Electronic switching device, particularly electronic relay, for plug-in mounting

摘要

The switch has a circuit board (20). On a first surface. this has an electronic circuit arrangement. On the opposite, second surface it has protruding cooling elements (31). The switch has a flat base (10) of insulating material. Connection lines (11) in the form of metal strips are fastened to the upper side of the base (10). The ends of the strips pass through the base (10) to its lower side and form a flat plug (12). The circuit board (20) is arranged on the base (10 standing perpendicular to its main plane. The space above the base is divided into a circuit chamber (17) containing the electric circuitry arrangement and a cooling chamber containing the cooling element (31). Connection contacts (22) of the circuit arrangement are connected near the upper surface of the base (10) to correspondingly connection lines (11). The circuit chamber (17) is closed by a cover (18) which only covers one side of the circuit board and leaves the cooling elements (31) uncovered.
