4weg
4weg, short for four-way switch, is a term used in Dutch-speaking electrical installations to describe a four-terminal switch used in multi-location lighting circuits. In such circuits, it is placed between two three-way switches to enable control of a light from three or more locations. The device itself does not create an on or off state; instead it reconfigures the path of current between two traveler pairs, allowing users to change which path completes the circuit.
