The invention relates to a shift-control housing, a switch case with a housing body for instance. The housing body is provided with an air conditioning device in the area of a side wall (10). Said air conditioning device has a heat exchanger (20). At least one fan (33) is fixed to the heat exchanger (20). The fan conveys air from the inner chamber of the shift-control housing to inner air guiding channels (28, 2) of the heat exchanger. The aim of the invention is to simply construct such a shift-control housing that can have different cooling performances. To this end, the heat exchanger is embodied as an air-to-air heat exchanger which is provided with outer air guiding channels (28, 1) that are spatially separated from the inner air guiding channels (28, 2). The heat exchanger is provided with end sections in the area of the lateral ends of the outer and inner air guiding channels. Collar housings (30) can be fixed to said end sections. The fans (33) are held at the collar housings.
