A pressing switch mechanism includes a housing, a board that is accommodated in the housing, a switch portion that is fixed to the board and generates a click feeling according to pressing a pressed portion in a direction approaching the board, and an operation plate which includes a bowl-shaped recessed surface that is recessed from a surface of the housing, of which an outer peripheral edge is supported by the housing, which is displaceably bent in the direction approaching the board, and in which a bottom wall portion of the recessed surface protruding inward the housing is in contact with the pressed portion.

A push switch according to the present disclosure includes: a case including a recess and having an upper surface located around the recess; a movable member disposed in the recess and including a pressure-receiving portion; a contact portion which switches between ON and OFF by deformation of the movable member; a first sheet including a joining portion which is opposite to the upper surface of the case, a pressing portion located above the pressure-receiving portion, and an intermediate portion located between the joining portion and the pressing portion, the first sheet covering the recess at the pressing portion and the intermediate portion; and a second sheet joined to the first sheet. The joining portion of the first sheet is joined to the upper surface of the case, and the second sheet is joined to the intermediate portion of the first sheet.

A push switch 1 includes a movable contact member 20 with a bulging portion 20a. The push switch 1 has a fixed contact member 10 with a first fixed contact portion 10a and a second fixed contact portion 10b. The push switch 1 includes an electrically conductive vibration damping member 25 elastically deformable by an operating force lower than load for inversion operation of the bulging portion 20a. When the movable contact member 20 is operated from the initial state, the vibration damping member 25 is deflected due to elastic deformation while the operating force during the elastic deformation of the vibration damping member 25 increases monotonically. When the movable contact member 20 returns from the bulging portion 20a being in an inverted state to the initial state, the vibration damping member 25 absorbs the vibrations from the movable contact member 20.

A switch unit includes a wiring board, a spacer, a movable contact element, a pressing element, and a protective sheet. A first stationary contact element and a second stationary contact element having rectangular shapes are provided on an upper surface of the wiring board. A contact section includes the movable contact element, the first stationary contact element, and the second stationary contact element. The movable contact element is mounted on a portion of the upper surface of the wiring board that is exposed from an inside of an opening of the spacer so that an outer edge of the movable contacts the second stationary contact element. The first stationary contact element continuously extends from a region of the wiring board facing a movable contact portion of the movable contact element to a region of the wiring board outside a region of the wiring board onto which the movable contact element is projected.

A push switch according to the present disclosure includes: a case including a recess and having an upper surface located around the recess; a movable member disposed in the recess and including a pressure-receiving portion; a contact portion which switches between ON and OFF by deformation of the movable member; a first sheet including a joining portion which is opposite to the upper surface of the case, a pressing portion located above the pressure-receiving portion, and an intermediate portion located between the joining portion and the pressing portion, the first sheet covering the recess at the pressing portion and the intermediate portion; and a second sheet joined to the first sheet. The joining portion of the first sheet is joined to the upper surface of the case, and the second sheet is joined to the intermediate portion of the first sheet.

A sealed electronic module (1) including at least one actionable part (2), the module (1) including a case (2) having: a watertight compartment (4) containing a printed circuit board (5), the compartment (4) being formed by a housing (13) with a unique opening (20), the housing (13) including the printed circuit board (5), and a sealing element (6a, 6b) configured for closing tightly the unique opening (20) by being fixed to the housing (13) and the printed circuit board (5).

An input device includes a fixed electrode, a movable electrode, and a movable member. The movable member is configured to elastically deform by receiving pressing force to relatively displace the movable electrode toward the fixed electrode. The movable member has an outer peripheral part. The outer peripheral part includes a suppression structure configured to suppress the movable member from being elastically deformed by the pressing force.

A pressing operation body includes an inversion spring having a dome shape; and a rubber stem configured to bend in response to pressing and press the inversion spring. The inversion spring includes a dome portion, and a plurality of leg portions that are extended outward from an outer peripheral edge of the dome portion. The rubber stem includes a base portion configured to support a lower edge of the rubber stem. The base portion includes a plurality of retaining portions configured to retain the plurality of leg portions of the inversion spring.
