
