In a switch in which a fixed contact is disposed in a case and a movable contact piece is tilted by a converter tilting in the case to switch an electric circuit, a projecting piece is formed on the upper surface and the upper and side surfaces of the projecting piece are formed. A connector having a recess is fitted to the converter, and a lever having a sliding rod is coupled to the connector via an elastic member, and the lever is in a direction perpendicular to the tilting operation direction of the connector. The lever can be tilted, and the lever is held in an upright position or a tilted position by engagement of the recess and the sliding rod, and is stored so as not to protrude from the cover when in the tilted position.

According to the present invention, the following effects can be achieved.
(1) Although the lever protrudes from the cover and stands upright at the time of operation, the lever can be tilted and stored so that the lever does not protrude from the upper surface of the cover after the operation.
(2) The design can be improved because the lever can be stored in the cover without protruding.
