Deyi foam and foil is a provisional name for a Cherry MX mount, clicky foam and foil switch assumed to have been manufactured by Deyi Technology, based on the only keyboard known to use the switch. Unlike many other foam and foil switches, these do not appear to have discrete slider housings, with the slider guide shafts being moulded as a single plastic plate. Alps-style click leaves fit inside the guide shafts.
The switches have external return springs under the keycaps.
