- A mechanical keyboard uses an actual physical switch underneath each key to determine when a key has been pressed. Press the key, and you press the switch down. Press the switch down, and the keyboard sends a signal to the PC telling it that you've pressed that key.
- That system is quite different from the one employed by most keyboards you're likely to encounter. The vast majority of keyboards used with PCs these days consist of three layers of plastic membranes lying underneath the set of keys. When the top and bottom layers connect, they close an electrical circuit that causes the keyboard to send information to the PC. The middle membrane keeps the two layers separate, but it has holes where the various keys are positioned. When you press a key all the way down, you push a dome-shaped piece of rubber or silicone through the holes in the middle membrane to connect the top and bottom membranes, creating the circuit that causes the keyboard to send the corresponding input. Technically, the keyboard operates very similarly to the keypad on your microwave oven or the remote control for your TV. Those device don't use rubber domes, however, which is why they don't provide much tactile feedback. Most console gaming system gamepads use a rubber-dome system, as well.
