Abstract
An arrangement in a range, a cooking hob or the like having at least one electrically heated hot plate (11) and/or oven, comprising a manually operable setting system (13) for the setting of a desired power or temperature for the hot plate or the oven. A detecting system (15) is arranged to detect changes in the setting of the setting system. A timing system (16 ) co-operates with the detecting system (15) to be activated by the latter. A switching system (17,26) co-operates with the timing system (16) to disconnect the power to the hot plate (11) or the oven on the reaching of an end time determined by the timing system, said timing system being reset each time the detecting system (15) is activated and then operated to start counting towards the predetermined end time.
