Circuit assembly for a switched-mode power supply of an electric auxiliary device at the site of a connected electric load, building data processing device, socket module, and electric stairwell installation

A socket module, comprising:

• a circuit assembly for switched-mode power supply of an electric auxiliary device at a site of a connected electric load which is located in a circuit in which a switch element switches an operating state of a load with low loss, while the auxiliary device is continuously supplied with electrical energy, the circuit assembly comprising
• at least one bridge component arranged in parallel circuit with respect to the switch element;
• at least one support component connected upstream of the electric load such that the electric load is supplied with power as a function of a switch position of the switch element;
• and
• at least one auxiliary device, arranged between the at least one bridge component and the at least one support component, configured so that the at least one auxiliary device is supplied with power without interruption regardless of the switch position of the switch element,
• wherein the at least one bridge component has at least one cyclically conductive switch element and the at least one support component has at least one anti-cyclically conductive switch element and a storage element, and
• wherein the socket module has two mechanical interfaces configured so that the socket module is arrangeable between a wall or ceiling and a wall or ceiling luminaire.

An electrical stairwell installation, comprising:

• a circuit;
• and
• a circuit assembly for switched-mode power supply of an electric auxiliary device at a site of a connected electric load which is located in the circuit in which a switch element switches an operating state of a load with low loss, while the auxiliary device is continuously supplied with electrical energy, the circuit assembly comprising
• at least one bridge component arranged in parallel circuit with respect to the switch element;
• at least one support component connected upstream of the electric load such that the electric load is supplied with power as a function of a switch position of the switch element;
• and
• at least one auxiliary device, arranged between the at least one bridge component and the at least one support component, configured so that the at least one auxiliary device is supplied with power without interruption regardless of the switch position of the switch element,
• wherein the at least one bridge component has at least one cyclically conductive switch element and the at least one support component has at least one anti-cyclically conductive switch element and a storage element.
