<p>The invention provides a device (11) for switching an electric heater (12) with at least two heating areas (25, 27, 29), which can be variably supplied with electric power by at least one power setter (22) and having control means (19) for the at least one power setter (22, 23) and with functionally separate switching means (14, 16) for operating the at least one power setter. On operating a first switching means (14), a heating area (27) associated therewith can be set by means of a power setter via the control means and on operating a further switching means (16) a heating area (29) associated therewith is settable by means of a power setter. Preferably, precisely one heating area (27, 29) is associated with each switching means (14, 16). The heating areas can be areally extensive heating zones or different power levels of a heater.</p> |
