PCT No. PCT/SE87/00539 Sec. 371 Date Jul. 14, 1988 Sec. 102(e) Date Jul. 14, 1988 PCT Filed Nov. 17, 1987 PCT Pub. No. WO88/04027 PCT Pub. Date Jun. 2, 1988.A contact device for delivering electrical signals corresponding to the movement of a movable body having two opposing layers including a base layer and a flexible layer spaced from the base layer. An electrical input conductor attached to one of the two layers and is electrically connected to a power source. The device also includes an electrical output conductor attached to one of the layers for transmitting an electrical signal when the output conductor is electrically connected to the input conductor. A plurality of contact elements are attached to one of the layers for electrically connecting the input conductor to the first output conductor. A pressure device attached to the movable body moves along a path defined by at least one of the conductors, abuts the flexible layer and displaces the flexible layer toward the base layer. Thereby, the input conductor and the output conductor are electrically connected by means of at least one of the contact elements, whereby an electrical signal is generated in the output conductor when the pressure device displaces the flexible layer toward to base layer. |
