Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relatively small switch used for opening and closing various electric circuits.

[0002]

2. Description of the Related Art The conventional general switch described above is one in which one movable contact piece is pressed against the other fixed contact piece side to bring it into contact, or one of the contact pieces which is always in contact with is in a specific direction. It is often used to open and close by pressing.

[0003]

However, since the operation direction of the conventional switch is limited to a specific direction, it has a problem that its range of use is narrow and the mounting place is restricted.

It is an object of the present invention to provide a highly versatile switch that can be electrically opened and closed by pressing it in either the left-right direction or the up-down direction.

[0005] switch according to the present invention for achieving the above object, as well as to place the conductive cover to the inside surface of the base made of insulating material spaced apart to oppose to, among pre SL body

It consists of a vertically movable and tiltable pusher and a conductive material.
A coil spring provided with a contact portion at the tip of a linear portion extending from both ends is arranged, and the coil spring projects from the main body.
And a tip of the coil spring.
The end urges the pusher in a predetermined direction, and the contact portion is always
Is separated from the conductive plate, and the contact is made by the pressing element.
When the contact portion is pressed, the contact portion is made into the conductive cover.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail based on the illustrated embodiments. The drawings show an embodiment of a switch according to the present invention,
FIG. 1 is a front view with a conductive cover removed, FIG. 2 is an overall perspective view of the appearance, and FIG. 3 shows an example of the shape of a presser.

This switch comprises a box-shaped main body 2 made of an insulating material in which a conductive plate 1 serving as one contact piece is inserted into one surface and the other surface being open, and a conductive cover 3 covering the open surface of the main body 2. The coil spring 4 made of a conductive material is interposed between the main body 2 and the conductive cover 3, and the pressing element 5 made of an insulating material.

On the inner surface side of the main body 2, a shaft portion 2a for fitting the central portion of the coil spring 4 is projected, and a window portion 2b for exposing the exposed portion 1a of the conductive plate 1 is provided. ing. Further, an opening 2c is provided above the main body 2 so that the pusher 5 projects outward. The conductive plate 1 inserted into the main body 2 is provided with an appropriate number of connecting terminals 1b extended in an arbitrary direction and is drawn out of the main body 2.

The conductive cover 3 has a main body 2 as shown in FIG.
In combination with the switch, an outer cover for covering the switch is formed, and on the other hand, the conductive plate 1 inserted into the main body 2 is used.
Also serves as one contact piece electrically connected via the coil spring 4, and is always combined with the conductive plate 1 in an electrically insulated state.

At both ends of the coil spring 4 fitted in the central portion of the shaft portion 2a of the main body 2, the bent contact portions 4 are provided.
a, 4b are formed, and these contact portions 4a, 4b are formed.
Is always in contact with the conductive cover 3, and is formed so as to be able to contact the conductive plate 1 when it enters the area of the exposed portion 1a of the conductive plate 1. That is, the coil spring 4 is the pusher 5
Has a role as a spring that pushes upward to return it to the original position, and a role of a short bar that electrically connects the conductive plate 1 and the conductive cover 3.

As shown in FIG. 3, the pusher 5 has a substantially mountain shape having a top portion 5a in the center, and has shaft portions 5b at both ends thereof for pressing the left and right end portions of the coil spring 4, respectively. The shaft portion 5b also has a role of engaging with a recess formed in the main body 2 to prevent the pusher 5 from coming out.

In the state where the body 2 and the conductive cover 3 are combined, the pressing element 5 is pushed out to the outside by the coil spring 4 from the opening 2c provided in the body 2, but a fulcrum that restricts the movement. Therefore, when it is pressed from the outside in the up-down direction or the left-right direction, it can freely move up and down and tilt in the internal space formed by the main body 2 and the conductive cover 3. That is, the pusher 5 can move freely in the left-right direction and the up-down direction except that it is locked so as not to escape from the opening 2c.

FIG. 1 shows a free state in which an external force is not applied to the pressing element 5. In this state, the contact portions 4a and 4b of the coil spring 4 are in contact with the conductive cover 3, but the conductive plate 1 Since it does not enter the area of the exposed portion 1a of
The conductive plate 1 and the conductive cover 3 are in a switch-off state in which they are not electrically connected. In this state, the protrusion height of the pusher 5 is maximum and the top portion 5a is at the level of the free position a. If the pusher 5 is pushed slightly to the left as shown in FIG. 4 from this state, one contact portion 4a of the coil spring 4 approaches the exposed portion 1a of the conductive plate 1, but the top 5a of the pusher 5 is switched off. Since the contact portion 4a has not yet entered the region of the exposed portion 1a of the conductive plate 1 until reaching the guarantee limit position b, the conductive plate 1 and the conductive cover 3 remain non-conductive.

When the pressing element 5 is further pressed in the same direction from this state, one contact portion 4a is brought into contact with the conductive plate 1 as shown in FIG.
The conductive plate 1 and the conductive cover 3 are electrically connected to each other through the coil spring 4 because they come into contact with the exposed portion 1a.

In this state, the top 5a of the pusher 5 is in the switch-on guaranteed limit position c. That is, in FIG. 4 and FIG. 5, the position of the top portion 5a of the pressing element 5 is the operation region S from switch-off to switch-on from the switch-off guarantee limit position b to the switch-on guarantee limit position c.

Further, the pusher 5 is pushed down in the same direction,
As shown in FIG. 6, the state of being pushed into the main body 2 is the maximum operation limit for switching on. Of course, when the pressing element 5 is released, the coil spring 4 and the pressing element 5 are returned to the original position shown in FIG. 1 by the elastic force of the coil spring 4 and are switched off.

The above is the case where the pressing element 5 is pressed to the left side, but when it is pressed to the right side in the opposite direction, the contact portion 4b on the other side of the coil spring 4 electrically connects the conductive plate 1 and the conductive cover 3 to each other. Connect to each other. FIG. 7 shows the operation limit position of the pusher 5 when the pusher 5 is pressed in the opposite direction.

In the above, the pressing element 5 is pressed in the left-right direction. However, if the pressing element 5 is pressed in the direct downward direction as shown in FIG. 8, both contact portions 4a, 4b of the coil spring 4 are both conductive plates 1.
The conductive plate 1 and the conductive cover 3 are electrically connected to each other by contacting the exposed portion 1a.

As described above, it is possible to electrically open and close the pressing element 5 regardless of whether the pressing element 5 is pressed in the left-right direction or in the vertical direction. The pressing element 5 is not limited to the shape shown in the embodiment, as long as it can be pressed from the outside in the left-right direction or the up-down direction. Good.

[0021]

As described above, the switch according to the present invention can be operated by turning the pusher up and down or tilting to turn it on and off, so that it is highly versatile and has less restrictions on the mounting location. .
