いる。 In the figure, reference numeral 1 denotes a leaf spring for a movable contact, and the leaf spring 1 for a movable contact is formed of a flat plate material that has conductivity and elasticity and does not bend in a free state. At the center of the movable contact leaf spring 1, a synthetic resin support shaft 2 is molded and fixed to the outside of the movable contact leaf spring 1 with both ends protruding from both sides longer than the width of the movable contact leaf spring 1. The leaf spring 1 for the movable contact passes through the support shaft 2, and the support shaft 2
An operating protrusion 3 that stands upright on the surface of the movable contact spring 1 is integrally formed with the movable contact spring 1. In addition, the movable contact plate spring 1 has a first movable tongue piece cut and raised by a U-shaped groove at a predetermined position symmetrical about the support shaft 2 so that the base end is on the support shaft 2 side. 4 and a second movable tongue piece 5 are integrally formed on both sides. A first movable contact 6 and a second movable contact 7 are provided on the back surface of the tip of each of the first movable tongue piece 4 and the second movable tongue piece 5, respectively.
is provided. Furthermore, the leaf spring 1 for the movable contact
One end side of the movable contact plate spring 1 is bent to be substantially perpendicular to the movable contact plate spring 1, and a connection terminal 8 for electrical connection with the outside is formed at the bent end side. Plate spring 1 for movable contact configured in this way
is a U-shaped bearing part whose both ends are sandwiched and supported by cylinders 10a, 10b, 10c, and 10d provided inside the housing 9 so as to be freely curved, and both ends of the support shaft 2 are provided in the housing 9. 11 so as to be rotatably inserted into the movable contact plate spring 1 to regulate the horizontal reciprocating movement of the movable contact plate spring 1 and guide the vertical movement of the movable contact plate spring 1, thereby connecting the first movable contact 6 and the first fixed This prevents displacement of the connection positions of the contact 12, the second movable contact 7, and the second fixed contact 13. The first fixed contact 12 and the second fixed contact 13 are the first movable contact 6 and the second movable contact 7 of the movable contact leaf spring 1.
The first fixed contact 12 and the second fixed contact
Continuing from the fixed contact 13, connection terminals 14 and 15 that protrude outside from the housing 9 are integrally formed.

９内に回転自在に収納してある。 On the other hand, in the housing 9, an operating rotating body 16 is provided at a position where the tip of the operating protrusion 2 mentioned above comes into contact. A wavy protrusion with which the operating protrusion 3 engages is continuously formed on the outer periphery of the rotating body 16 for operation. The operating rotating body 16 is rotatably housed within the housing 9.
次に上述した実施例の動作を図面を参照しつつ
説明する。 Next, the operation of the above embodiment will be explained with reference to the drawings.

If the operating protrusion 3 is located at the
Since the operating rotating body 15 is not pressing the movable contact plate spring 1, the movable contact plate spring 1 is in a substantially straight state, and the first
The movable contact 6 and the first fixed contact 12 and the second movable contact 7 and the second fixed contact 13 are not in contact with each other.

る。 From this state, for example, when the operating rotary body 16 is rotated in the direction of the arrow X in the figure, the operating protrusion 3 is located in the wavy valley portion 16a on the outer periphery of the operating rotary body 16.
The tip of the groove 16a contacts the inclined surface 16b of the valley portion 16a. When the operating rotating body 16 is further rotated in the direction of the arrow X in the figure, the operating protrusion 3 is pressed by the inclined surface 16b of the valley portion 16a and tilted, and accordingly, the movable contact plate spring 1 is deformed and the operating protrusion 3 is tilted. It curves as shown by the broken line in Figure 1. Due to this bending of the movable contact leaf spring 1, the first movable tongue piece 4 lowers and the first movable contact 6 contacts the first fixed contact 12, thereby turning on. Further, when the operating rotary body 16 is rotated in the direction of the arrow X in the figure, the operating protrusion 3 overcomes the peak portion 16c and is located at the next valley portion 16d, returning to the orthogonal state and leaving the contacts 6 and 12 in the OFF state. becomes. This operation is repeated for each mountain portion by continuously rotating the operating rotary body 16, and the contact points 6 and 12 are connected and disconnected.

７と第２固定接点１３が断続される。 Conversely, when the operating rotating body 16 is rotated in the direction of the arrow Y in the figure, the operating protrusion 3 moves in the opposite direction to that described above.
is repeated, and the curved state of the movable contact plate spring 1 is reversed compared to when the operating rotating body 16 is rotated in the direction of the arrow X in the figure, and the second movable contact 7 and the second fixed Contact 13 is disconnected.

する。(Effects) As explained above, according to the rotary switch of this invention, by rotating the operating rotating body, the protrusions on the circumferential surface of the rotary body incline the operating protrusions, the leaf spring is curved, and the movable contact is Since the fixed contact is contacted, the operation of increasing or decreasing the change has directionality, and the operator can recognize the change in the period of the digital signal by the rotation angle of the operating rotary body. It has become something that can be done. In addition, in the present invention, the leaf spring for the movable contact is supported in the housing at both ends so that it can bend freely, and there is no bending, so it is easy to downsize, and the leaf spring for the movable contact has a flat plate shape in the free state. Since each movable contact is integrated and the operating protrusion is fixed to the leaf spring approximately in the center between each movable contact, the shape is simple and can be manufactured at low cost, and the number of required parts is reduced. This has the effect of requiring less.
