FIG. 5A shows a plan view of the first case 1 as seen from the inside surface, and FIG. 5B shows a plan view of the first case 1 seen from the outside surface. Also, second case 2
FIG. 6 shows a plan view from the inside surface.

The first case 1 has a front wall portion 3 and a rear wall portion 4.
The side wall portion 5 and the upper wall portion 6 are integrally molded from synthetic resin material, and each wall portion 3, 4, 5 has a plurality of engaging portions 1.
0 is formed. Also, the second case 2 is
It is integrally molded with a synthetic resin material so as to form a side wall opposite to the side wall 5 of the case 1, and the first When assembled into the case 1, an elastically deformable engaging arm portion 2A is formed that extends toward the engaging portion 10. The engaging portion 10 provided in the first case 1 has a groove portion 10A having a depth approximately equal to the wall thickness of the engaging arm portion 2A of the second case 2, and a groove portion 10A that protrudes from the inside of the groove portion 10A. This engaging claw portion 10B is composed of an engaging claw portion 10B.
is formed of an inclined surface that gradually descends toward the side into which the engaging arm portion 2A of the second case 2 enters.
Further, the engagement arm portion 2A of the second case 2 that is engaged with the engagement portion 10 of the first case 1 has an engagement hole 2a formed in the middle thereof. The engaging portion 10 of the first case 1 and the engaging arm portion 2A of the second case 2
means that when the second case 2 approaches the first case 1 so as to close the open side of the first case 1 with the second case 2, the first case 1
The engaging arm portion 2A of the second case 2 advances along the inclined surface of the engaging claw portion 10B in the engaging portion 10 with elastic deformation, and engages with the tip of the engaging claw portion 10B. When the engagement hole 2a of the engagement arm 2A reaches and slightly passes the tip, the engagement arm 2 that has been elastically deformed

Since A is in the groove 10 of the first case 1, the wall surfaces of the engaging parts 10 of the first case 1 to which the second case 2 is assembled are flush with each other. It's summery.

Conversely, when disassembling the assembly of the first case 1 and the second case 2, the distal end portion of the engagement arm 2A is elastically deformed outward, and the engagement of the engagement arm 2A is removed. By removing the mating hole 2a from the engaging claw portion 10B and separating the second case 2 from the first case 1, it is possible to easily disassemble the case.

Therefore, when such an engagement mechanism is adopted, the first case 1 and the second case 2 can be easily assembled without using adhesive or the like, and it is easy to disassemble them. Since no adhesive or the like is used during assembly, assembly is easy.

The above description has been made regarding the structure in which the first case 1 and the second case 2 can be assembled and disassembled.

The front wall of the switch, which is formed by the first case 1, the second case 2, and the terminal board 15 as described above, is formed by the front wall part 3 of the first case 1 and the second case 2.
The front wall has a window hole 3C for allowing a lever 9 of a rotation operation member 8 to extend outward, and a window hole 3C for allowing the switch to be connected to a machine frame (not shown) of the equipment. ) are formed with mounting portions 3A and 2B for mounting. The window hole 3C is formed by cutting out a part of the front wall 3 of the first case 1 in a rectangular shape, and closing the open side of the notch with the second case 2. The window frame is formed by extending into the notch. Also, mounting parts 3A, 2B
are provided with cutouts 3B and 2D, respectively.
Further, the mounting portions 3A and 2B are provided on both left and right sides of the window hole 3C, and their heights are located above and below the window hole 3C. A reinforcing metal plate 16 is immediately behind the mounting portions 3A and 2B, which are continuous from the front wall and formed on the same surface as the front wall.
Elongated holes 3E, 2 into which arm portions 16A, 16B of
E are formed respectively, and long holes 3E and 2E are formed.
Grooves 2F and 3F are provided in series with the long holes 3E and 2, respectively.
A part of the end face of the metal plate 16 fitted into the hole E is received to stabilize the holding of the metal plate 16 disposed on the inner surface of the front wall. Further, the metal plate 16 has arm portions 16A, 16

The upper and lower rotation ends of the upper and lower rotation ends do not contact each other, but the upper and lower edges of the window hole 3 of the first case made of synthetic resin material are used to regulate the balance. This structure alleviates the impact noise with the lever 9 and also provides an insulation effect. In other words, in the case of lever switches, etc., the switching lever is generally made of metal, etc., but when the switching lever is made of metal like this, if the lever hits the metal frame at the end of rotation, ,
The striking sound becomes louder. In addition, the first case is made of a synthetic resin material so that the collision at the end of the rotation of the lever 9 is made of a synthetic resin material. 1 window hole 3
By doing so, it alleviates the impact of a collision. Furthermore, in electrical equipment to which this type of lever switch is assembled, grounding is often done at the machine frame, but if the lever 9 is made of a metal material, sometimes there is a grounding point that is connected to the lever 9. Although electrical leakage may occur through the capacitor, this type of electrical leakage accident can be prevented from occurring.

