[0014] In summary, the technical solution of the present invention has the following beneficial effects: The structural design of the present invention is reasonable. (1) By setting a quick-acting double-circuit switch, it includes: a housing with a receiving part; an operating part that accepts pressing operation; a first fixing member, a second fixing member, and a third fixing member arranged in parallel with a predetermined interval in the receiving part; a metal part having a contact part that is slidably connected to the second fixing member and the third fixing member; a quick-acting mechanism that drives the metal part when the operating part is pressed to a predetermined position; and a base provided at the bottom of the housing. Thus, when the operating part is pressed to a predetermined position, the quick-acting mechanism can drive the metal part to move accordingly, so that the contact part on the metal part slides accordingly with the second fixing member and the third fixing member. (2) By setting the quick-acting mechanism, it has: a first driving body, a metal part is set on the first driving body, one end of the first driving body is provided with a first fulcrum that forms a rotation fulcrum with the first fixed part, the middle part of the first driving body is provided with a contact part that is slidably connected to the second fixed part, the other end of the first driving body is provided with a contact part that is slidably connected to the third fixed part, and the other end of the first driving body is also provided with a first connecting end; a second driving body, the second driving body is located above the first driving body, one end of the second driving body is provided with a second connecting end, the middle part of the second driving body is provided with a second fulcrum that forms a rotation fulcrum with the second fixed part, and the other end of the second driving body is provided with a pressed part that is pressed by the operating component; a spring, the spring is located below the first driving body, one end of the spring is connected to the second connecting end, and the other end of the spring is connected to the first connecting end; thereby making the first driving body, the second driving body, and the spring of the quick-acting mechanism form a whole that can generate rapid switching and linkage, that is, the working principle is: when When the operating component is pressed down by an external force: First, the pressed part of the second driving body contacts the operating component, and the second driving body rotates clockwise around the second fulcrum. At this time, the pressed part of the second driving body swings downward, and the second connecting end of the second driving body pulls the spring to swing upward. The second connecting end gradually moves from the position below the first fulcrum to the height position of the first fulcrum, and the spring is gradually stretched. Then, when the second connecting end passes the height position of the first fulcrum, the spring is stretched to its maximum length. This position is the critical state transition point. Next, when the second connecting end continues to swing upward to the position above the first fulcrum, the spring pulls the first connecting end of the first driving body. Under the action of the spring tension, the first driving body rotates upward around the first fulcrum instantaneously to its position. Then, the second driving body swings to its position. At this time, because the first connecting end swings upward and moves closer to the second connecting end by a certain distance, the spring is gradually shortened by a small distance, and the upward change of the metal part is completed.When the operating component loses external force: the spring, due to its stretching, needs to reset. Therefore, under the action of the spring, the first driving body rotates downward around the first fulcrum to its designated position, completing the downward position change of the metal part. The second driving body rotates counterclockwise around the second fulcrum. At this time, the second connecting end of the second driving body is pulled downward by the spring and swings back to the position below the first fulcrum. The pressed part of the second driving body swings upward until the pressed part drives the operating component to reset upward. From the above analysis, it can be seen that when the operating component of the quick-acting double-circuit switch of the present invention is pressed to the designated position, the quick-acting mechanism can achieve a rapid response of the metal part, thereby ensuring the synchronicity of the switching between the circuits of the switch during the quick-acting mechanism's switching.

At this time, the pressed part of the second driving body swings downward, and the second connecting end of the second driving body pulls the spring to swing upward. The second connecting end gradually moves from the position below the first fulcrum to the height position of the first fulcrum, and the spring is gradually stretched. Then, when the second connecting end passes the height position of the first fulcrum, the spring is stretched to its maximum length. This position is the critical state transition point. Next, when the second connecting end continues to swing upward to the position above the first fulcrum, the spring pulls the first connecting end of the first driving body. Under the action of the spring tension, the first driving body rotates upward around the first fulcrum instantaneously to its position. Then, the second driving body swings to its position.

Function: The installation of the silencing plugs 9 and silencing pad 10 means that when the first driving body 5 contacts the silencing plugs or silencing pads 10, the first driving body 5 stops switching, which can reduce operating noise and achieve upper and lower limits, improving the user experience. When the silencing structure (i.e., silencing plugs 9 and silencing pads 10) is present, the switch is a silent switch, which can effectively reduce switching noise. When the silencing structure is removed, the structure hits the housing and base, making a crisp sound, which is then a audible switch. Therefore, it is possible to switch between silent and non-silent switches. The cooperation between the sealing ring 8 and the operating component 2 can improve waterproof performance. Preferably, the two silencers 9 are installed in the through holes on the two housings, the operating component 2 is an L-shaped button, and the housing 1 can be a rubber shell.
