How to Wire a Switch with a Pilot Light
Wiring a switch with a pilot light can be a daunting task, but with the right guidance, it can be a manageable DIY project. In this article, we will walk you through the step-by-step process of wiring a switch with a pilot light. Whether you’re a beginner or an experienced electrician, this guide will help you understand the basics and provide you with the confidence to tackle this project.
Understanding the Basics
Before we dive into the wiring process, it’s essential to understand the basics of a pilot light and how it works. A pilot light is a small flame or glow that is used to ignite a gas burner, such as a water heater or a furnace. The pilot light is typically wired to a switch, which is used to turn the pilot light on and off.
The Components You’ll Need
To wire a switch with a pilot light, you’ll need the following components:
- A switch (usually a SPST or SPDT switch)
- A pilot light
- A power source (e.g. 120V or 240V)
- Wires (e.g. 14-gauge or 16-gauge)
- Electrical connectors (e.g. wire nuts or connectors)
Wiring the Pilot Light
To wire the pilot light, follow these steps:
- Turn off the power: Before you start wiring, make sure to turn off the power to the pilot light at the main electrical panel.
- Identify the pilot light terminals: Locate the terminals on the pilot light and identify the positive (+) and negative (-) terminals.
- Connect the positive wire: Connect the positive wire (usually black or red) to the positive terminal on the pilot light.
- Connect the negative wire: Connect the negative wire (usually white or copper) to the negative terminal on the pilot light.
- Secure the wires: Use wire connectors or wire nuts to secure the wires to the terminals.
Wiring the Switch
To wire the switch, follow these steps:
- Identify the switch terminals: Locate the terminals on the switch and identify the normally open (NO) and normally closed (NC) terminals.
- Connect the pilot light wire: Connect the positive wire from the pilot light to the NO terminal on the switch.
- Connect the switch wire: Connect the negative wire from the pilot light to the NC terminal on the switch.
- Connect the power wire: Connect the positive wire from the power source to the common terminal on the switch.
- Connect the neutral wire: Connect the negative wire from the power source to the neutral terminal on the switch.

If you encounter any issues while wiring the switch with a pilot light, here are some troubleshooting tips to help you resolve the problem:
- Check the power: Make sure that the power is turned off at the main electrical panel before starting the wiring process.
- Check the connections: Verify that the connections are secure and not loose.
- Check the wires: Make sure that the wires are properly sized and not damaged.
- Check the pilot light: Verify that the pilot light is functioning properly and not blocked.
Conclusion
Wiring a switch with a pilot light is a relatively simple process, but it requires attention to detail and a basic understanding of electrical wiring. By following the steps outlined in this article, you should be able to successfully wire a switch with a pilot light and enjoy the benefits of having a reliable and efficient gas burner. Remember to always turn off the power at the main electrical panel before starting the wiring process and to follow proper safety protocols when working with electrical wiring.
