Abstract :
A new type of touch switch based on the standard liquid-crystal display cell has been developed. The switch, which responds to slight finger pressure, overcomes many of the problems associated with conventional touch switches. The letter describes the operating principle, realignment due to liquid flow, and reports measurements of switch sensitivity.
