Abstract: A first connector body includes a recess having a substantially rectangular shape in a planar view filled with a plurality of first connection units arranged in close contact in the longitudinal direction of the first connector body, wherein each first connection unit includes a first terminal and a first shield having a rectangular cylindrical shape with a substantially rectangular cross-section surrounding the periphery of the first terminal and extending in the mating direction.

Abstract: A pushbutton switch member has a dome-shaped movable contact and an operation key facing and separated from a movable contact. Pushing the operation key toward the movable contact causes the movable contact to electrically connect at least two contacts on a substrate. The operation key is provided with: a key; a dome connected with an outer periphery of the key, and deformable by pushing of the key toward the substrate; and a foot connected with an outer periphery of the dome, and fixed on the substrate. The movable contact is provided with: an upper contact spaced apart from a site directly below the key, and which makes contact with a contact when the key is pushed in; and an outer fixing part disposed at the upper contact, or further outside thereof in the radial direction, and fixed outside of the key in the radial direction.

Abstract: A pushbutton switch includes: a dome-shaped movable contact; and an operation key on a side of the movable contact. Pushing the operation key causes the movable contact to electrically connect at least two contacts. The operation key includes: a key body; a dome connected with an exterior of the key body and deformable by pushing the key body; a foot connected with an exterior of the dome; and a protrusion on top of the key body, protruding from the top, and deformable by compression. The movable contact includes: an upper contact in contact with a site below the key body and contacting the at least two contacts when the key body is pushed; and an outer fixing part at the upper contact in a radial direction and fixed outside of the key body of the operation key in the radial direction.
