seinakontakt

Seinakontakt, also known as a wall socket or electrical outlet, is a device that allows electrical equipment to connect to a power supply. In its most common form, it features openings into which a plug can be inserted. These openings are connected to the building's electrical wiring, providing a controlled point of access to the alternating current (AC) power distributed throughout the structure.

The design of seinakontakt varies significantly by region due to differing electrical standards and safety regulations. These variations include the number of pins or holes, their shape, spacing, and the voltage and frequency of the power supplied. Common types include those with two or three holes, with the third hole often serving as a grounding connection for enhanced safety.

Seinakontakt are essential components of modern electrical infrastructure, enabling the operation of a vast array of appliances, electronics, and tools. They are typically installed on walls, baseboards, or other surfaces to make them accessible for use. Safety features such as shutters or insulated openings are incorporated into many designs to prevent accidental contact with live electrical parts. Over time, the technology and safety standards for seinakontakt have evolved to meet increasing demands for convenience and protection.
