Making a Secret Book Light Switch


  • 1 pc – hardback book
  • 1 pc – 1/16 x 3/4″ (1.6 x 19 mm) aluminum bar
  • 1 pc – SPDT (Single pole double throw) on-on push button switch
  • 4 pcs – #6 x 1/4″ (6.4 mm) self-tapping sheet metal screws
  • 1 pc – 3/4″ (19 mm) wide brass hinge
  • 1 pc – Lutron Credenza lamp dimmer. This is can be replaced with an extension cord.
  • 2 pcs – short pieces of shrink tubing
  • A roll of rubber tape
  • A small zip tie


  • Measuring tape
  • Ruler
  • Sharpie/Marker
  • Vise/vise grips
  • Drill with drill bits
  • Screwdriver
  • Pliers
  • Soldering iron/gun


Step 1: Prepare the Book

  1. Choose a Hardback Book: Select a book that blends well with others on your shelf, ensuring it is not too thin.
  2. Hollow Out the Book: Carefully cut a compartment within the pages of the Book to house the switch mechanism. Leave a few pages uncut at the beginning and end to maintain its book-like appearance.

Step 2: Install the Switch and Hinge

  1. Mount the SPDT Switch: Position the SPDT (Single Pole Double Throw) switch inside the hollowed-out Book. Use the sharpie to mark the screw locations, then pre-drill holes for the self-tapping screws.
  2. Attach the Brass Hinge: Secure the hinge to the back cover of the Book with screws, allowing it to open and close like a door. Ensure the hinge is mounted discreetly for a seamless look.

Step 3: Prepare the Aluminum Bar

  1. Cut the Aluminum Bar: Measure and cut the aluminum bar to a length that fits comfortably inside the spine of the Book. This Bar will act as the lever for the switch.
  2. Attach the Bar to the Switch: Drill a small hole at one end of the aluminum bar. Connect it to the SPDT switch using a small zip tie, ensuring it can pivot to activate the switch.

Step 4: Wire the Electrical Components

  1. Prepare the Lutron Credenza Lamp Dimmer: If using an extension cord instead, cut it to length and strip the ends of the wires.
  2. Connect the Dimmer to the Switch: Solder the wires from the lamp dimmer or extension cord to the SPDT switch. Cover the connections with shrink tubing to ensure safety.
  3. Insulate with Rubber Tape: Wrap all exposed wires and connections with rubber tape to prevent short circuits.

Step 5: Final Assembly

  1. Secure the Components Inside the Book: Use the remaining self-tapping screws to fix the electrical components and aluminum bar in place within the Book.
  2. Test the Mechanism: Ensure the aluminum bar activates the switch when the Book is tilted. Adjust the positioning if necessary.

Step 6: Installation

  1. Place the Book on the Shelf: Position your secret Book light switch on a bookshelf among other books. Make sure it blends in and is easily accessible.
  2. Connect to a Light Source: Plug the lamp dimmer (or extension cord) into a power outlet and connect it to a lamp or other light source.

Step 7: Enjoy Your Secret Book Light Switch

  • Operate Your Light: Tilt the modified Book to turn the connected light on or off. Enjoy the element of surprise and the functional novelty you’ve created.

In this section, we’ll explore how innovative technologies can be seamlessly combined with projects like the secret book light switch, elevating the traditional concept of hidden compartments to a new level of sophistication.

Smart Home Automation

Imagine the secret book light switch not just as a manual mechanism but as a smart device within your home automation system. By integrating it with smart home platforms, you can control the light with voice commands or through a mobile app. This not only adds a layer of convenience but also surprises guests with the blend of traditional aesthetics and modern technology.

Security Features

The secret book light switch can serve as a discreet method to activate security systems or safes. By incorporating biometric scanners or password-protected mechanisms within the book, you add a layer of security that is both innovative and hidden in plain sight. This approach ensures that valuable items or sensitive information are kept safe, with access granted only to those who know the secret.

