Claims

[Claims for Utility Model Registration] A switch equipped with a drive plate that moves in parallel during opening and closing operations, and a rod-shaped movable contact whose base is supported by the drive plate and whose tip slides into and out of contact with a fixed contact. two first bearing bodies each having a convex or concave spherical surface on one side and having a flat surface on the other side in contact with both side surfaces of the drive plate, and the spherical surface on one side; two second bearing bodies each having a concave or convex spherical surface with the same curvature as the second bearing body, and each of the second bearing bodies is disposed such that the two spherical surfaces are in contact with the spherical surfaces of the two first bearing bodies; a through hole formed through two bearing bodies, one of the first bearing bodies, the drive plate, the other of the first bearing bodies, and the other of the second bearing bodies; and each of the through holes. A switch comprising: an insertion shaft inserted into the insertion shaft; and pressing means provided at an end of the insertion shaft to press the other second bearing body toward the drive plate.
