摘要： [Problem] To provide a pushbutton switch member capable of achieving a favorable operation feeling, a long stroke, and a strong click feeling that should be provided by a dome-shaped movable contact.
[Solution] The present invention pertains to a pushbutton switch member including: a dome-shaped movable contact; and an operation key disposed on a protrusion side of the movable contact and contacting with the 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 includes: a key body; a dome part connected with an outer periphery of the key body and deformable by pushing of the key body toward the substrate; a foot part connected with an outer periphery of the dome part and fixed on the substrate; and a protrusion provided on a top surface of the key body or the outer periphery of the key body, protruding from the top surface of the key body, and deformable by compression during operation of pushing the operation key toward the substrate. The movable contact includes: an upper contact part disposed in contact with a site directly below the key body and configured to contact with a contact of the at least two contacts when the key body is pushed in; and an outer fixing part disposed at the upper contact part or outside of the upper contact part in a radial direction and fixed outside of the key body of the operation key in the radial direction.

摘要： [Problem] To provide a pushbutton switch member which is compact and able to handle a high load, and which easily delivers a feeling of full stroke and strong click.
[Solution] The present invention pertains to a pushbutton switch member 30 provided with a dome-shaped movable contact 20 and an operation key 10, positioned facing and separate from the protrusion side of the movable contact 20. Pushing the operation key 10 in the direction of the movable contact 20 causes the movable contact 20 to electrically connect at least two contacts 41, 42 on a substrate 40. The operation key 10 is provided with: a key body 11; a dome part 12 connected with an outer periphery of the key body 11, and deformable by pushing of the key body 11 toward the substrate 40; and a foot part 14 connected with an outer periphery of the dome part 12, and fixed on the substrate 40. The movable contact 20 is provided with: an upper contact part 21 spaced apart from a site directly below the key body 11, and which makes contact with a contact 42 when the key body 11 is pushed in; and an outer fixing part 25 disposed at the upper contact part 21, or further outside thereof in the radial direction, and fixed outside of the key body 11 in the radial direction.
