Think of how the legs of a folding ironing table, table, or chair work: the scissor-like legs allow the table surface to move up and down, while remaining parallel to the floor. The scissors allow vertical movement without toppling.
In a regular keyboard, the vertical motion is regulated by a column of plastic that holds the keycap. In a very flat, laptop keyboard, it’s not possible to have a column that’s tall enough to hold the key vertical. So, instead, the plastic scissors keep the keycap level.
The Unicomp Ultra Classic is a clone of the classic IBM Model M, the “clicky” keyboard. It’s like the polar opposite of the scissor switch, but included here because sensitive typists also favor this type of keyboard.
