In addition, the fixed contacts 4 and 5 are disposed in the recesses 1e formed in the bottom wall 1a, and have the conductive patterns 2 and 3 and the step D so that the movable contacts 8 are recessed. Since it is made to hold | maintain in (1e), holding | maintenance of the movable contact 8 is simple and reliable is obtained.

In addition, one operating member 13 capable of rotating and moving in the axial direction is provided, and the encoder E is operated by the rotating operation of the operating member 13, while the operating member 13 moves in the axial direction. Since the push switch P is operated by one operation, the encoder E and the push switch P can be operated by one operation member 13, and a thing with good operability is obtained.

Further, a first hoop material (F1) made of a conductive metal plate on which ring-shaped conductive patterns (2,3) for encoders is formed, and a metal made of conductive metal plate on which fixed contacts (4,5) for push switches are formed. 2 having the hoop material F2, and the first and second hoop materials F1 and F2 are disposed to face each other with the fixed contacts 4 and 5 positioned at the center of the conductive patterns 2 and 3, A portion of the conductive patterns 2 and 3 and the fixed contacts 4 and 5 are exposed from the surface of the bottom wall 1a of the insulator gas 1 to expose the conductive patterns 2 and 3 and the fixed contacts 4 and 5. At the same time, since the manufacturing method embedded in the insulating gas 1 was carried out, the conductive patterns 2 and 3 having different shapes and the fixed contacts 4 and 5 were processed in parallel, and then the first and second hoop materials F1 were processed. And F2) can be arranged to face each other. Therefore, both of them can be processed in the same production line, so that the production is easy.

In addition, since the conductive patterns 2 and 3 and the fixed contact point 4 have a step D embedded in the bottom wall 1a, the gap between the first and second hoop materials F1 and F2 is used. What is necessary is just to form the insulated gas 1 in the state which made it to have, and the manufacture is simple, and the small insulated gas 1 is obtained.

Moreover, since the fixed contact 4 and 5 were embedded in the recessed part 1e formed in the bottom wall 1a, and it was set as the manufacturing method which provided the conductive patterns 2 and 3 and the step D, it is simple, It is possible to provide a production capable of maintaining a reliable movable contact 8.

In addition, the conductive patterns 2 and 3 and the fixed contact 4 and 5 are formed in one hoop member F, and the first and second hoops are formed by cutting or bending the one hoop member F. FIG. Since the materials F1 and F2 are formed and the first and second hoop materials F1 and F2 are made to face each other, they are fixed with the conductive patterns 2 and 3 having different shapes from the same material.
