How to Wire a Double 2 Way Light Switch: A Comprehensive Guide
Imagine this: you’re in the middle of cooking dinner, and you realize you need to adjust the lighting in the kitchen. But the light switch is on the other side of the room, and you don’t want to interrupt your cooking flow. What do you do? If you had a double 2 way light switch, you could control the lights from both sides of the room, saving you time and hassle.
Wiring a double 2 way light switch may seem like a daunting task, but it’s actually quite straightforward with the right instructions. In this article, we’ll provide you with a step-by-step guide on how to wire a double 2 way light switch, along with helpful tips and expert advice to ensure a successful installation.
Understanding Double 2 Way Light Switches
Before we dive into the wiring process, let’s first clarify what a double 2 way light switch is. A double 2 way light switch is a type of electrical switch that allows you to control a single light fixture from two different locations. It consists of two toggle switches that work together to control the flow of electricity to the light fixture.
Double 2 way light switches are commonly used in hallways, staircases, and other areas where you need to control lighting from multiple locations. By installing a double 2 way light switch, you can eliminate the inconvenience of having to walk back and forth to adjust the lights.
Wiring a Double 2 Way Light Switch
Materials you’ll need:
- Double 2 way light switch
- Electrical wire (14 or 12 gauge)
- Wire strippers
- Screwdriver
- Electrical tape
- Voltage tester
Step 1: Identify the existing wiring
Turn off the power to the circuit you’ll be working on at the breaker panel. Remove the faceplate from the existing single-pole light switch and identify the wires connected to it. There should be three wires: a black wire (hot), a white wire (neutral), and a ground wire (usually bare copper or green).
Step 2: Remove the existing switch
Using a screwdriver, loosen the screws holding the existing switch in place and pull it out of the electrical box. Make sure to label the wires so you can identify them later.
Step 3: Connect the wires to the new switch
Match the wires from the electrical box to the corresponding terminals on the double 2 way light switch. The black wires connect to the “COM” terminals, the white wires connect to the “LINE” terminals, and the ground wire connects to the “GND” terminal.
Step 4: Install the new switch
Push the new switch into the electrical box and tighten the screws to secure it in place. Make sure the wires are securely connected and not loose.
Step 5: Test the switch
Turn on the power at the breaker panel and flip the toggle switches on the double 2 way light switch. The light should turn on when you flip either switch and turn off when you flip both switches.
Tips and Expert Advice
- Test the voltage before you start working. Use a voltage tester to ensure that the power is off at the electrical box before you begin wiring.
- Use the correct wire size. For most residential lighting circuits, 14 or 12 gauge wire is sufficient.
- Strip the wires properly. Use wire strippers to remove about 1/2 inch of insulation from the ends of the wires.
- Connect the wires securely. Make sure the wires are fully inserted into the terminals and tightened securely.
- Use electrical tape to insulate the connections. Wrap electrical tape around all the exposed wires to prevent short circuits.
- Install the faceplate. Once the switch is wired and tested, install the faceplate to cover the electrical box.
Frequently Asked Questions
Q: Can I wire a double 2 way light switch using only three wires?
A: No, you need at least four wires to wire a double 2 way light switch: two for the power supply and two for the traveler wires.
Q: What is the difference between a 2 way and a 3 way light switch?
A: A 2 way light switch allows you to control a light fixture from two locations, while a 3 way light switch allows you to control a light fixture from three locations.
Q: Can I replace a single-pole light switch with a double 2 way light switch?
A: Yes, but you may need to add an additional wire to the electrical box.
Q: How do I find the traveler wires?
A: Traveler wires are typically the same color in pairs. In most cases, they are black or red.
Conclusion
Wiring a double 2 way light switch is a relatively simple task that can greatly improve the convenience and functionality of your
