ABSTRACT:
An electronic timer, preferably a kitchen range timer, which includes a control circuit, a display area, input elements, and a switching arrangement which selectively connects an appliance (auto mode) which is operable through the timer directly with a current supply (manual mode). The control circuit is switched into the auto mode through the input of at least one complete switching term, whereby after traversing of the switching terms in the control circuit, the latter is switched into a wait-mode, wherein the appliance which is already separated from the current supply, remains separated from the current supply, and wherein the control circuit which is connected in the wait-mode is switched back into the manual-mode upon the actuation of the manual input element which is provided for this purpose.
