[0028] See also Figure 5 In this embodiment, the prompt component 6 includes a photoresistor lamp 601 and a wire 602; the photoresistor lamp 601 is fixedly connected to the inner wall of the mounting hole 107; the lower end of the photoresistor lamp 601 is fixedly connected to the wire 602; the lower end of the wire 602 is fixedly connected to the upper end of the Z-shaped spring piece 305.

[0029] When work is required, the first column 201 is rotated to make the outer wall of the second fixing block 202 fit with the upper end of the button 304, and the rotation is continued to make the second fixing block 202 press the button 304 downward, so that the U-shaped spring piece 302 is deformed;

[0030] When the U-shaped spring piece 302 is deformed, the Z-shaped spring piece 305 will move downward, so that the second conductive block 307 at the lower end of the Z-shaped spring piece 305 will fit with the third conductive block 402 on the second conductive sheet 401, so that the current information is transmitted from the first conductive sheet 301 to the second conductive sheet 401.

[0031] Then, when the second spring 303 is subjected to the pressure generated by the deformation of the U-shaped spring piece 302, it rebounds, causing the U-shaped spring piece 302 to move upward, thereby driving the Z-shaped spring piece 305 to move upward, and the upper end of the first conductive block 306 on the Z-shaped spring piece 305 fits with the lower end of the fourth conductive block 502, thereby transmitting the current information from the first conductive sheet 301 to the L-shaped conductive sheet 501. When the Z-shaped spring piece 305 moves upward, it drives the button 304 to move upward, thereby causing the first column 201 to rotate through the squeezing of the second fixed block 202 by the button 304. The above work can also be performed by pressing the first column 201 downward, but the lower end of the limit block 204 is farther away from the lower end of the inner wall of the second slot 103, so it is not easy to cause accidental touch.

[0032] Through the above steps, when the micro switch is installed, the rotating component 2 is rotated or pressed hard to make the rotating component 2 move the common terminal component 3 in the housing component 1 downward, so that the common terminal component 3 is in contact with the normally open terminal component 4, and the prompt component 6 emits a light to give a prompt, thereby solving the problem that the micro switch is too sensitive, which is easy to be accidentally touched, and there is no prompt when pressed, resulting in work errors.

[0033] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
