The terminals are related in such a manner that when one swap is within the “on” place, the opposite swap is within the “off” place, and vice versa.
How Three-Means Switches Work
Three-way switches work through the use of a typical wire, a traveler wire, and two energy wires. The frequent wire is related to the facility supply. The traveler wire is related between the 2 switches. The facility wires are related to the sunshine fixture. When one swap is within the “on” place, electrical energy flows from the facility supply via the frequent wire, via the traveler wire, via the swap, and to the sunshine fixture. When the opposite swap is within the “on” place, electrical energy flows from the facility supply via the frequent wire, via the traveler wire, via the opposite swap, and to the sunshine fixture.