Then, the metal plate 16 has the arm portion 16A fitted into the elongated hole 3E inside the front wall portion 3 of the first case 1, and the arm portion 16A inserted into the elongated hole 2E of the second case 2.

In this case, screw holes 16D of the metal plate 16 are arranged at 3B and 2B, respectively, and the metal plate 16 is fixed to the machine frame of the device with screws using the screw holes 16D. At this time, the front surfaces of the mounting portions 3A and 2B of the cases 1 and 2, which are made of synthetic resin material, serve as washers. In this switch, the front surface of the switch is reinforced with a metal plate 16 to address the problem of strength when the case is made of a synthetic resin material that can reduce costs. Because of this, it is stable in terms of reliability.

In addition, a mounting part 3A, which is mounted on the mounting surface of the device,
In the case of 2B, the switches are installed on both the left and right sides with the window hole 3C as the center, and the heights are located above and below the window hole 3C. Even if the two mounting parts 3A,
Since the acting force is applied almost uniformly to 2B, it is possible to withstand large external forces with fewer fixing points.

The operation of the switch according to the present invention constructed in this manner will be explained using FIG.

The state shown by the solid line in FIG. 3 shows the state in which the lever 9 of the rotary operating body 8 is in an intermediate position, and in this state, the protruding portion 19C of the rotary operating body 8 is 3 installed on the inner wall of case 2
It is elastically engaged with the intermediate recess 13 of the two detent recesses 13. Then, when an upward rotation biasing force is applied to the lever 9 from this state, the rotation operation body 8 is rotated clockwise as a whole, and the operation body 8 is rotated clockwise as a whole.
The slider 7, in which the connecting arm 18 and the connecting portion 7A are freely engaged, is slid to the left 7'' position in FIG. 3, and the movable terminal 22 that slides together with the slider 7 performs contact switching. The rotation operation body 8 is rotated until the lever 9 comes into contact with the upper end of the window hole 3C of the first case 1. The protruding portion 19C of the operating body 8 is locked to the detent recess 13 on the rotation direction side among the three detent recesses 13, and the rotation switching is maintained.Then, the lever 9 is moved downward. When the rotation biasing force is applied, the rotation operating body 8 rotates counterclockwise as a whole, and once the detent is locked in the intermediate position shown by the solid line in FIG. 3, the lever 9 is further moved downward. When it is rotated, it is rotated until it comes into contact with the lower end of the window hole 3C of the first case 1, and the protrusion 19C of the rotation operation body 8
is locked to the detent recess 13 on the rotating direction side among the three detent recesses 13,
The rotation switching is maintained. When the rotation operation body 8 is rotated by operating the lever 9,
As described above, since the connecting arm 18 of the rotation operating body 8 and the connecting portion 7A are freely engaged, the slider 7
is also slid to the right position 7' in FIG. 3, and the movable terminal 22 performs contact switching. In this manner, by rotating the lever 9, the rotating operating body 8 is moved to the protruding portion 1 by the spring action of the spring portion 19.
9C is rotated while being locked in the daytent recess 13, and the slider 7 also slides by a predetermined amount. A plurality of hemispherical protrusions 2 are provided on the surface that comes into sliding contact with the substrate 15.
Since the slider 8 is provided, the contact area with each other is small, so the sliding friction is small, and the slider 7 can slide smoothly.

As explained above, the daytent-type slide switch according to the present invention operates a part of the rotary operating body protruding outside the switch case to rotate the operating body in a daytent manner, and engages the operating body and the connecting body. In a detent changeover type slide switch that slides a combined slider, the operation body includes an operating section, a pivot section, a connecting arm section connected to the slider, and a connecting arm section extending around the outer periphery of the pivot section. An elastically deformable detent spring part is integrally molded with a synthetic resin material, the pivot part of the operating body is rotatably held in the case, and a variable positioning part is formed on the spring part of the operating body. Since the case is provided with a fixed positioning part that positions and locks the positioning part in correspondence with the part, the number of parts of the detent mechanism and the rotating operation body is reduced compared to the conventional slide switch. Assembling is easy and costs can be reduced, and since the detent spring part is also made of synthetic resin, there is little sliding noise during switching, allowing for soft switching with good feeling.
