Background
The term switch is interpreted as on and off. It also refers to an electronic component that can open a circuit, interrupt a current, or cause it to flow to other circuits. The most common switch is a human operated electromechanical device in which there are one or several electronic contacts. The "closed" of the contacts means that the electronic contacts are conductive, allowing current to flow; an "open" switch indicates that the electrical contact is not conducting to form an open circuit and no current is allowed to flow.
The existing switch mainly comprises a panel key 1', a mounting frame 2', a switch module 3' and a switch shell seat 4', wherein the panel key 1' is rotatably mounted on the mounting frame 2', the switch module 3' is mounted in the switch shell seat 4', the switch module 3' further comprises an inner key 31', a movable contact piece assembly and a static contact piece assembly, the inner key 31' is rotatably mounted in the shell seat 4', pressing arms 311' symmetrically extend from two sides of a rotating connecting part of the inner key 31', when the panel key 1' rotates towards one direction, the panel key 1' toggles the pressing arms 311' in the direction and drives the inner key 31' to rotate, and a swinging part arranged in the middle of the inner key 31' acts on the movable contact piece assembly and drives the movable contact piece assembly to be opened or closed with the static contact piece assembly. The switch described above has the following drawbacks: only through the cooperation operation of the panel key and the inner key end, when the pressing arm of the inner key extends longer, the swing amplitude of the long inner key is limited, especially the swing amplitude of the rotating connecting part near the middle of the inner key is minimum (namely, the rocker principle is that the swing amplitude of two ends of the rocker is large, the swing amplitude near the middle hinging position is small, and the longer the rocker is, the smaller the maximum limit swing angle is), in order to avoid the problem of pressing down the swing vacancy of the long inner key, the swing part of the long inner key is thickened, so that the movable contact assembly below the swing part position in the middle of the inner key can be touched and pressed down in the swing process, and the whole volume of the switch is thickened; the pressing arm mentioned in CN106373819a extends shorter, the toggle part on the back of the panel key approaches to the middle rotating connecting part, and the swing amplitude of the toggle part is smaller, so that the swing space of the two toggle parts is enlarged through upward tilting of the left and right sides of the panel key, and the whole volume of the switch is larger in any structure.
