Abstract
A control circuit for a vehicle seat having at least one heating element and at least one fan is provided. The control circuit includes a two-pole switch having two synchronously actuated switch elements. The switch elements are operatively connected to the heating element and the fan to operate the heating element and the fan in a first operating mode wherein only the heating element is active, and a second operating mode wherein both the heating element and the fan are active. When two heating elements are employed, the two heating elements are connected in parallel by the switch elements in the first operating mode and are connected in series by the switch elements in the second operating mode.
