- Battery
- Solar panel
The type of power source that is used will depend on the specific application. For example, if the 3-way switch wiring diagram is being used to control a light fixture in a home, then a circuit breaker or fuse box would be the most common choice. If the 3-way switch wiring diagram is being used to control a light fixture in a remote location, then a battery or solar panel would be a more suitable choice.
Light fixture
In a 3-way switch wiring diagram, the light fixture is the device that will be turned on and off by the switches. The light fixture is connected to the switches by wires, and when a switch is turned on, the electricity flows through the wires to the light fixture, turning it on. When the switch is turned off, the electricity stops flowing to the light fixture, turning it off.
- Type of Light Fixture: The type of light fixture that is used will depend on the specific application. For example, a ceiling light fixture would be used in a room, while a wall sconce would be used in a hallway.
- Location of Light Fixture: The location of the light fixture will also depend on the specific application. For example, a light fixture would be placed in the center of a room to provide general lighting.
- Power Requirements: The power requirements of the light fixture will depend on the type of light fixture that is used. For example, a fluorescent light fixture will require less power than an incandescent light fixture.
- Connection to Switches: The light fixture will be connected to the switches by wires. The wires will be connected to the terminals on the light fixture and the switches.
By understanding the connection between the light fixture and the switches, you can ensure that the 3-way switch wiring diagram is wired correctly and that the light fixture will operate properly.
3-way switches
In a 3-way switch wiring diagram power at light, the 3-way switches are the devices that allow you to control a light fixture from two different locations. This is achieved by using a traveler wire to connect the two switches. When one switch is turned on, the traveler wire carries the power to the other switch, which then completes the circuit and turns the light on. When the other switch is turned on, the traveler wire carries the power back to the first switch, which then completes the circuit and turns the light off.
- Components of a 3-way switch: A 3-way switch has three terminals: a common terminal, a traveler terminal, and a brass screw terminal.
