[Problems to be solved by the device]

 However, since two touch-sensitive springs 5 that engage with the tooth portion 8 of the rotor 4 are separately used, if the contact 3 and the contact 3 are sequentially assembled into the insulator 1, three assembly parts and man-hours are required at this assembly location. There is a problem.

Therefore, an object of the present invention is to provide a dip switch in which the number of parts and the number of assembling steps are reduced.

[0007]

[Means for Solving the Problems]

 According to the present invention, an insulator, a contact member arranged on one surface of the insulator, a conductive contact facing the contact member on the one surface, and a pivotable movement about an axis directly crossing the one surface A dip switch including a rotor that is axially supported by the insulator and that causes the contact to come into contact with and separate from the contact member by the rotation; Thus, a dip switch is obtained in which the feel spring and the contact are integrally connected to each other.

[0008]

[Action]

 To assemble the DIP switch, first place the contact on one side of the insulator. Next, the rotor is pivotally supported on the shaft. Then, the ring is provided on the rotor. The rotor engages with the tactile springs that are integrally provided upright on both edges of the contact, and the rotation causes a modest switching operation.

【Example】

 An embodiment of the DIP switch of the present invention is shown in FIGS. In this embodiment, the same parts as those in FIGS. 3 to 5 will be described with the same reference numerals.

With reference to FIGS. 1 and 2, the dip switch includes an insulator 1, a plurality of contact members 2 arranged on one surface of the insulator 1, and a conductive member facing the contact members 2 on one surface. Contact 3 and rotor 4. The rotor 4 is pivotally supported by the insulator 1 so as to be rotatable around one axis which is orthogonal to one surface. Further, the rotor 4 rotates to bring the contact 3 into contact with and separate from the contact member 2. A touch spring 5 is pressed against the rotor 4. The touch spring 5 is pressed against the rotor in a direction parallel to one axis so as to press the rotor in the radial direction.

More specifically, each contact member 2 is connected to a plurality of lead terminals 6 and is connected to an external electric circuit. These contact members 2 are switched by the rotation of the rotor 4. A part of the lead terminal 6 is embedded in the insulator 1. The contact 3 has a plurality of contact spring pieces 7. The contact 3 is obtained by punching and bending a thin conductive plate. On the outer circumference of the rotor 4, a plurality of concavo-convex tooth portions 8 are formed to maintain the moderation of rotation. Further, two feeler springs that are engaged with the tooth portions 8 to improve the sense of rotation are held by the insulator 1. The feel spring 5 and the contact 3 are integrally connected to each other. The rotor 4 has a ring 9 on the upper surface of the tooth portion 8 and is pressed by an upper lid 10. The insulator 1 and the upper lid 10 form a case.

In this DIP switch, the rotor 4 has a feeling of rotation by the feel spring 5, and the contact member 2 and the contact spring piece 7 are selectively brought into contact with each other. Switching is carried out. The upper surface of the rotor 4 is pressed by the ring 9 and the upper lid 10. The insulator and the upper lid 10 form a case.

Further, on one surface of the insulator 1, a shaft 11 protruding from the central portion of the one surface is projected. The rotor 4 is axially supported on the shaft 11. The teeth 8 formed on the outer periphery of the rotor 4 are pressed in the radial direction by the feel spring 5. Further, an upper lid 10 is placed on the upper surface of the tooth portion 8 via a ring 9.

To assemble this DIP switch, the contact 3 is placed on one surface of the insulator 1. At this time, since the feel spring 5 and the contact 3 are integrally connected to each other, they can be assembled in one step. Next, the rotor 4 is pivotally supported on the shaft 11. Then, the ring 9 is provided on the rotor 4, and the upper lid 10 is covered on the insulator 1.

[0015]

[Effect of the device]

 As described above, in the conventional assembly, the contact required three steps of assembling two parts of the two feel springs. According to the present invention, the contact and the feel spring are integrally formed. Since it is a single component, the assembly process is a single process, and the number of parts and the number of assembly processes are reduced, resulting in a reduction in price.
