Abstract

A method and arrangement for entering a switching program into an electronic timer, in particular a kitchen range timer, wherein the switching program consists of at least one switching cycle within a predetermined time range, preferably within 23 hours and 59 minutes. The switching cycle is timely defined through any two of three entities consisting of switching cycle-start, switching cycle-period and switching cycle-end, wherein the entry is effected serially in the form of sequential input pulses, which have an information relative to the setting direction (forward or backwards) associated therewith, and which is preferably counted in a forward-backward counter arrangement. The entry of a first entity for the definition of the switching cycle is limited to a time interval between the actual time and the end of a pregiven first program range, in which upon the entry of the entity switching cycle-start or switching cycle-end there is set with the first input pulses the present entity to a starting value most closely to the present limit of the first program range but within the first program range, and wherein upon the entry of an input pulse with an associated setting direction w…
