Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An intelligent multi-way master switch, comprising:
a master switch first live terminal, a master switch second live terminal, a master switch traveler terminal, a master switch neutral terminal, and a master switch ground terminal;
a local switch control unit, wherein the local switch control unit receives one or more switch control instructions and controls a live wire relay; and
the live wire relay, wherein the live wire relay detects a negative pulse from the local switch control unit, and turns “ON” or “OFF” an electrical power between the master switch first live terminal and the master switch second live terminal;
a live input terminal selector, wherein the live input terminal selector comprises a first input terminal, a second input terminal, and an output terminal, wherein when an electrical power input is connected through a three-wire electrical cable, the first input terminal is connected to the output terminal, and when the electrical power input is connected through a four-wire electrical cable, the second input terminal is connected to the output terminal, and
a direct current (DC) power supply, wherein the DC power supply receives the electrical power through the live input terminal selector, and provides a low DC voltage to the live wire relay and the local switch control unit for an operation of the intelligent multi-way master switch.
