Abstract

A key switch includes a base unit and a key-top unit. A number of contact terminal units are disposed on the base unit. The key-top unit moves vertically. The key-top unit includes an upper magnet attached to a bottom of the key-top unit. The base unit includes a lower membrane film on which a lower contact point is disposed; an upper membrane film on which an upper contact point that can be placed in contact with the lower contact point is disposed, and which is disposed above the lower membrane film; a spacer film which is interposed between the lower membrane film and the upper membrane film and includes a hole through which the upper contact point and the lower contact point can be placed in contact with each other; and a lower magnet which is fixed onto the upper membrane film and faces the upper magnet.
