Title: Compact electrical device, especially a switched-mode power supply

Abstract: The invention relates to A compact electrical device, especially a switched-mode power supply, comprising a transformer for matching different electrical voltages, and an electrical circuit and a plug-in device, which can be connected to a reference voltage, at least one primary winding of the transformer being connected to the plug-in device and at least one secondary winding of the transformer being connected to the electrical circuit via conductor tracks, the primary and secondary windings enclosing at least a part of a transformer core. In a compact electrical device which provides for reduction in the assembly expenditure and, nevertheless, operates reliably, the primary and the secondary windings (3) are arranged jointly with the conductor tracks (2) and/or the plug-in device (4, 5) in a carrier body (1) made of insulating material, the primary and secondary windings (3) being insulated from one another by the material of the carrier body (1) and the electrical circuit arranged on a planar carrier element being connected to the conductor tracks (2) of the carrier body (1) via an electrical connection.
