The present invention relates to a push button switch that is switched on and off by a push operation, and more specifically, a locking member, an operating member, and a fastening member, which are connected to the button unit and installed in the switch, are pressed to press any part of the button unit. Even if it is a push switch to the force of the button portion is transmitted in a balanced manner to the same feeling.

In general, a push button switch is installed in an electronic device such as a video, a TV, or an audio, and a button exposed to the outside of the panel is operated by a user, and a tact switch installed inside is operated by the button. As a result, a circuit installed in an internal printed circuit board is turned on and off to perform a predetermined operation.

The general push button switch includes a tact switch having a pressurized part and a button disposed to have a coaxial line with the pressurized part, and the button presses the pressurized part according to the pressing of the button to obtain a predetermined signal and electrical operation. It is called one. Such a push button switch may be commonly used in home appliances such as televisions, including a power switch of a computer. Hereinafter, among various electronic products, a power switch and a reset switch, which are commonly found in the vicinity, may be implemented. As an example, a general switch will be described.

As shown in Figure 1, the general switch is inserted into the vertical through-holes formed in the front portion of the casing 101, which is the main frame, the button 120 is held in the casing 101, the lifting is freely provided, and Is disposed on the coaxial line with the button 120 is interposed between the tact switch 150 and the button 120 and the tact switch 150 to apply power to the system in contact with the button 120 when the button 120 is pressed It includes a coil spring 140 to elastically restore the button 120 when the button 120 is released.

One side of the front portion of the casing 101 is recessed to a predetermined depth from the plate surface to be an insertion portion 103 into which the button 120 is inserted. In addition, the first insertion hole 105 and the transmission part 127 of the button 120, which are inserted and held by the locking portion 123 of the button 120, are inserted into the insertion portion 103, and are freely lifted and inserted. The through hole 107 is provided.

The button 120 is inserted into the pressing portion 121 exposed to the front surface of the casing 101 and the first through hole 105 formed in the casing 101 to release the button 120 out of the casing 101. The locking portion 123 and the second through hole 107 of the casing 101 to prevent the insertion of the tact switch 150 when the pressing portion 121 is formed integrally with the pressing portion 121. It includes a transmission unit 127 for pressing the pressing unit 151.

The locking portion 123 protrudes from the back toward the tact switch 150 along the central axis of the pressing portion 121 and includes a predetermined inclined surface 124 as shown in FIG. 1 to be inserted into the first through hole 105. At the end of the inclined surface 124, a locking step 125 is formed. The button 120 is held by the casing 101 by the locking step 125, thereby preventing the button 120 from being separated out of the casing 101.

The transmission part 127 protrudes and extends from the back toward the tact switch 150 along the central axis of the pressing part 121, and is inserted into the second through hole 107 formed in the casing 101 to be pressed by the user. When pressing the part 121, the pressing part 121 moves integrally to press the pressurized part 127 of the tact switch 150.

The tact switch 150 is provided on the PCB substrate 153 which is disposed on the front surface rear surface of the casing 101 with a predetermined space from the casing 101, and is pressurized to contact the transfer part 127. 151).

In addition, between the button 120 and the tact switch 150, one end is in contact with the back surface of the pressing portion 121, the other end is provided with a coil spring 140 is in contact with the plate surface of the insertion portion 103 of the button 120 It is compressed at the time of joining and elastically returns when the button 120 is depressurized to return the button 120 to its original position.

If the button switch having such a configuration has a large size, the button is not pressurized correctly, but only one side of the button is lowered and the tact switch is not pressurized correctly. When the switch is lowered and then raised, the friction force between the switch and the housing is stronger than the elastic force for restoring the initial state, such that the button switch is fixed in the lowered state.

The present invention is derived to solve the above-described problems, and provided with an operating member connected to the lower surface of the button portion, even if any portion of the pressurized portion of the button by the operating member evenly pushed the button to the button There is a technical problem in providing a button switch in which the portion is lowered or raised without tilting.