Energy Efficiency

Link the secret book light switch to energy-efficient lighting solutions, such as LED lights that can be dimmed or color-changed through smart home technology. This not only allows for energy savings but also lets you create ambiance and mood lighting in any room, all controlled by the seemingly innocuous act of tilting a book.

Connectivity and Control

With the integration of Wi-Fi or Bluetooth capabilities, the secret book light switch can be controlled remotely. This feature is particularly useful for lighting control when you’re not at home, providing both the illusion of presence for security and the convenience of returning to a well-lit house.

Educational Tool

For families with children, integrating technology with projects like the secret book light switch can be an educational tool. It provides a hands-on experience with basic electronics, programming, and the principles of automation, encouraging curiosity and innovation in young minds.

Personalization and Convenience

Technology allows for personalization of the secret book light switch, from custom activation sequences to programmable settings that adjust lighting based on the time of day or activity. This level of customization enhances the user experience, making everyday interactions with your home more engaging and tailored to your lifestyle.

By integrating technology with secret compartments like the secret book light switch, you not only enhance the functionality and security of these features but also introduce a level of sophistication and customization that reflects the modern, connected home. This fusion of the traditional and technological opens up new possibilities for creative home design, making everyday objects extraordinary.

Safety and Legal Considerations

When creating a secret book light switch, it’s paramount to prioritize safety and adhere to legal standards. This ensures not only the well-being of everyone involved but also the legality and integrity of your creative endeavor. Below, we delve into key considerations to keep in mind, ensuring your project is both safe and compliant.

Understand Electrical Safety

  • Respect Electrical Codes: Before starting, familiarize yourself with local electrical codes and regulations. These codes are designed to ensure safety and prevent hazards. When integrating a secret book light switch, it’s crucial to understand how to handle electrical wiring and components safely.
  • Use Correct Materials: Ensure all electrical materials used, such as the Lutron Credenza lamp dimmer or an alternative extension cord, are rated for the type of use you have in mind. Using materials not suited for electrical projects can pose significant risks.
  • Insulation and Protection: Utilize the provided shrink tubing and rubber tape to insulate all exposed wires thoroughly. Proper insulation prevents short circuits, which can lead to fires or electric shocks.

Compliance with Building Regulations

  • Permit Requirements: Some jurisdictions may require a permit for electrical modifications, even for seemingly minor projects like a secret book light switch. Check with your local building authority to confirm if your project requires a permit.
  • Professional Inspection: Consider having your completed secret book light switch inspected by a certified electrician. This step is crucial to ensure that the installation is safe and up to code, providing peace of mind and avoiding potential legal issues down the line.

Avoid Structural Damage

  • Careful Installation: When installing your secret book light switch, be mindful of the structural integrity of the area. Avoid drilling or cutting into load-bearing walls or areas where you might damage existing electrical wiring.
  • Secure Mounting: Ensure the secret book and its components are securely mounted. The aluminum bar and brass hinge should be attached in a manner that supports the weight of the book without risk of falling, which could lead to injuries or damage.

Privacy and Ethical Considerations

  • Respect Privacy: While the allure of a secret book light switch includes the element of surprise and hidden functionality, ensure that its installation and use do not infringe on the privacy of others, especially in shared spaces.
  • Disclosure to Buyers: If you plan to sell your home, disclose the presence of the secret book light switch to potential buyers. Hidden electrical modifications can affect the home inspection process and the overall transaction.

Making a secret book light switch is a rewarding project that blends creativity with functionality. However, the excitement of this DIY endeavor should always be balanced with a commitment to safety and adherence to legal requirements. By following these guidelines, you can enjoy the charm and utility of your secret switch without compromising on safety or legality.


Crafting a secret book light switch offers an innovative way to merge functionality with a touch of mystery in your home decor. It requires careful attention to detail, safety, and legal considerations to ensure the project enhances your living space without compromising security. Embracing this creative endeavor not only personalizes your environment but also introduces a unique element that captivates and delights.
