Abstract: An electronic assembly has a circuit board and two or more heat sinks arranged on the printed circuit board, each having a straight air duct section from an air inlet opening of the heat sink to an air outlet opening of the heat sink. The heat sinks are spaced apart from each other one behind another in a row by intervening spaces, with their air duct sections lying in a straight line and forming an air duct. Through-hole-mounted THT components, which in each case rest against an outside surface of one of the heat sinks, have connecting pins secured in the printed circuit board. A fan generates an air stream that enters the air inlet opening of the heat sink that is located at the beginning of the row and flows through the air duct.

Abstract: An electromechanical switching device is disclosed for protecting electrical wires and/or consumers. In at least one embodiment, the device includes at least one thermal triggering element and at least one switching device-internal heat source. For the at least one thermal triggering element, the electromechanical switching device includes a thermal coupling of at least one of the switching device-internal heat sources. At least one embodiment of the invention also relates to the use of a thermal coupling.
