Utilizing electro-capacitive key switches, the Plum84 combines the silent operation of a rubber dome keyboard with the reliability and tactility of a mechanical keyboard. Plus, these unique switches are compatible with Cherry MX-style keycaps. The construction consists of a rubber dome that houses a slider, over which is a coiled spring and a printed circuit board. The result: limited resistance from a soft tactile bump, and individually weighted keys for a consistent feel.
