[0042] The use principle of the utility model is now described as follows:

[0043] Example 1

[0044] When the base 1 is inserted with four static spring assemblies 2, downward pressure is applied to the button 39, the movable seat 3 sinks, the first elastic member 5 is compressed and stored, the pull rod 14 moves from the slide groove 37 to the top of the locking groove 36, the moving point 82 abuts the static point 22, and a collision impact force is generated, so that the moving spring piece 81 moves upward, and then the second elastic member 9 is compressed and stored. The force applied to the button 39 is released, the first elastic member 5 releases the elastic force, and pushes the movable seat 3 to rise until the pull rod 14 abuts the locking groove 36, preventing the movable seat 3 from continuing to rise and move. The second elastic member 9 releases the reaction force, so that the moving point 82 is tightly abutted against the static point 22, so that the first static spring legs 21 of the pairs are turned on, and the current is transmitted to the port of the LED lamp circuit board 4 through the first static spring leg 21, the static point 22, the moving point 82, the moving spring piece 81, and the second elastic member 9, so that the patch LED lamp of the LED lamp circuit board 4 lights up, and the button switch is in a closed state;

[0045] When downward pressure is applied to the button 39 again, the movable seat 3 sinks, the movable spring 81 moves upward, the first elastic member 5 and the second elastic member 9 are compressed to store energy, the pull rod 14 leaves the locking groove 36, and moves to the slide groove 37 on the other side of the locking groove 36, and the pressure applied to the button 39 is released. The first elastic member 5 releases the reaction force to push the movable seat 3 to rise and reset, and the second elastic member 9 releases the reaction force to push the movable spring 81 to abut against the support frame 31. At this point, the power of the two ports of the LED lamp circuit board 4 is interrupted, and the button switch is in the off state.

[0046] Example 2

[0047] When two static spring assemblies 2 and a second static spring foot 7 are inserted into the base 1, the second static spring foot 7 is connected to the power port, and the electric energy is transmitted from the second static spring foot 7 and the second elastic member 9 to the port of the LED lamp circuit board 4. When downward pressure is applied to the button 39, the movable seat 3 sinks, causing the first elastic member 5 to compress and store energy, and the pull rod 14 moves from the slide groove 37 to the top of the locking groove 36. The moving point 82 abuts against the static point 22, generating a collision impact force, causing the moving spring piece 81 to move upward, thereby compressing the second elastic member 9 to store energy, releasing the force applied to the button 39, and the first elastic member 5 to release energy. Component 5 releases the elastic force, pushing the movable seat 3 up until the pull rod 14 abuts the locking groove 36, preventing the movable seat 3 from continuing to rise, and the second elastic component 9 releases the reaction force, so that the moving point 82 tightly abuts the static point 22, so that the first static spring foot 21 is conductive, and the electric energy is transmitted to the port of the LED lamp circuit board 4 through the first static spring foot 21, the static point 22, the moving point 82, the moving spring piece 81, and the second elastic component 9. Since there is electric energy at the other port of the LED lamp circuit board 4, at this time, the SMD LED lamp of the LED lamp circuit board 4 lights up, and the button switch is in a closed state.
