Description
Technical Field
[0001] The utility model relates to the technical field of key switches, in particular to a key switch which can be turned on at any position. Background Art
[0002] The word switch means to open and close. It also refers to an electronic component that can open a circuit, interrupt the current or make it flow to another circuit. The most common switch is an electromechanical device that can be operated by a person, which has one or more electronic contacts. The "closed" contact means that the electronic contact is conductive and allows current to flow; the "open" switch means that the electronic contact is not conductive and forms an open circuit, which does not allow current to flow.
[0003] The existing traditional switch mainly includes a panel button, a mounting frame, a switch module and a switch housing. The panel button is rotatably mounted on the mounting frame, the switch module is mounted in the switch housing, and the switch module further includes an inner button, a moving contact piece assembly and a stationary contact piece assembly. The inner button can be rotatably mounted in the housing, and the inner button has pressing arms symmetrically extending on both sides of its rotating connection portion. When the panel button rotates in one direction, the panel button moves the pressing arm in the direction and drives the inner button to rotate. The swinging portion provided in the middle of the inner button acts on the moving contact piece assembly and drives the moving contact piece assembly to disconnect or close with the stationary contact piece assembly. For example, in the related technical solutions in CN212783161U and CN213340175U, "the bracket is also provided with a rotating groove, a rotating shaft is provided on the side wall of the rotating groove, a rotating block is provided in the middle of the button, a shaft hole is provided in the rotating block, and the shaft hole is rotatably connected with the rotating shaft". The button of this structure is a "seesaw" design, which takes the middle as a fulcrum and can rise and fall at both ends. Due to the rotation trajectory of the key, each switch contact can only be set at the bottom of the two ends of the key, and the switch contact cannot be set in the middle of the key or at the bottom of the left and right sides. The distribution position of each switch contact is relatively limited and cannot be set arbitrarily. Summary of the invention
