Abstract
A keyswitch including a lever mounting plate with which the bottom ends of a pair of levers can engage, and an actuator with which the top ends of the pair of levers can engage. The lever mounting plate is mounted to a holding plate, and is placed on a membrane switch. The actuator is mounted to the keytop. The lever mounting plate and the actuator each include a rotation engaging section and a slide engaging section. The rotation engaging section has an open portion and allows a rotating pin of one of lever members to rotatably engage therewith. The slide engaging section has an open portion, and allows a slide pin of the other lever member to engage therewith. The open portion of the rotation engaging section and that of the slide engaging section open in the same direction so that the pair of lever members can be mounted to the lever mounting plate and to the actuator by only moving the pair of lever members from one side to the other.
