Abstract
An electronic circuit having two states, at least one of which is stable and which permits information to pass from one terminal to the other. The circuit can be activated by the flow of a minute electric current through the human body. The circuit is particularly suitable for any hand-held instrument such, for example, as an electronic calculator watch of the digital type and including electronic logic. It permits to activate certain functions or to carry out certain calculations by activating a conductive surface by means of a hand-held metallic pin or the like. This makes it possible to provide a large number of functions or operations and to display numbers say on the face of a watch and to activate each one by touching it with a pin held by the wearer of the watch or instrument.
