Abstract

An electric, particularly battery-operated timing clock which includes electric time setting components for an electrical switching device arranged about a clock dial. A signal emitter is adapted to be actuated by the switching device. In order to actuate the signal emitter at preselectable time periods, a contact switch element which rotates about the hour-hand shaft of the clock forms, through a contact path and a slide contact, one pole of the switching device, the other pole of which is formed by an electrically-conductive segmented ring with radial segments. Each segment includes a free end actuatable through a latchable setting component, and a contact finger which projects into the path of movement of the contact switch element upon actuation of the free end.
