[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] In one embodiment, see Figure 1 and Figure 2 , a universal self-locking micro switch with optimized structure, wherein the button 1 is provided with a buckle at the head, which can be installed and connected with various buttons 1 on the ceiling light, instrument center control and other assemblies, and a plug-in LED insertion hole is provided inside the button 1, which can meet the backlight and indication functions of the assembly. A self-locking motion track peach core is also provided on the left side of the button 1, and the self-locking and unlocking of the gear position is realized under the action of the lock hook 3 and the support spring 2; the support spring 2 is arranged in the spring hole at the lower end of the button 1, and is positioned at the bottom of the shell 7, providing elastic force for the up and down movement of the button 1 and the floating of the lock hook 3. The lock hook 3 is arranged on the left side of the button 1, and is positioned by the positioning groove at the bottom of the shell 7, and the self-locking and unlocking of the gear position in the motion track of the button 1 is realized under the elastic force of the support spring 2. The moving contact piece 4 is arranged on the left side of the button 1, and is connected to the button 1 in a floating manner through the compression spring of the moving contact piece 4, and is contacted and separated with the static contact piece when the button 1 moves up and down, so as to realize the opening and closing of the circuit. The compression spring of the moving contact piece 4 is arranged on the left side of the button 1, below the moving contact piece 4, to realize the floating connection of the moving contact piece 4. The housing 7 is arranged below the switch, and is a connector of the button 1, the support spring 2, the lock hook 3, and the static contact piece 6. It is provided with a positioning groove, a positioning column, a guide groove, a buckle hole and other structures to realize the buckle connection between the button 1 and the static contact piece 6, and the button 1 moves smoothly and stably in the guide groove of the housing 7. The static contact piece 6 is arranged on the right side of the button 1, and is fixedly connected with the housing 7 by buckle, providing the opening and closing of the switch circuit and connecting with the external function output through 3 PIN pins.
[0016] How it works
[0017] The button 1 moves downward, the support spring 2 is compressed downward, and the lock hook 3 moves in the track of the core part of the button 1. When the button 1 moves downward for a certain distance and is limited by the structure, the F force is cancelled, the button 1 rebounds under the elastic force of the support spring 2, and the lock hook 3 locks the step in the center of the core of the button 1 to achieve self-locking of the travel. At the same time, the moving contact piece 4 is driven by the button 1 and the contact piece compression spring 5 to achieve the on-off switching with the static contact piece component 6 to complete the circuit opening and closing switching. Apply force F to the button 1 again, the button 1 moves downward, and the lock hook 3 moves in the track of the core part of the button 1. When the button 1 moves downward for a certain distance and is limited by the structure, the F force is cancelled, the button 1 rebounds under the elastic force of the support spring 2, and the lock hook 3 slides out of the step in the center of the core of the button 1 to achieve travel unlocking. The plug-in LED is installed in the LED mounting hole in the button 1, and can provide backlight and indicator light source after power is turned on.
[0018] The utility model is applicable to a universal self-locking micro switch with optimized structure, which eliminates the lock hook 3 springs, is convenient for automatic assembly, improves production efficiency, and reduces production time and material costs.
