LED Tact Switch

The 7*7mm Red-green Led Tact Switch has several features that make it popular among electronic designers. The switch typically comes in a compact form factor, making it suitable for applications where space is limited. Common dimensions include 6x6mm or 7x7mm, allowing for easy integration into electronic devices.

A Through Hole Led Tact Switch operates on the same fundamental principle as other tact switches. When the switch is pressed, it actuates a mechanical mechanism that closes or opens an electrical circuit, providing users with a distinct tactile “click” to confirm their input. What sets this switch apart is its integrated red and blue LEDs, which can be independently controlled or programmed to display various lighting patterns.

Typically, these PCB Led Tact Switches are designed to be compact, with a small footprint that allows for easy integration into printed circuit boards (PCBs). They can be surface-mounted (SMD) or through-hole mounted, depending on the specific requirements of the application. The red and blue LEDs are usually powered by a low-voltage source, often within the range of 3V to 5V, and can be controlled using microcontrollers or other electronic circuits.

The Power of Dual-Color Illumination

Clear Status Indication

One of the primary advantages of the red-blue illumination is its ability to provide clear and distinct status indication. Red is commonly associated with caution, error, or stop signals, while blue often represents normal operation, activation, or a positive status. For example, in a power supply unit, a blue LED might illuminate when the unit is functioning properly, while a red LED would light up in the event of an overvoltage, overcurrent, or short-circuit condition. This visual cue allows users to quickly assess the status of the device without having to rely on complex diagnostic tools or readouts.

Interactive User Experience

In addition to status indication, the red-blue illumination can enhance the user experience by adding an element of interactivity. In gaming devices, for instance, different lighting patterns can be used to represent various in-game actions or power-ups. A rapid flashing of blue and red LEDs could indicate a special attack or a critical health warning. In consumer electronics like smartphones or tablets, the illuminated switch can be used as a notification light, with red indicating an urgent message or missed call, and blue signifying a new email or social media notification.

Customization and Branding

The ability to control the red and blue LEDs independently also offers opportunities for customization and branding. Manufacturers can program the switch to display unique lighting sequences or color combinations that align with their brand identity. This not only makes the product more visually appealing but also helps to create a memorable user experience, differentiating the product from competitors in the market.

They include:

1. Contact form: This switch comes in a single-pole, single-throw (SPST) configuration, which means that it has two terminals that are connected when the switch is activated and open when it is not.

2. Illumination: The switch has an LED that illuminates when the switch is activated, making it easy to locate in low lit environments. The LED comes in red-green colors, which adds to the switch’s aesthetics.

3. Operating force: The switch has a low operating force, making it easy to trigger, and reducing the chances of operator fatigue.

4. Mounting: The switch is designed to easily fit into a standard 7*7mm through hole printed circuit board (PCB).

5. Durability: The switch has a long lifespan, and it can handle up to 100,000 cycles of operation.
