ABSTRACT:
A contact arrangement for a battery-operated instrument, especially a battery-operated clock, having a housing made of synthetic material. Two contact elements are provided for making connection between the two terminals of a battery and two respective paths of a circuit board. One of the contact elements includes a bus portion fastened to the housing, and a pair of legs. A first leg makes contact with one terminal of the battery and the second leg makes contact with a path of the circuit board. The second leg is designed in the form of a knife-edge contact, one portion thereof bearing against a wall of the housing, and another portion thereof bearing against the circuit board. The second leg thus holds the circuit board in its inserted position by mechanical force. The contact element further includes a third leg which electrically contacts as well as mechanically clamps a small bulb when the latter is inserted into the housing.
