Abstract

PURPOSE:To switch many circuits in sequence and improve the operability by providing at least two movable contact members with different distances to a fixed contact on movable pieces corresponding to one rotation side of an operation button and bringing the different contacts into contact in sequence so that the two movable contact members are brought into contact with the fixed contact with a time difference. CONSTITUTION:When one side of an operation section 39 is depressed, an operation button 26 is rotated clockwise using the axis as a fulcrum, and movable pieces 59 and 60 are pushed down by a control projection 42. At this time the movable contact section 34A of a movable contact member 34 is largely protruded downward by the size X then the movable contact section 33A of a movable member 33, thus the movable contact section 34A is first brought into contact with a fixed contact 71, and a fixed contact 71A and a fixed contact 71B are set to the conductive state via the movable contact section 34A. This switch can be used in the time difference mode to control individual circuits, thereby the operability is improved.

The seesaw type switch 25 configured in this way is
The operating button 26 can be rotated in the left-right direction using the pivot 74 as a fulcrum, and when one side of the operating section 39 is pushed from the direction shown by arrow C in FIG. Rotated clockwise. At this time, the pivot portion 40 is also rotated together and displaced with respect to the ball 30, so that the center recess 45 is released from the ball 30 due to this displacement, and the outer circumferential recess 44 is rotated around the clock 41 with the outer peripheral recess 44 being arranged correspondingly to the ball 30. rotated in the direction. As shown in this state in FIG. 3, the center recess 45 is released from the ball 30, and then the outer peripheral recess 44 is disposed correspondingly to the ball 30. Further, during this movement, the difference in level between the central recess 45 and the outer circumferential recess 44 provides an operational feel to the operator's fingers, and at the same time, the movable pieces 59 and 60 are pushed down by the control protrusion 42. At this time, the movable contact portion 34A of the movable contact member 34 protrudes downward by a distance X by a larger amount than the movable contact portion 33A of the movable contact member 33, so the movable contact portion 34A first contacts the fixed contact 71, The fixed contact 71A and the fixed contact 71B are brought into conduction via the movable contact portion 34A. This state is also shown in FIG. Further, if the operation button 26 is further moved clockwise from this state,
Then, as shown in FIG. 4, the inner edge 44A of the outer circumferential recess 44 collides with the ball 30, and the operating button 26 cannot be rotated any further, and the rotating contact portion 3
3A is brought into contact with the fixed contact 70.

When the operation button 26 moves downward until the movable contact member 33 contacts the fixed contact 70, the excessive displacement force applied to the movable contact member 37 is caused by the bending deformation of the movable piece 60 and the attachment of the auxiliary coil spring 38. The force is absorbed by the movable contact member 34 sliding against the movable piece 60 against the force, thereby reducing mechanical fatigue of the movable piece 60. Also, on the movable contact member 33 side, when an extra downward rotational force is applied after the movable contact member 33 contacts the fixed contact 70, the sliding of the movable contact member 33 against the movable piece 59 similarly occurs. The movable piece 59 absorbs excess displacement force, thereby reducing mechanical fatigue of the movable piece 59.

An operation button whose middle part of a pivot part protruding from the lower side of the operation part is rotatably supported by a base and rotates from side to side about this support part as a fulcrum; a conductive plate spring having a movable piece at both ends that is pressed down by rotation of the operation button and urges the operation button to a neutral position, and a movable contact member attached to the movable piece; and the pressed down movable contact. A seesaw-type switch comprising a fixed contact with which a member abuts, the movable piece corresponding to one rotating side of the operation button having at least two contacts at different distances to the fixed contact. A seesaw type switch characterized in that the movable contact member is provided, and the two movable contact members abut against the fixed contact with a time difference.
