Abstract

Elemento de conmutación que presenta: una primera lámina de soporte (10) sobre la que se encuentra una capa de activación (12) compuesta de un primer material resistivo y que incluye un primer terminal (16) en la capa de activación (12) para la conexión eléctrica, una segunda lámina de soporte (10) sobre la que se encuentra aplicada una capa sensora (14) compuesta de un segundo material resistivo, en el que la capa sensora (14) comprende un segundo terminal de la capa sensora (18) para la conexión eléctrica, en el que la primera y segunda lámina de soporte se encuentran separadas a una determinada distancia por medio del uso de unos distanciadores (11) y se han dispuesto de forma que la capa de activación (12) se encuentra frente a la capa sensora (14) y no se establece ningún contacto entre ellas, mientras no se accione el elemento conmutador, en el que el primer y segundo material resistivo se han escogido de forma que, al producirse un contactoentre la capa de activación (12) y la capa sensora (14), la resistencia de la capa limítrofe situada entre la capa de activación (12) y la capa sensora (14) depende básicamente del tamaño de la superficie de contacto, y en el que, al activar el elemento conmutador, se reduce, en primer lugar, a un primer punto de contacto entre la capa de activación y la capa sensora, pero que luego aumenta, al aumentar la presión ejercida sobre el elemento de conmutación, caracterizado porque la capa sensora (14) se ha configurado de modo que su resistencia eléctrica específica varía, partiendo del primer punto y en la dirección de crecimiento de la superficie de contacto, de tal forma con la distancia al primer punto, que el elemento de conmutación satisface el comportamiento de activación predefinido en función de la fuerza de compresión que actúa sobre el mismo.
