Description

Rotary connecting push switch

The present invention relates to a push switch, and more particularly, by operating a push button in a direction perpendicular to the connection direction of a movable side connection part and a fixed side connection part, the connection and opening of the terminal are made to improve the switch operation feeling and overall It is possible to design various switching functions by circumferentially forming the switch connection pattern part which connects and opens at least one fixed side connection part to the movable side connection part which rotates by manipulation of a push button. The present invention relates to a rotary connection push switch which is composed of metal components to further extend the life of the product.

Conventionally, a push switch used in a mobile phone, a game machine, various audio devices, or the like includes a housing formed of an insulating resin, a movable side connection part and a fixed side connection part installed in the housing, and a plurality of push connection parts connected to the movable side connection part and the fixed side connection part. And a push button protruding from the housing and operating the movable side connecting portion, wherein the movable side connecting portion selectively connects and opens to the fixed side connecting portion in response to the push button being pressed. It is supposed to perform

However, since most of the push switches are configured in the same direction as the push button operation direction with respect to the connection direction of the fixed side connection part and the movable side connection part, the push switch becomes larger in the horizontal direction and the vertical direction size. There has been a problem that the size of the electronics mounted with the switch also increases.

In recent years, in accordance with the trend of miniaturization of mobile phones, game consoles, portable audio devices, and the like, there is an increasing demand for miniaturization of the mounting area of mounting products such as push switches used therein, and various methods have been devised for this purpose. For example, Korean Patent Registration No. 10-755223 discloses a configuration in which the push button is operated in a direction perpendicular to the connection direction of the movable side connection portion and the fixed side connection portion, and this configuration changes the longitudinal size of the push switch.

Since the structure is pressurized to the contact portion 120, the vertical size of the push switch is increased by the thickness of the pressing portion 111, there was a limit to miniaturization of the product, furthermore, the operation direction of the push button 110 Since the pressing of the movable contact portion 130 by the pressing portion 111 acts in a right angle with respect to the pressing direction of the movable contact portion 130 and the operation direction of the push button 110 as before. It requires a larger pressing force than it has a disadvantage that the operation feeling is reduced.

In addition, in the conventional push switch, the pressing portion 111 of the push button 110 is a synthetic resin, and the movable contact portion 130 is made of metal, and if used for a long time, the material is weaker than the movable contact portion 130. Since the pressing part 111 is worn and the pressing function is lowered, it causes a connection failure at the connection part and at the same time, shortens the lifespan. As shown in FIG. 7, one of the movable contact part 130 and one Since the switching operation is performed by the connection and opening of the central fixed contact portion 120, only a simple on / off function can be performed, and thus, it is difficult to change the design to have various switch functions.

By repeatedly operating the push button 50 as shown in FIGS. 5A and 5B, the rotating body 20 rotates intermittently by a predetermined angle so that the variable connecting portion 41 of the second terminal 40 switches. Since the switching to the position of the connection pattern 22 or the open pattern 23 of the pattern portion 21, the switch function for turning on or off between the first terminal 30 and the second terminal 40 is repeatedly performed.

Meanwhile, the present invention further includes another third terminal together with the second terminal 40, and changes the connection pattern 22 and the opening pattern 23 of the switch connection pattern portion 21 of the rotating body 20. By doing so, various switch functions can be performed.

For example, as shown in FIG. 6, the open pattern of the switch connection pattern part 21 is changed into the first open pattern 23a and the second open pattern 23b, and the variable connection part of the second terminal 40 is provided. The 41 is positioned in the first opening pattern 23a, the variable connecting portion 41A of the third terminal 40A is positioned in the second opening pattern 23b, and then the push button 50 is operated to rotate the rotating body. When the intermittent rotation is made in the direction of the arrow, in the initial state, both the second terminal 40 and the third terminal 40A become " off " which opens with the first terminal 30.

In this state, when the pushbutton is operated once, the variable connecting portion 41 of the second terminal 40 is positioned in the second opening pattern 23b, and the variable connecting portion 41A of the third terminal 40A is connected to the connecting pattern ( 22a), it is in the " third terminal on " state where the third terminal 40A and the first terminal 30 are connected.

Subsequently, when the pushbutton is operated twice, the variable connecting portion 41 of the second terminal 40 is positioned in the connecting pattern 22a, and the variable connecting portion 41A of the third terminal 40A is positioned in the opening pattern 23a. Therefore, the second terminal 40 and the first terminal 30 are connected to the "second terminal on" state, and when the pushbutton is operated three times, the variable connecting portion 41 of the second terminal 40 is first opened. Since the variable connecting portion 41A of the third terminal 40A is positioned in the pattern 23a and is positioned in the second opening pattern 23b, the second terminal 40 and the third terminal 40A are again the first terminal ( 30) to the "off" state which is opened.

Therefore, the switch function is repeated, as shown in the following table, and various switch functions can be set by changing the number of terminals and the pattern of the switch connection pattern portion 21 in a similar manner.
