This wiring diagram for a three-way switch is designed to control lighting from three or more locations. For the connection, you need to use two-way switches (switches) and crossover switches (switches). The video shows in detail how to connect a three-way switch, how to connect a crossover switch, and how to use these switches to create a very useful circuit for controlling lighting from multiple locations.
Before watching, we recommend watching the video "How to Connect a Single-Push Switch" -    • Как подключить двухклавишный проходной вык...
