— a hybrid design that combines elements of mechanical and membrane keyboards (see above for more details on both). In this case, these features are combined in each individual key. Typically, under each button in such keyboards, there is a membrane, but inside this membrane, there is not just a pair of contacts, but a mechanical spring system. Thus, this design combines the advantages of both options. At the same time, mechanical-membrane systems are quite expensive. Therefore, their main area of application is high-end gaming keyboards, and even among such devices, this option is quite rare.
