Movable contact body for switch, and switch

A movable contact body for a switch, the movable contact body comprising:

• at least one movable contact having an upwardly convex leaf-spring shape;
• a cover member disposed so as to cover an upper surface of the movable contact;
• a frame-shaped adhesive sheet having a base layer and adhesive layers on both sides of the base layer, and arranged around an outside of the movable contact;
• and
• a holding member adhered to one of the adhesive layers, and disposed so as to face a lower surface of the movable contact, the holding member having a contact through-hole through which a top portion of the movable contact passes, wherein
• the frame-shaped adhesive sheet is a separate structure from that of the holding member, and
• the holding member has an electrically conductive surface, and supports a base of the movable contact on the electrically conductive surface.

A switch comprising:

• a substrate;
• a first fixed contact formed on the substrate;
• a second fixed contact formed on the substrate so as to surround the first fixed contact;
• a movable contact body to be pushed down to electrically connect the first fixed contact and the second fixed contact;
• and
• an adhesive member bonding the substrate and the movable contact body together,
• wherein the movable contact body comprises:
• at least one movable contact having an upwardly convex leaf-spring shape and being in contact with the second fixed contact;
• a cover member disposed so as to cover an upper surface of the movable contact;
• and
• a frame-shaped adhesive sheet having a base layer and an adhesive layers on both sides of the base layer, and arranged around an outside of the movable contact;
• and
• a holding member adhered to one of the adhesive layers, and disposed so as to face a lower surface of the movable contact, the holding member having a contact through-hole through which a top portion of the movable contact passes, wherein
• the frame-shaped adhesive sheet is a separate structure from that of the holding member,
• the holding member is an electrically insulating member having another through-hole into which at least part of the movable contact is inserted, the through-hole being disposed around the contact through-hole, and
• the second fixed contact includes a second contact base and a second contact projection, a difference in height between the second contact base and the second contact projection being larger than a thickness of the holding member.
