What is a tact switch used in string lights?

Whenever the holiday season arrives, people adorn colorful string lights, enhancing the atmosphere. Among these, the application of tact switches in string lights has become a noteworthy innovation. Traditional string light decorations were once simply about turning on and off. However, tact switches have injected more imagination and creativity into string lights.


What is a tact switch?

tact switch structure

A tact switch, also known as a tactile push button switch, is a switch belonging to the category of electronic components. Also known as a push button switch or sensitive switch, it operates by applying the necessary pressure in the direction of the switch to complete the circuit. When the external force is removed, the switch is disconnected. Its internal structure relies on the force change in a metal snap dome to achieve on-off functionality. A tact switch is mainly composed of pins, contacts, bases, snap domes, dust covers, covers, and buttons. Waterproof types are equipped with a special waterproof film on the snap dome.

Characteristics of tact switches

As a common type of switch, tact switches (Tact Switches) have numerous advantages in various applications, including:

  1. Ease of operation: The operation of tactswitches is usually simple and intuitive. Users only need to press or release the button to establish or break the circuit, making it user-friendly without requiring complex technical knowledge.
  2. High reliability: Most tactswitches adopt a mechanical structure, offering robustness and stability. They endure long-term usage without easily malfunctioning, representing a reliable switch type.
  3. Variety of types to choose from: Tactswitches come in various types and specifications, including surface mounttype, snap-in type, top-push type, side-push type, waterproof, and illuminated versions, catering to diverse circuit connection needs.
  4. Flexible design: Tactswitches can be designed in various shapes, sizes, and styles to match different decoration requirements and environments. Their design aesthetics can complement household or commercial settings.
  5. Wide application: Tactswitches are widely used in various electronic devices, lighting systems, circuit controls, instrumentation, smart homes, automotive electronics, and more, providing a simple and effective control method for these devices.

Therefore, tact switches offer several advantages such as ease of use, reliability, flexible design, and broad applications, making them widely used in various electrical control fields.

The application of tact switches in string lights has brought more convenience and creativity to holiday decorations. Here is KANGERLE tact switch KEL-C015 applied in string lights:

  1. Mode switching function: Tactswitches can be designed to incorporate multiple lighting modes such as steady, flashing, and fading. By lightly pressing the switch button, users can easily switch between different lighting effects, adding variety and interest to holiday decorations.
  2. Brightness adjustment: Some string light setups integrate adjustable brightness functions. Through the integrated tactswitch, users can adjust the brightness of the string lights to suit their preferences.
  3. Color changes: For colored string lights, tactswitches can control the change of light colors. Pressing the switch or following specific operation modes can alter the light colors, creating different visual effects and enhancing the holiday atmosphere.
  4. Timing function: Some string lights come with timing functions. Utilizing the tactswitch and circuit board, users can set the operating time of the string lights. This feature helps conserve energy and allows for convenient time-saving settings.
  5. Smart control: Certain string lights are equipped with smart tactswitches that can connect to smart home systems. Through mobile apps or voice control, users can remotely manage the lighting, achieving a more intelligent light control system.

Tact switches bring added convenience and creativity to string lights. They enable users to easily control brightness, modes, colors, and operating times, creating diverse decorative effects for different scenarios and needs. Through these functions, tact switches offer string lights greater flexibility and customization possibilities, adding more fun and appeal to holiday decorations.
