A lever switch device comprising: a movable element which is supported rotatably in a case about a rotational axis; first and second movable plates (41, 43) which are disposed so as to move along a pole plate on the case side in a direction which intersects the rotational axis of the movable element at right angles to thereby be caused to perform a contacting action relative to the pole plate; and a control lever supported rotatably on the movable element about another rotational axis, said control lever comprising: first and second levers (13, 15) which are supported so as to swing and rotate freely relative to the case and disposed concentrically in the control lever so as to rotate about axes of the first and second levers (13, 15) on the movable element, characterized by comprising: first and second fitting portions (45, 47) which are provided on the first and second movable plates (41, 43) and which lie adjacent across the rotational axis of the movable element; first and second arms (19, 23) in which proximal portions are supported on the first and second levers (13, 15) so as to rotate on axes which are at right angles to the lever axes of the first and second levers along the lever axes and so as not to rotate about the lever axes, and distal end portions lie adjacent across the rotational axis of the movable element and fit in the first and second fitting portions (45, 47); a restriction wall which is formed between the first and second arms (19, 23) so as to restrict the first and second arms from moving in the direction of the lever axes during the rotation of the first and second levers (13, 15) about said another rotational axis relative to the movable element; and engagement walls (45a, 45b, 47a, 47b) which are formed on the first and second fitting portions (45, 47) so as to be brought into engagement with the first and second arms (19, 23) as a result of rotational movement of the first and second arms by axial rotation of the first and second levers (13, 15) about the lever axes to thereby cause the first and second movable plates (41, 43) to perform the contacting action. a movable element which is supported rotatably in a case about a rotational axis;
