The utility model discloses further set up to form the round hole on the swinging member, form waist type hole on the button, the pivot passes round hole and waist type hole in proper order.

The kidney-shaped hole enables the button to rotate and vertically move on the pivot, and the round hole enables the swinging piece to rotate on the pivot.

The utility model discloses it is provided with three to set up to the static contact, form two movable contacts on the movable contact, the movable contact forms the electricity with the static contact respectively along with the swing action and is connected.

When the button is shifted, the two movable contacts are electrically connected with the two static contacts to form conduction of a left steering loop or a right steering loop.

This practicality further sets up to be provided with first spring between kicking block and the button.

This practicality further sets up to be provided with the second spring between gear piece and the swing piece.

The utility model is further provided with a third spring between the movable contact spring and the swinging piece.

The first spring is used for resetting after the button is pressed; the second spring enables the gear block to be stably positioned in the gear groove; the third spring provides an over travel function for the movable contact piece, so that the movable contact can be in interference fit with the static contact piece, and the reliability of electric connection is ensured.

This practicality further sets up to the upper end of button and passes buckler and clamp plate and extend to the outside.

This practicality further sets up to swing the piece and is the fan-shaped, and the diapire in pendulum hole forms the V profile.

The V-shaped surface enables the button to be pressed smoothly, the fan-shaped swinging piece reduces the overall height of the steering switch, and the internal structure is more compact.
