A key structure includes a base, a movable mechanism movably positioned on the base, a sound generating member positioned on the base, and an adjusting unit movable relative to the base to be at a first position or a second position. The sound generating member has a hitting portion, which extends corresponding to an impact surface. When the adjusting unit is at the first position, and a pressing force is applied to the movable mechanism, the movable mechanism moves relative to the base and drives the sound generating member to move, so the hitting portion moves to hit the impact surface to generate a hitting sound. When the adjusting unit is at the second position, the adjusting unit restricts movement of the hitting portion, so the hitting portion cannot move to hit the impact surface.

A key structure includes a keycap, a base plate and a supporting element. The supporting element includes a first frame and a second frame. The supporting element is connected with the keycap and the base plate. Consequently, the keycap is movable upwardly or downwardly relative to the base plate. When the first frame and a second frame are combined together, a first span and a second span are formed sequentially. The second span is smaller than the first frame.

A microswitch includes a contact chamber that accommodates a contact mechanism that opens and closes an electrical circuit; an enclosure that accommodates the contact chamber; and a pressing component that accepts a pressure external to the enclosure. The pressing component may include an insertion part that is inserted into an insertion hole in the contact chamber and acts on the contact mechanism, the insertion part receiving a pressure external thereto and moving from a first side that is outward of the enclosure to a second side that is inward of the enclosure. The pressing component may include a shielding part that shields the insertion hole from the contact chamber side, the shielding part being larger than the insertion hole in a direction orthogonal to an insertion direction to block the insertion hole.

A push switch includes a housing including a bottom wall and a side wall, the housing extending in a first axis direction and a second axis direction in a plan view, and a fixed contact member configured to come into contact with a movable contact member, the fixed contact member being embedded in the bottom wall of the housing by insert molding, wherein the fixed contact member includes: a first terminal exposed to an outside from a first end portion in the first axis direction of the housing; and first extension portions, constituting a pair, that are both ends of the first terminal in the second axis direction, the first extension portions being bent upward and being embedded in the bottom wall or the side wall of the housing, or in both the bottom wall and the side wall of the housing, by the insert molding.

A switch assembly including a socket, a top cap, and an intermediate cart located in the socket. The intermediate cart is slidable with the socket. The top cap is in a spherical or pivot engagement with the intermediate cart. An activation force of the sliding movement is lower than an activation force of the spherical or pivot movement.
