摘要:
A member for a push button switch that has a small thickness, high durability, and excellent click feeling and can be manufactured at low cost. The member for the push button switch includes one or more key tops, a metal sheet including at least holes that correspond to positions of the key tops, and an elastic sheet that is provided on the metal sheet so as to be positioned on the same side as or opposite side to the key tops. The elastic sheet is fitted into the holes and comes in contact with the key tops at positions of the holes. The elastic sheet includes a urethane film or polycarbonate, and a silicone rubber, which are laminated in a thickness direction of the metal sheet.
