Claims

[Claims for Utility Model Registration] A key top whose central portion is supported with respect to a printed circuit board, and each push-down portion extending on both sides of the central portion can rotate about the central portion as a fulcrum to approach and separate from the printed circuit board; a skirt part that can be deformed by pressing down a pressing part; and a movable contact part disposed within the skirt part that can come into contact with and separate from a fixed contact part on the printed circuit board, and each pressed part of the key top of the printed circuit board In the structure of the seesaw switch, the seesaw switch is provided with contact rubbers respectively provided corresponding to the contact rubbers, wherein a contact portion of the contact rubber that contacts the push-down portion is formed to protrude thinly upward, and a contact area with the push-down portion is formed. The structure of the seesaw switch is characterized in that it is made smaller.
