Optical switches are a type of switch commonly used in keyboards and other input devices. Unlike traditional mechanical switches, which use physical contacts to register key presses, optical switches rely on light signals to detect keystrokes.

In an optical switch, a beam of infrared light is emitted across the switch cavity. When a key is pressed, the interruption of this light beam by the actuation of the switch is detected by a sensor, registering the keystroke. This mechanism offers several advantages over mechanical switches:

1. Durability: Optical switches have no physical contacts that can wear out over time, resulting in a longer lifespan compared to mechanical switches. This makes them particularly well-suited for heavy or prolonged use, such as in gaming or professional environments.

2. Faster response times: Optical switches typically have shorter debounce times, leading to quicker registration of key presses. This can be advantageous in fast-paced gaming scenarios or situations where rapid typing is required.

3. Enhanced reliability: The absence of metal contacts in optical switches reduces the risk of oxidation or corrosion, which can degrade performance over time in mechanical switches. Additionally, optical switches are less prone to issues such as double-clicking or key chatter.

4. Customization options: Optical switches often offer customizable actuation points, allowing users to adjust the sensitivity of their keyboards to suit their preferences or specific gaming or typing needs.

Overall, optical switches provide a more reliable, durable, and responsive typing experience compared to mechanical switches, making them a popular choice among gamers, typists, and professionals seeking high-performance input devices.

Optical switch:PCB use the optical principle to trigger the buttons. When the keyboard is powered on, each optical switch always light on. When one of the optical switch is pressed, the button will be triggered when the light source is blocked [even if the button has not been pressed to the end]. The advantage is that this trigger is relatively faster, but it also consumes more power.
