Using these Kailh Red Linear mechanical key switches is a breeze. First, if you're using them with our NeoKey boards like the Socket Breakout or the FeatherWing, just place the switches in the appropriate spots. If you opt for mechanical key sockets, you won't need to solder - simply insert the switches. To install the key caps, just snap them right onto the switches. As for maintenance, keep the switches clean by gently blowing away any dust or debris from time to time. Avoid getting them wet as moisture can damage the internal components. If you notice any issues with the smoothness of the keystrokes, it might be a sign that a switch needs to be replaced. And remember, we have different colors of these switches available if you want to change up the feel of your keyboard.
