The housing (10) of an electrical device, in particular a switching and control device for motor vehicles, includes an upper shell (11) and a lower shell (12), and PC boards (15, 25) are located in both shells (11, 12). The required power components (17) are distributed to both PC boards (15, 25). The lower shell (11) of the housing (10) has side walls (16) encompassing three sides. The upper shell (11) has, in addition to the outer rim (21) extending around three sides, a protrusion (22) protruding into the housing on two opposed sides, so that a space (23) is created between the rim (21) and the extension (22). In the assembled state, the side wall (16) protrudes into the space (23) in the other shell (12). The power components (17) rest on the inner wall of the side wall (16) or of the extensions (22), so that the lost heat can be dissipated in a simple way.
