SWITCH INCORPORATING NCAP LIQUID CRYSTAL

摘要

A switch comprising a liquid crystal means disposed between two flexible substrates each having an electrode formed thereon. Each of the substrates have sufficient flexibility to deflect in response to the application of a pressure thereto. The display is visible through the substrate located at the front of the switch. A third substrate is disposed to the rear of the first two substrates and has a conductor formed thereon. The third substrate forms part of a switch and includes a flexible portion for actuating a switch function in response to the application of the pressure. A reflector means is formed on the side of the third substrate remote from the conductor. An air gap exists between the reflector means and the second electrode. A substantially rigid substrate is disposed to the rear of the third substrate. At least a portion of the first, second and third substrates are deflectable toward the rigid substrate in response to the application of a pressure so as to actuate the switch function and cause a change in the display.
