[0015] The technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application.

[0016] Specific embodiment 1: please refer to Figures 1 to 6 In the embodiments of the present application, the pressing plate for the self-power generation switch is in the form of a sheet, has certain toughness to avoid breaking, for example, a metal sheet, and can also be made of plastic material, and is selected according to actual production, the pressing plate in the present application comprises a first pressing arm 801, a second pressing arm 802 and a third pressing arm 803, the first pressing arm 801, the second pressing arm 802 and the third pressing arm 803 are sequentially connected to form a U-shaped structure, the first pressing arm 801 and the third pressing arm 803 are the same in structure, in actual installation, the pressing plate is rotatably installed with the bottom shell 1, the second pressing arm 802 extends in the direction of the U-shaped opening in the middle and has a lower pressing piece 802-1, the lower pressing piece 802-1 is above the micro switch 901, and a compression spring 10 is pressed between the bottom of the second pressing arm 802 and the bottom shell 1, that is, the second pressing arm 802 on the pressing plate 8 is a raised portion.

[0017] The first pressing arm 801 and the third pressing arm 803 are further provided with an upper pressing piece 804, the upper pressing piece 804 is transverse to the first pressing arm 801 and the third pressing arm 803 and above the lower pressing piece 802-1, the spacing between the upper pressing piece 804 and the second pressing arm 802 forms a movable hole 805, the lower pressing piece 802-1 is in the movable hole 805, and the metal tab 601 of the power generation module 6 is arranged between the upper pressing piece 804 and the lower pressing piece 802-1.

[0018] The first pressing arm 801 is provided with two limiting rods away from the second pressing arm 802, which are a first limiting rod 801-1 and a second limiting rod 801-2, the first limiting rod 801-1 and the second limiting rod 801-2 are installed on the left and right sides of the first pressing arm 801 and the positioning assembly 5 in the bottom shell 1; the positioning assembly 5 includes a first clamping seat 501 and a first clamping hook 502, the first clamping seat 501 and the first clamping hook 502 are fixed in the bottom shell 1 respectively, the first clamping seat 501 is provided with a concave clamping groove 501-1 for placing the first limiting rod 801-1, the second limiting rod 801-2 is inserted into the first clamping hook 502, and the first pressing arm 801 can rotate around the first limiting rod 801-1 through the limiting action of the first clamping hook 502 and the supporting action of the first clamping seat 501, so that the pressing plate 8 rotates around the first limiting rod 801-1, achieving the effect of rotating the pressing plate 8 relative to the bottom shell 1, the first limiting rod 801-1 rotates in the clamping groove 501-1, thereby effectively avoiding the first limiting rod 801-1 from falling off the first clamping seat 501 during rotation by using the limiting structure of the clamping groove 501-1, the structure of the second pressing arm 802 and the first pressing arm 801 and the installation structure and principle of the bottom shell 1 are the same, and are not repeated.
