Intelligent three-way switch systems

An intelligent three-way slave switch, comprising:

• a slave switch first live terminal, a slave switch second live terminal, a slave switch traveler terminal, a slave switch neutral terminal, and a slave switch ground terminal;
• and
• a switch control unit, wherein the switch control unit comprises:
• a switch control unit first terminal and a switch control unit second terminal;
• wherein the switch control unit first terminal is connected to the slave switch traveler terminal to receive a low voltage DC power supply, wherein when the switch control unit receives one or more switch control instructions, the switch control unit generates a negative pulse at the switch control unit first terminal and the negative pulse is sent to an intelligent three-way master switch to turn “ON” or “OFF” an electrical power supply through the slave switch traveler terminal.

An intelligent three-way switch system, comprising:

• an intelligent three-way master switch, wherein the intelligent three-way master switch comprises:
• a master switch first live terminal, a master switch second live terminal, a master switch traveler terminal, a master switch neutral terminal, a master switch ground terminal, a direct current (DC) power supply, a live wire relay, a switch control unit, and a live input terminal selector;
• an intelligent three-way slave switch, wherein the intelligent three-way slave switch comprises:
• a slave switch first live terminal, a slave switch second live terminal, a slave switch traveler terminal, a slave switch neutral terminal, a slave switch ground terminal, and a switch control unit;
• and
• a load, wherein the load comprises a load live terminal, a load neutral terminal, and a load ground terminal, and the intelligent three-way switch system controls an electrical power supply to the load,
• wherein the intelligent three-way master switch, the intelligent three-way slave switch, and the load are connected in serial, and the DC power supply provides DC power to the live wire relay, the switch control unit of the intelligent three-way master switch, and the switch control unit of the intelligent three-way slave switch for an operation of the intelligent three-way switch system.
