断されることを特徴とするスイツチ。 A switch in which a movable contact piece attached in conjunction with a common fixed contact piece is moved by a pressing operation against a reversal spring of a push button and selectively connected to a main fixed contact piece, and the movable contact piece is attached to the common fixed contact piece. The proximal end of the conductive leaf spring is fixed, one end of an insulating abnormality detection piece is attached to the free end of the leaf spring, and the other end of the abnormality detection piece is normally locked to the lower part of the push button. This presses and biases the leaf spring to establish an electrical connection between the common fixed contact piece and the movable contact piece in a normal state, and when the movable contact piece and the main fixed contact piece are welded together when the push button is pressed. . A switch, wherein the abnormality detection piece enters a lower part of the push button, thereby cutting off electrical connection between the common fixed contact piece and the movable contact piece.
