Abstract
An electrical contact arrangement is disclosed for a battery-operated instrument, especially a battery-operated clock having a housing made of synthetic material such as plastic. Two contact elements are provided for connecting two terminals of the battery with two respective paths of a circuit board. One of the contact elements comprises a bus fastened to the plastic housing, and several 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 with a first portion bearing against a wall of the housing and a second portion bearing against the circuit board, the latter having been inserted into the housing parallel with such wall. The second portion of the contact engages an appropriate path of the board.
