Abstract
A switch device may have a restriction member provided between a support portion and a fixed contact point portion of a polar board for restricting movement of a movable piece to the polar board. The restriction member may have a set height from the polar board such that the restriction member abuts on the movable where the fixed contact point reaches a predetermined height from the polar board due to wear. The movable piece may be supported by the support portion to be displaceable in the longitudinal direction such that when one side of the movable piece makes contact with the first fixed contact point, in a case where the restriction member makes contact with the movable piece, the movable piece may be displaced in the longitudinal direction on a basis of the contact position with the restriction member to be disconnected from the first fixed contact point.
