A key switch includes an actuator for rotatably engaging the upper end of one of lever members, which constitute a cross-linked member, therewith and slidably engaging the upper end of the other lever member therewith. After the cross-linked member engaged with the actuator at its upper end is mounted on a membrane switch, the bottom of a key top is retained on the actuator by a simple means a as press fitting. This simplifies a molding die for the key top and facilitates an operation of attaching the key top.
