  • Patent number: 11515104
    Abstract: 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.

  • Patent number: 11289282
    Abstract: A switch used in an operation device such as a mouse has flexibility, and includes a movable member in which a first end side is fixed as a swing fulcrum and a second end side swings, and a pressing member that presses a portion between the first end and the second end of the movable member by receiving a pressing force from an outside source. Bent portions that are bent in a swinging direction are formed in side portions of the movable member. When the movable member warps by being pressed by the pressing member, the bent portions resist against the warping of the movable member, and therefore an operator can have click feeling.

  • Patent number: 10559435
    Abstract: A highly durable, quiet switch includes a housing, a stationary contact terminal including a fixed portion, a moving contact terminal, a moving contact unit including a body, a moving portion, and an urging member and connected to the moving contact terminal, an operating unit, a first elastic unit that comes in contact with the moving contact unit and elastically deforms when the moving portion moves away from the fixed portion, and a second elastic unit including a contact point between the moving portion and the fixed portion facing the moving portion to come in contact with the moving portion. The second elastic unit elastically deforms and electrically connects the stationary and moving contact terminals when the moving portion moves toward the fixed portion and comes in contact with the contact point.
