Abstract: A miniaturized housing or display device including at least one electric circuit adapted to be connected to an electric current supply. The electric circuit includes at least one switch. The housing further is adapted to receive a mechanical alarm clock that has a movement winder and an alarm winder. A counterweight is attached to hang from each of the winders such that each of the counterweights abuts against a corresponding switch in each of the circuits when the mechanical alarm clock is inserted in the compartment and the counterweights descend as a result of the movement of each of the winders.
