Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a seesaw switch.

[0002]

2. Description of the Related Art As shown in FIGS.
The lighting switch 7 used indoors is a see-saw switch (SEE-SAW SWITCH). The end of a see-saw-shaped key button 71 is pressed, the elasticity of a pressure spring 73 is received, and the push-down cylinder 72 at the bottom pushes the see-saw. When the conductive piece 74 is pushed in, the closing operation OFF or the energized state ON is adjusted.

However, the conventional seesaw switch has the following disadvantages. 1. The seesaw-shaped conductive piece 74 is seesaw-moved around the concave groove 751 on the upper part of the wiring piece 75 in the middle part as a pivot point.
The key button 71 has an installation space in the middle portion where the press-down cylinder 72 and the pressure spring 73 are installed. Therefore, the number of parts increases, and the time and cost for assembly increase.

[0004] 2. When the upper part of the U-shaped groove 751 is operated for a long time, the conductive piece 74 easily falls off due to wear or loosening. Also, when the push-down cylinder 72 is reciprocated over the conductive piece for a long period of time, the pressure spring 73 tends to generate elastic fatigue, the push-down force of the push-down cylinder 72 is reduced, and the effectiveness of the current-carrying connection is adversely affected. .

[0005] 3. The push-down cylinder 72 is installed in the middle of the switch body, and the lamp 76 is installed in the installation space 71.
The key button 71 is installed on the upper part of the camera 1 and is operated in conjunction with the key button 71. Since the conductive spring wire 78 is connected to the lamp 76 from above the third connection piece 77 that is the power source of the lamp 76, assembly is inconvenient and the failure rate increases.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a seesaw switch which can be easily assembled and can reduce the cost.

[0007]

According to a seesaw switch of the present invention, the following structure is included. The switch body is a hollow box body having a pivot hole. The minimally projecting circular member formed on the key button is inserted into the pivot hole. The key buttons are installed at the upper end of the switch body, and elastic hooks are formed on both left and right sides. The first wiring piece and the third wiring piece are respectively connected to ends of the power supply line. A first curved body is formed above the first wiring piece, and a first platinum contact point is fixed to the first curved body. A second curved body is formed above the second wiring piece, and a second platinum contact point corresponding to the first platinum contact point is fixed to the second curved body. The third wiring piece is connected to the resistor by a conductive wire. The lamp is fixed below the key button, and two conductive wires are connected to the resistor and the second wiring piece, respectively. Therefore, a seesaw switch that is formed with a small number of components and that can reduce the cost is formed. Also, the assembly is convenient, and the productivity is improved.

As shown in FIGS. 1 to 3, a seesaw switch according to an embodiment of the present invention has the following structure. The switch body 1 is a single hollow box body, and a pivot hole 11 is formed in the front and rear portions. The pivot hole 11 has the minimally projecting circular member 21 of the key button 2 inserted therein. Key button 2 is switch body 1
And elastic hook hooks 12 are formed on both left and right sides.

The first wiring piece 3 and the third wiring piece 5 are connected to the ends of the electric wires, respectively. A curved body 32 is formed above the first wiring piece 3, and a first platinum contact point 31 is fixed to the curved body 32. A curved body 42 is formed above the second wiring piece 4, and a second platinum contact point 41 corresponding to the first platinum contact point 31 of the first wiring piece 3 is fixed to the curved body 42. The third wiring piece 5 is connected to a resistor 52 by a conductive line 51.

The lamp 6 is installed below the key button 2 and is fixed by a plurality of fixing columns inside the switch body 1. The conductive lines 61 and 62 provided on the lamp 6 are connected to the resistor 52 and the second wiring piece 4, respectively. When the first wiring piece 3 and the second wiring piece 4 are connected and energized, the lamp 6 indicating the energized state emits light.

The switch body 1 has a U-shaped narrow groove 13 formed on the side surface corresponding to the key button 2, and one side is fixed to the side wall of the switch body 1 inside the U-shaped narrow groove 13. An elastic piece 14 is formed, and an arch-shaped projection 141 is formed on an inner surface of the elastic piece 14. Key button 2
At the bottom of both ends of the elastic piece 14, the arch-shaped projection 14
A projection 22 corresponding to 1 is formed.

One of the elastic pieces 14 is fixed, and U-shaped narrow grooves 13 are formed on both left and right sides. The protrusion 22 of the key button is formed corresponding to the elastic piece 14, and when two elastic pieces 14 are formed, two protrusions are formed. Key button is ON or OF by one elastic piece 14
Adjusted to F. When two elastic pieces 14 are used,
The texture of the pressing is improved and the service life is extended.

As shown in FIG. 3, the switch is adjusted to an off-off state. The left side of the key button 2 is flipped up about the pivot point of the minimally projecting circular member 21 in the middle part, and is not in contact with the curved body 42 and the second platinum contact point 41 on the second wiring piece 4. Therefore, the first wiring piece 3 and the second wiring piece 4 are not connected. Key button 2
The projection 22 has one elastic piece 14 and the arch-shaped projection 14
When 1 is connected and the right side is not pressed, the off-OFF state is maintained.

As shown in FIG. 4, when the left side of the key button 2 is pressed, the projection 22 slides down and the elastic piece 1
4 is pressed, the elastic piece 14 is pushed out, and the arch-shaped protrusion 141 passes through the protrusion 22,
Be dropped. As shown in FIG. 5, the elastic piece 14 is recovered by elasticity. At this time, the key button 2 is flipped up in the right direction, the lower left projection 22 pushes down the second platinum contact point 41 and the curved body 42 of the second wiring piece 4, and the second platinum contact point 41 1 A contact current is applied to the platinum contact point 31,
The first wiring piece 3 and the second wiring piece 4 are contact-energized, and the lamp 6 indicating the energized state emits light.

The projection 22 on the left side of the key button 2 is arranged on the bottom surface of the arched projection 141 of the elastic piece 14 on the left side, and the key button 2 is fixed by hooks. Elastic piece 14
Is installed only on the right side, the protrusion 2 on the right side
2 is fixed by an arch-shaped groove on the upper part of the right arch-shaped projection 141. When key button 2 cannot be switched, the second
The contact point 41 made of platinum and the contact point 31 made of first platinum are kept at an angle, are continuously pushed, and the energized state is maintained. When the elastic piece 14 is installed on one of the left side and the right side of the switch body 1, the key button 2 is fixed by a hook and ON or OFF is adjusted. When the two elastic pieces 14 are installed, the texture of pressing and the service life are greatly improved.

The present embodiment does not require the press-down cylinder 72, the pressure spring 73, the conductive spring wire 78, etc., which are installed in the conventional seesaw switch, so that the cost is reduced. Also, assembly is convenient and productivity is improved. Furthermore, since the pressure spring 73 that generates a current-carrying contact failure due to elastic fatigue is not provided,
Failure rates are reduced and service life is extended.

The push-down cylinder 72 is the switch body 1
Since the switch body is not installed in the switch, a space is omitted, and as shown in FIG.
