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.
Claims15
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;
- 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;
- and
- wherein the electrical switch further includes a circuit board, a switching plunger, and a switch housing for guiding the switching plunger, the switching element resting on the circuit board, and the switching plunger being in mechanical contact with the switching element and with the film;
- and
- the film when arching into the recess moves the switching plunger toward the switching element whereby the switching element actuates.
