Understanding 3-Way Switches
A 3-way switch is a type of electrical switch that allows you to control a light fixture or other electrical device from two or more locations. This switch is commonly used in hallways, stairways, and large rooms where it’s convenient to have multiple control points. A 3-way switch has three terminals: one common terminal and two traveler terminals. The common terminal is connected to the power source, while the traveler terminals are connected to the other 3-way switch or the load (light fixture).
How 3-Way Switches Work
When a 3-way switch is installed, it creates a circuit that allows the electricity to flow through the traveler terminals to the load. When one switch is flipped, it connects the traveler terminals, allowing the electricity to flow to the load. When the other switch is flipped, it breaks the connection, turning off the load. This setup allows you to control the load from multiple locations.
Understanding Regular Switches
A regular switch, also known as a single-pole switch, is a simple on/off switch that controls a light fixture or other electrical device from one location. This switch has two terminals: one connected to the power source and the other connected to the load. When the switch is flipped, it connects or breaks the circuit, turning the load on or off.
Key Differences Between 3-Way and Regular Switches
The main differences between 3-way switches and regular switches are:
- Number of terminals: 3-way switches have three terminals, while regular switches have two.
