A pressure sensitive switch has upper, middle and lower laminar elongated members, the middle member having an opening therethrough defining a cavity between the upper and lower members. A first array of substantially parallel, spaced-apart electrically conductive bands is fixed to a lower surface of the upper member and traverses the cavity. A second away of substantially parallel, spaced- apart electrically conductive bands is fixed to an upper surface of tire lower member and traverses the cavity. Selected lower member bands are discretely connected to an electrical input lead and other lower member bands are discretely connected to an electrical output lead. An array of substantially parallel, spaced-apart dielectric bands narrower than the conductive bands is fixed to one of the lower and upper members and traverses the cavity between the arrays of conductive bands at alternate overlapping points thereof and partially separates the arrays of conductive bands from electrical contact therebetween at said alternate overlapping points. The upper and lower members are resiliently flexible to permit the overlapping points of the arrays of conductive bands to close into and open out of electrical contact therebetween upon exertion and removal, respectively, of a threshold external compressive force to the cavity.

Interrupteur sensible à la pression présentant des éléments laminaires allongés supérieur, médian et inférieur dont le médian est traversé par une ouverture constituant une cavité entre le supérieur et l'inférieur. Une première série de bandes conductrices espacées et sensiblement parallèles, fixée à la surface inférieure de l'élément supérieur, traverse la cavité. Une deuxième rangée de bandes conductrices espacées et sensiblement parallèles, fixée à la surface supérieure de l'élément inférieur, traverse la cavité. Certaines bandes de l'élément inférieur sont reliées individuellement à une source électrique. Une rangée de bandes diélectriques plus étroites que les bandes conductrices, espacées et sensiblement parallèles et fixées soit à l'élément inférieur, soit à l'élément supérieur, traversent la cavité entre les rangées de bandes conductrices en des points de recouvrement alternant et empêchent partiellement les rangées de bandes conductrices d'entrer en contact entre elles auxdits points de recouvrement. Les éléments supérieurs et inférieurs sont élastiques pour permettre aux points de recouvrement des rangées de bandes conductrices d'établir ou de rompre un contact électrique entre elles selon qu'on exerce ou relâche une force de compression seuil extérieure sur la cavité.
