Abstract
Contact patterns are formed on a transparent substrate to introduce information or a command into a system. A display means, responsive to the opening and closing of the contact patterns, is installed behind the transparent substrate, thereby indicating a switching condition of a switching means associated with the contact patterns.
Claims10
A switching assembly comprising:
- a. a transparent substrate having an indicating surface;
- b. a pair of transparent conductive contact patterns formed on a surface of the transparent substrate in a configuration such that the pair of contact patterns may be electrically connected with each other through an operator's finger;
- c. an electro-optical display means responsive to the opening and closing of the pair of contact patterns for altering the appearance of said switching assembly when actuated, said display means being disposed behind the transparent substrate and visible therethrough;
- and
- d. label means positioned on the indicating surface of said transparent substrate to indicate the function of the switching assembly.
