摘要

A metallic wiring carrier (1) is stamped or etched to form a two-dimensional structure with conductive tracks for electrical interconnection of a transistor switch (2), an electronic switching circuit (4), passive components (5) such as a resistor and capacitor for interference suppression, connection tags (7a-7d) and heat sinks (3a, 3b). The tags are shaped to conform to the type of pluggable contact typically used in the motor-car industry, and therefore compatible with contacts provided for an electromechanical load switch. The piece parts of the wiring carrier may constitute electrical resistances.
