An optical in connection, also known as TOSLINK or SPDIF, is used to input an optical digital audio signal into a device, such as a soundbar or receiver. This allows the device to receive and process the audio signal from an external source, such as a Blu-ray player or gaming console. On the other hand, an optical out connection is used to output an optical digital audio signal from a device to another external device, such as a soundbar or amplifier. This allows the device to send the audio signal to another device for playback or further processing. In summary, an optical in connection receives an audio signal, while an optical out connection sends an audio signal. **

Optical switches are a type of mechanical keyboard switch that uses light to register key presses. When the key is pressed, an infrared light beam is interrupted, which triggers the switch to register the key press. This type of switch offers faster response times and longer durability compared to traditional mechanical switches. Linear switches are a type of mechanical keyboard switch that provides a smooth and consistent keystroke without any tactile bump or audible click. When the key is pressed, the switch moves straight up and down without any resistance or feedback, making it ideal for fast and precise typing or gaming. These switches are popular among users who prefer a quieter and more linear typing experience. **
