8 and 9, the substrate 30 is installed on the inner bottom of the switch body 20. The moving magnet portion 42 of the generator 40 is lifted high at its tip end when it is not pressed, because it is designed to face upward in a state where no external force is applied to the arm 422. Here, in the embodiments shown in Figs. 8 and 9, the second bias spring 27 is shown in a state that is elastically lifted upward by a second bias spring 27 supporting the provided extension piece 40c, but the second bias spring 27 Even when) does not exist, the arm 422 assumes the same posture.

On the extension piece 40c, a pressing portion 70c in the middle of the operation plate 70 is placed. In this state, when an external force is applied to the operation plate 70 by the seesaw-shaped button 10 from above, the operation plate 70 rotates vertically downward by a predetermined angle based on the rotation shafts 70a and 70b at both ends thereof. do. At this time, by the rotation of the operating plate 70, the pressing portion 70c of the operating plate 70 lowers the extension piece 40c, and the elastic deformation portion 422a of the arm 422 is elastically deformed. In addition, when the second bias spring 27 is installed and located under the extension piece 40c, the second bias spring 27 is also elastically deformed.

In addition, when the external force is removed, the extension piece 40c and the operation plate 70 return to their original positions by elastic restoring force such as the elastic deformation portion 422a and the bias spring 27. In this process, a current is generated in the fixed coil part 41 due to a change in the magnetic field by the moving magnet part 42. The generated current is used to drive the circuit unit 60.

It works as a point. Accordingly, the switch 50b located at the lower right of the seesaw type button 10 is pressed to be in an ON state. At the same time, the middle portion of the lever hung button 10 presses the pressing portion 70c of the operation plate 70, and thus an extension piece 40c extending from the moving magnet portion 42 of the generator 40 ) Goes down. As the moving magnet part 42 moves in this way, power generation from the generator 40 occurs. The power generation from the generator 40 occurs for a short time even by one movement of the moving magnet part 42 in one direction, and the electric current generated therein is transmitted to the circuit part so that the circuit part 60 operates. The circuit unit 60 may include a storage component such as a storage battery or a capacitor capable of accumulating the current, and the storage component supplies the circuit unit 60 with a current required for operation for a given time. The circuit unit 60 starts operation by supplying current, detects the switch 50b pressed by the seesaw type button 10, generates a corresponding switching signal, and wirelessly switches the switch 50b.

Referring to Fig. 12, when the other side (left in the drawing) of the seesaw type button 10 is pressed, the protruding locking protrusion 12a on the opposite right side is caught in the locking groove 22b provided in the switch body 20, and the hinge point As a result, the switch 50a located at the lower left of the seesaw type button 10 is pressed to be in an ON state. At the same time, the middle portion of the lever hung button 10 presses the pressing portion 70c of the operation plate 70, and thus an extension piece 40c extending from the moving magnet portion 42 of the generator 40 ) Goes down (in the direction of the substrate). As the moving magnet part 42 moves in this way, power generation from the generator 40 occurs, thereby causing the circuit part 60 to operate. The circuit unit 60 starts operation by supplying current, detects the switch 50a pressed by the seesaw type button 10, generates a corresponding switching signal, and wirelessly generates a switching signal of the switch 50a.
