摘要：PROBLEM TO BE SOLVED: To securely switch a contact by preventing shifting of a position of a pressing spring from a center even when a V-shaped groove of a plate spring is deformed, and reducing displacement of a movable contactor and movable contact.SOLUTION: The contact switch performs switching operation by making a movable contact part structure contact with or separate from a fixed contact in response to an excitation state to a coil. The movable contact part structure includes: the movable contactor having a movable contact contacting with the fixed contact; and a cross bar which sandwiches the movable contactor by a pressing spring support having a truncated pyramid shape projection and the plate spring having the V-shaped groove corresponding to the projection of the pressing spring support, and moves the movable contactor parallel in response to the excitation state to the coil. The pressing spring support and the plate spring are arranged so that at least two points of an upper side of the truncated pyramid shape projection of the pressing spring support are in contact with an inner wall surface of the V-shaped groove of the plate spring when viewed from a front face in a longitudinal direction of the movable contactor, and the upper side of the truncated pyramid shape projection of the pressing spring support is in contact with the inner wall surface of the V-shaped groove of the plate spring when viewed from a front face in the lateral direction of the movable contactor.
