ABSTRACT:
A multi-directional input key is capable of plural inputs through multi-directional operation, wherein the plural inputs are realized by a novel multi-directional operation, instead of the conventional operation in which force is applied to the operation surface so as to push it in deeply. There is provided a central key top equipped with an upper key top protruding from an insertion hole of an outer-ring key top and a lower key top having a pushing member protruding downwardly therefrom. This central key top is supported on a key sheet so as to be slidable in the direction of the hole inner surface of the insertion hole. And, when the central key top is caused to slide, an upper contact and a lower contact of a membrane switch are brought into contact with each other to effect input under the pressure from the pushing member.
