Multiway switching#More than two locations

A cross switch (also called Rev. ) is a switch with four electrical connectors. Two of which are respectively connected, upon actuation, the connections are reversed. It is used for cross-connects, which can be used for example in a large room with several doors the light on and off of each switch. Cross switch can be used if the consumer is to be switched by more than two places. In this case, at the beginning and at the end of a toggle switch and between any number of intermediate switch. This swap the corresponding wires when activated. If a consumer of more than 3 digits are switched off, is often dependent upon the management structure, a circuit from switches and latching relay economical. Here satisfy two conductors per button, the cross switch requires 4 wires.
