Control members and use, for control purposes, of a wearable electronic communication device containing a partially-flattened flexible loop having disposed thereon non-twisting stiffening elements, an electronic unit, and push-buttons, which are positioned on the stiffening elements at such a distance from one another as to eliminate the possibility of two buttons being pressed simultaneously by the same finger, wherein the push surface of the button does not protrude above the surface of the stiffening element on which said button is located and a control signal is formed only when two buttons are pressed simultaneously. |
