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: A push switch includes: a hollow housing having an inner circumferential surface formed with a guide part; an operation button formed with a first ratchet tooth; a cam follower including a cam part, and a second ratchet tooth, and being movable up and down in an axial direction and rotatable in a circumferential direction; a first spring; an engagement piece engaged with the cam follower; a movable contact; a metallic contact member rotatable integrally with the cam follower; a fixed terminal including contacts to be switched by rotating the contact member; and a base on which the fixed terminal is fixed. The contact member defines a through hole at a rotation center of the contact member. The base includes a rotation axis part inserted in the through hole and serving as the rotation center of the contact member.

Abstract: A slide switch includes a slider, a case into which the slider is inserted, performing switching by a sliding operation of the slider, cushioning (an upper part, a left part, and a right part) provided at contacting places in the side of the slider where the slider and the case come into contact by the sliding operation of the slider for relieving the contact, and a cushioning holding member for integrally supporting the cushioning, wherein the case has case inner faces on which the slider slides, and which face each other along a horizontal direction, one of the inner faces of the case has a positioning part for positioning the slider at three positions, and the other of the inner faces of the case has a positioning part for positioning the slider at two positions. The cushioning can reduce generation of vibration noise of the slide switch due to vibration of a vehicle under running and operation noise due to a switching operation to improve an operation feeling of the vehicle.

Abstract: A pushbutton switch includes an upper case (1) having a cylinder portion (1b) and a button (3) which is capable of a sliding motion along the cylinder portion (1b). A rotor (5) having a flange (1a) at the bottom thereof performs a sliding reciprocating motion while rotating in the predetermined direction responding to reciprocating motion of the button (3) by setting the axis of rotation as the long axis of the cylinder portion (1b). A contact segment (4) is inserted in the rotor 5 and stationary terminals (2a, 2b, and 2c) oppose the contact segment (4). The rotor (5) carries out a predetermined angle rotation for every reciprocating motion of the button (3) to effect alternating ON/OFF switching action. Arms (4a) curve toward stationary terminals (2a, 2b, and 2c) and elastically buckle in accordance with the variation in distance between stationary terminals (2a, 2b, and 2c) and the rotor(5) when the rotor (5) performs a sliding reciprocating motion.
