Abstract: A manual valve device including: a plurality of air bags provided inside a vehicle seat; a valve main body including a plurality of flow passages communicating with the plurality of air bags, respectively; a plurality of valve bodies movable inside the valve main body so as to open and close the plurality of flow passages, respectively; a plurality of valve shafts coupled to the plurality of valve bodies, respectively, and configured to be manually operated to move the plurality of valve bodies in a stroke; and an operation lever configured to press any one of the plurality of valve shafts or any combination of the plurality of valve shafts in an axial direction, in which the operation lever includes an adjustment mechanism configured to adjust an air flow rate per unit time flowing in the plurality of flow passages by changing a stroke amount in the axial direction.

Abstract: A multifunction switch has a switching function for an electrical contact switch and a switching function for a mechanical element. The multifunction switch includes a swingable control body having a control pin, a movable contact coming into contact with the control pin, and a movable element having the control pin running therethrough and supported so as to be swingable. With the control pin being swung, the movable contact is pressed by the control pin to come into contact with a fixed contact and the movable element is swung by the control pin to implement mechanical switching for an additional element.

Abstract: Provided is a multifunction switch (1) having a switching function for an electrical contact switch and a switching function for a mechanical element. The multifunction switch (1) includes a swingable control body (20) having a control pin (22), a movable contact (31) coming into contact with the control pin (22), and a movable element (40) having the control pin (22) running therethrough and swingably supported. With the control pin (22) being swung, the movable contact (31) is pressed by the control pin (22) to come into contact with a fixed contact (32) and the movable element (40) is swung by the control pin (22) to implement mechanical switching for an additional element.
