Description
Technical Field
[0001] The utility model relates to the technical field of switches, in particular to a rocker switch. Background Art
[0002] A rocker switch is a device used to turn current on and off in a circuit. When the user presses the button of the rocker switch, the button applies a flipping force to the rocker through a transition piece, causing the rocker to rotate, thereby achieving contact or separation between the contacts to achieve the purpose of turning current on and off.
[0003] The existing rocker switch includes a base, a button, a moving contact assembly, and a static contact assembly. The button is hingedly set on the base and rotates relative to the base. The moving contact assembly is connected to the button. The static contact assembly is set on the base. The static contact assembly includes a conductive base and a static contact set on the conductive base. When the button is pressed, it deflects, thereby driving the moving contact assembly to connect with the static contact, or separate from the static contact, to realize the conduction or disconnection of the rocker switch.
[0004] The base of the rocker switch is equipped with a wire inlet, and the conductive base is equipped with a corresponding spring that compresses the wire. The wire is inserted from the wire inlet and enters the conductive base. The spring compresses the wire, thereby achieving quick wiring. If the wire needs to be released, a tool such as a flat-bladed screwdriver is inserted into the base to press the spring, causing it to deform and cancel the positioning of the wire, so that the wire can be pulled out. However, the above structure has the problem that if too much force is applied, the spring will exceed the elastic deformation range and produce plastic deformation, resulting in the spring no longer being able to clamp the wire, thus losing the quick wiring function. Summary of the Invention
[0005] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a rocker switch, in which a positioning piece is set on the conductive seat to limit the deformation range of the spring, so as to prevent the spring from exceeding the elastic deformation range and generating plastic deformation, thereby losing the function of quick wiring.
[0006] The technical solution of the present utility model is as follows: a rocker switch comprises a base, a button, a moving contact assembly, and a static contact assembly, wherein the moving contact assembly and the static contact assembly are arranged in the base, and the static contact assembly comprises a conductive seat and a static contact arranged on the conductive seat, the button is movably arranged on the base, and cooperates with the moving contact assembly to drive the moving contact assembly to swing, thereby realizing contact or separation with the static contact, an elastically deformable spring is provided on the conductive seat, a wire insertion port for wires to enter and exit, and an unlocking port located on one side of the wiring port are provided on the conductive seat, and a positioning member is further provided on the conductive seat, wherein the positioning member is arranged on the movement trajectory of the spring and is located on the side of the spring away from the wire insertion port.
[0007] The above technical solution is adopted, and a positioning piece is set on the conductive seat. When the wire needs to be removed, a tool is inserted from the unlocking port and pressed inwardly on the spring piece, causing the spring piece to deform and move toward the positioning piece.
