Description

TECHNICAL FIELD

The disclosure generally relates to a modular switching assembly.

BACKGROUND

Electric equipment, such as an outlet, switch, or operating element, provides an interface to an electrical network of a house. According to the conventional technology, such electric equipment is self-contained and independent. Each electric equipment has a fixed function. For instance, an electric equipment for light switches is distinct from an electric equipment for intermediate switching.
With the line or current conductor of the electrical network permanently connected to the electrical equipment, a trained specialist is necessary in case the electric equipment or its function needs to be installed, updated or changed. Also, the entire electric equipment needs to be replaced. Thus, updating or replacing electric equipment comes with expenditures regarding human and material resources.
