Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a rotary-operated pulse switch, in which the pulse signal generating section of the rotary-operated pulse switch and the moderating section provided for each single pulse during rotational operation are integrally constructed. The purpose of this invention is to improve the timing variations between moderation and pulse signals, and to rationalize the product including the set to which the pulse switch is installed by switching the circuit according to the direction of rotation inside the pulse switch.

In the case of a conventional rotary-operated pulse switch, the first
As shown in the figure, a metallic slider 3 having spring properties is caulked to a rotary insulating plate 2 attached to an operating shaft 1, and is formed by printing or etching on an insulating substrate as shown in Fig. 2. Alternatively, it has a signal generating section that generates a pulse signal by sliding on the substrate 4, which has comb-shaped circular contacts 8 and 9 integrally formed with an insulating molding material, and comb-shaped circular contacts 8 and 9. A moderation plate 7 is attached to a cover 6 attached to a base plate 4 and has a radial groove 7a, and a click spring 5 is provided for each single pulse signal and is caulked to the operating shaft 1 and has a spring property to rotate together with the operating shaft 1. Since the moderation section and the moderation section are not integrally configured, variations tend to occur in the timing between the moderation and the pulse signal during rotation operation, and as a measure to improve the variation, it becomes difficult to reduce the cost because it leads to severe parts precision. In addition, in the conventional pulse switch, as shown in FIG. A deviation in a certain direction is provided at the angle of . As shown in Fig. 3, switching the pulse signal generation circuit depending on the direction of rotational operation causes a time lag in the pulse waveform during operation, which is determined by the circuit inside the set to which the pulse switch is installed, and the switching is performed. This is a method to do this. Therefore, if it becomes possible to switch the pulse circuit in the direction of rotation inside the pulse switch, the cost of the set used for the pulse switch can be reduced.

In addition, in FIG. 2, T ₁ to _{T 3} are terminals,
The terminals T ₁ and T ₃ are the comb-shaped circular contacts 9 and 9, respectively.
The terminal T ₂ is electrically connected to the annular current collector 10 . here,
Connection part between current collector 10 and terminal T ₂ and circular contact 9
Insulating coatings 11 and 12 are provided at the connection between the terminal T1 and the terminal _T1 , as shown by hatching in FIG.

The present invention has been devised in view of the above points, and one embodiment thereof will be described below with reference to FIGS. 4 and 5.

First, the pulse signal contact plate 13 is made of a conductive material that is formed by printing or etching on an insulating substrate radially from its center, or by integrally molding with an insulating molding material. It has a circular contact 14 with comb-like contacts 14a, and moderation grooves 15 formed radially from the center of the contact plate 13 in the insulating portion between each comb-like contact 14a. This contact plate 13 for pulse signals is attached to a rotating plate 16 made of an insulating molded product, and the rotating plate 16 is attached to an operating shaft 19 held in a bearing 18 into which an insulating mounting plate 17 is caulked. The mounting plate 17 has a metal contact plate 2.
0, 21 and the contact plate 13 with a metal rivet 2 for attaching a metal contact 22 that has a spring property and comes into contact with the contact plate 13.
3 is attached, and a metal contact piece 24 that can freely rotate about the caulking stud 23 is inserted together with a spring 25. Further, a contact stud 26 made of a conductive material such as metal is attached to a hole at the tip of the contact piece 24, and a sliding dowel (spherical surface) at the tip of the contact stud 26 normally enters the moderation groove 15. Contact piece 2 by spring 25
4 to the contact plate 13. The contact plate 13 and the rotary plate 16 holding it are mounted on a housing 2 attached to a mounting plate 17.
covered by 7.

Now, when the operating shaft 19 is rotated in the direction of arrow A in FIG. Therefore, the contact piece 24 rotates about the stud 23 in the direction of arrow B and comes into contact with the contact plate 20.

In this case, since the contact stud 26 is not in contact with the comb-like contact 14a of the circular contact 14, it is OFF between _T11 and _T12 . Next, when the operating shaft 19 is continued to be rotated in the direction of arrow A, the contact piece 24 contacts the contact plate 20 and cannot be rotated, and the contact stud 26 pushes up the spring 25 via the contact piece 24 and rotates in the direction of arrow A. A contact stud 2 is attached to the moderation groove 15 adjacent to the position in the opposite direction.
6 moves. At this time, a feeling of moderation occurs, and the contact studs 26 pass over the comb-shaped contacts 14a, so that the terminals T ₁₁ to _{T 12} are momentarily turned on. When the operating shaft 19 is rotated in the direction of the arrow A in this manner, one pulse signal is generated between the terminals T ₁₁ to T ₁₂ every time one mode is generated. Furthermore, when the operating shaft 19 is rotated in the direction opposite to the direction of the arrow A, one pulse signal is similarly generated between the terminals T ₁₂ to _{T 13} for each mode.

The present invention is configured as described above, and has the following effects.

(1) The moderation section and the pulse signal generation section for rotational operation are integrated into an integrated structure to provide an inexpensive rotary operation type pulse switch with small variations in moderation and pulse signal timing.

(2) By switching the pulse signal generation circuit inside the pulse switch depending on the direction of rotation, the structure can be streamlined, including the set in which the pulse switch is installed.
