Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the utility model is not limited thereto.

As shown in Figure 1, Figure 2 and Figure 3:

Ball micro switch, including button 1, upper cover 2, base 3, terminal 4, button 1 is set in the upper cover 2, upper cover 2 is flipped and buckled on the base 3, and terminal 4 is inserted on the base 3; it also includes The ball 5 is arranged at the bottom of the button 1, and the button 1 can be pressed to make the ball 5 electrically contact with the terminal 4 or disconnect the circuit.

The terminal 4 includes a conduction portion 41 and a pin 42 , the conduction portion 41 is disposed on the top of the base 3 , and the pin 42 protrudes from the bottom of the base 3 . The two terminals 4 are arranged in parallel and are not connected to each other. The distance between the conductive parts 41 matches the diameter of the ball 5 .
