Tactile switches provide, as the name suggests, additional tactile feedback as the key actuates. As you press the key down, there is a noticeable bump which lets you know that your key press has been registered.
The Cherry MX Clear is one of the less common switches, designed to be in spacebars of Brown style keyboards. If you had/have a Green keyboard, and love the feel, but can't stand the noise it makes, these switches are the next best thing. They provide the feedback, without the click.
These switches are plate mounted, and have mounting holes for an LED, so you can fix, or make your own RGB backlighted keyboard!
