  • Switch and operation device having a flexible swinging member
    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.

    Assignee: OMRON Corporation
