Control means of a wearable electronic communication device for control purpose and use thereof are claimed. The wearable electronic communication device comprises a flexible loop being at least partly flattened and comprising non-twistable rigid members; an electronic unit; and push buttons disposed on the rigid members at such a distance from each other so as to avoid possibility of pushing two push buttons simultaneously with one finger, wherein the push surface of each push button does not project beyond the surface of the rigid member bearing the push button, and a control signal is generated only when two push buttons are pushed simultaneously.
