Description

[Detailed Description of the Invention] The present invention relates to a rotary slide switch.

Conventionally, a switch case is made up of an insulating terminal board with a plurality of fixed terminals arranged on one side, and a slider made of an insulating material is slidably placed in a sliding hole, and the front side of the case. It consists of a fixed plate provided on the fixed plate, a manually operated rotating shaft supported by this fixed plate, and an insulator provided at the tip of this rotating shaft, and an opening extending spirally into the wall of the rotating shaft. The slider also includes a cylindrical body that has a cylindrical body and can rotate integrally with the rotating shaft, and a pin-shaped body provided on the protrusion at the end of the slider is fitted into the cylindrical opening,
A rotary slide switch in which a pin-shaped member of a slider is slidably fitted into an opening groove of a tongue extended from a case is known, for example, from the 1970s.
It is known from Publication No. 15162, etc.

However, in this rotary slide switch, the protrusion of the slider is inserted into the cylindrical body, and then the protrusion of the slider is inserted through the opening groove of the tongue and the opening provided in the wall of the cylindrical body. Since it has a structure in which a pin-shaped body is implanted in the part, it is troublesome to assemble and has a large number of parts, which is disadvantageous in terms of cost.

The present invention relates to a conventional rotary slide switch which is configured such that the slider slides in accordance with the rotation of the rotating shaft by engaging a pin-like body on the slider side with the spiral groove of the manually operated rotating shaft. In view of the problems, an object of the present invention is to provide a rotary slide switch that is extremely easy to assemble, has a small number of parts, and is inexpensive.

Hereinafter, several embodiments of the rotary slide switch according to the present invention will be described in detail with reference to the drawings.

By being caulked and engaged at 1c, the case 1
It is designed to be installed in Further, the terminal board 22 has a protrusion in which a recess 22B is formed at approximately the center of the width of the terminal board 22 and at the front side, in which a coil spring 26 and a steel ball 27 for locking the detent are disposed. A section 22C is provided. 25
2 is a rotary operation shaft, and one end extending outside the case 21 has a rotary operation knob 25A and a mounting screw portion 25B, and the other end disposed inside the case 21 is made of a synthetic resin material and has a day tent engagement member. The stop part 25E and the actuating part 25D pass through an integrally molded cylindrical body, and the other end is rotatably supported by a shaft support part 21D integrally molded from the upper wall part 21A. The intermediate portion thereof is also rotatably supported by a fixed plate 24. The detent locking part 25E is provided with a plurality of detent engaging recesses 25e at positions corresponding to the protrusions 22c of the terminal board 22, and the steel balls are activated by the biasing force of the coil spring 26 housed in the recess 22B. 27 is pressed into engagement with the detent engagement recess 25e. or,
A spiral groove 25C is provided on the outer peripheral surface of the actuating portion 25D. The slider 29, which is slidably disposed within the case 21, has a housing recess 29A that houses a movable contact piece 30 that is switch-connected to the fixed terminal 23 on the terminal board 2, and has a housing recess 29A at one end that houses the movable contact piece 30 that is connected to the fixed terminal 23 on the terminal board 2. An extending portion 29B is provided that extends to a position corresponding to the portion 25D. The operating portion 25 is provided on the surface of the extending portion 29B that corresponds to the operating portion 25D.
Engagement pin portion 3 engaged with the spiral groove 25C of D
