摘要

The housing (3) is made of die-cast metal for receiving and supporting a printed circuit board (7). The housing has a deep circumferential groove (14) formed on a projecting edge (15) to which a metallic cover (9) is set. The cover is arranged partially resting against the electronic components (5,6) or pressed against a heat dissipation surface (4) in the housing.
