Abstract
The present invention includes a flexible, pressurizable keyboard made of resilient layers of plastic material, with molded keys which are deformable when pressed so as to send a signal to an electrical device. The keys are arranged with a flexible electrical circuit thereattached, which when depressed, establish a proper complete circuit.
Claims6
A data entry panel arranged for entry and sending of electrical signals therefrom, comprised of:
- a first layer of flexible material;
- a second layer of flexible material with a fluid pressurizable cavity arranged between said first layer and said second layer of flexible material;
- a flexible conductive circuit disposed between said first and second layers of flexible material, wherein flexure of at least one of said layers causes said circuit to generate a particular electrical signal, which signal is transmitted from said panel.
