A FIRST AND SECOND HOLDERS 20 AND 30 ARE PROVIDED UP AND DOWN RELATIVE TO THE LINE CONNECTING BETWEEN A LEVER 40 AND A GUIDE MEMBER 50. THE LEVER 40 AND BOTH HOLDERS 20 AND 30 ARE ROTATABLY SUPPORTED BY A SUPPORT AXIS 11 OF A CASE 10 AND COAXIALLY CONNECTED TO EACH OTHER. PROJECTING PORTIONS 43 AND 44 FORMED ON THE UPPER AND LOWER FORWARD ENDS OF THE LEVER 40 ARE INSERTED INTO CAM HOLES 22 AND 32 OF BOTH HOLDERS 20 AND 30. WHEN THE LEVER 40 IS ROTATED, THE FIRST HOLDER 20 IS ARRANGED SUCH THAT ITS MOVABLE CONTACT 24 MAKES OR BREAKS CONACT WITH A FIRST TERMINAL 12 FOR SWITCHING A TURNING SIGNAL CIRCUIT, WHILE THE SECOND HOLDER 30 IS ARRANGED SUCH THAT ITS MOVABLE CONTACT 36 AND THE LIKE MAKE OR BREAK CONACT WITH A SECOND TERMINAL 62 FOR SWITCHING ANOTHER CIRCUIT SUCH AS A POSITION CIRCUIT. WHEN THE LEVER 40 IS PUSHED IN, EACH HOLDER IS PUSH-CANCELLED AND RETURNS TO ITS NEUTRAL POSITION. WITH THIS, TWO CIRCUITS CAN BE SWITCHED BY ONE LEVER AND BIASED WEAR-OUT AT EACH CONTACT PORTION CAN ALSO BE PREVENTED.(FIG. 1)
