Abstract

An information panel assembly comprised of liquid crystal display devices, positioned on a mounting member and sandwiched between a cover member and a circuit member. Elastomeric connectors connect the liquid crystal display devices to drive circuitry on the circuit member. The cover member includes rear projecting members which are accepted by apertures on the circuit member and are disposed to engage threaded fasteners, locking the assembly together. A switch member including a matrix of membrane switches is mounted over the cover member connecting each switch to the circuit member thereby, selectively controlling the information displayed.
