Description

Self-generating switch Technical Field Embodiments of the present invention relate to a self-generating switch. Background In general, a wiring switch is widely used as an appliance for powering on or off electric devices such as lighting and home appliances in indoor wiring, mainly in a push button manner. Such a wiring switch may connect one button to a circuit and be installed at a wall or the like to control the on/off of one electric device, or may connect a plurality of buttons in parallel to one circuit and be installed to selectively control the on/off of a plurality of electric devices, respectively. However, in order to solve the inconvenience of embedding the push button in a wall, the cumbersome nature of replacing an internal battery, and the like, a self-generating switch that generates electricity for a switching operation by self-generating electricity without an external power source has been proposed. However, the conventional self-generating switch generates noise when the switch is pushed, and the push switch is not operated smoothly enough, resulting in excessive force required by the user to push the button. In addition, the existing self-generating switch needs to be composed of a large number of parts, is complex in shape, and increases manufacturing cost. Prior art literature Patent literature Patent document 1 korean patent laid-open No. 10-1987929 (2019.06.04). Disclosure of Invention Problems to be solved by the invention An object of an embodiment of the present invention is to provide a self-generating switch in which a user such as an elderly person or a weak person can press the switch with a small force even though the operation of a button is smooth when the switch is pressed. Further, an object of an embodiment of the present invention is to provide a self-generating switch which can be formed with a simple structure while simplifying the parts constituting the switch. Further, an object of an embodiment of the present invention is to provide a self-generating switch capable of easily increasing switching members for controlling a plurality of electrical devices. Means for solving the problems According to an embodiment of the present invention, there is provided a self-generating switch including a lower body, an upper body rotatably coupled to one side of the lower body through a rotation shaft, a Printed Circuit Board (PCB) coupled to the upper body and including a contact portion capable of contacting a switching member pressed by a user, and a generator disposed on a lower surface of the printed circuit board and supplying power to the printed circuit board, wherein the upper body rotates while applying pressure to a generator bar formed in the generator to generate power when the user presses the switching member. A pressing member is formed on the inner side of the lower body, and the pressing member can apply pressure to the power generation strip when the upper body rotates. The pressing member may have a shape protruding upward from the lower body. An elastic member may be provided between the power generation strip and the upper body. The elastic member may be a torsion (torsion) spring. The switch member may include a plurality of pressing positions, and the contact portion of the printed circuit board may be formed with the number corresponding to the plurality of pressing positions. The self-generating switch of the present invention may further include an upper cover covering the upper body and the printed circuit board. The upper cover is coupled to the upper body so as to rotate together with the upper body. The distance between the switch member and the rotation shaft may be longer than the distance between the generator bar and the rotation shaft. Effects of the invention The embodiment of the invention can provide a self-generating switch, when the self-generating switch is pressed, the rotation shaft formed on one side of the lower body is used as a reference, the operation feeling is smooth by utilizing the lever principle, and thus, a user can press the self-generating switch with small force. Further, the embodiment of the present invention can provide a self-generating switch in which a button and its accessory parts constituting the switch can be simplified by disposing a switch member, a printed circuit board, and a self-generating device on an upper body, and the self-generating switch can be formed with a simple structure. Further, embodiments of the present invention provide a self-generating switch capable of freely increasing a pressing position on a switching member by directly contacting the switching member with a printed circuit board.
