Technical Field

[0001] The utility model relates to the technical field of micro switches, more specifically to a simple micro switch. Background Art

[0002] A micro switch is a small, highly sensitive electrical switch that is mainly used to detect and control tiny mechanical movements or signals. They are widely used in various devices and systems, such as electronic equipment, household appliances, industrial control, medical equipment, etc. The working principle of a micro switch is usually based on a mechanical structure design. When an external force is applied to the switch, the internal metal spring will deform, thereby connecting or disconnecting the circuit. This design enables the micro switch to produce a fast electrical response under tiny mechanical movements. For example, the prior art publication number is CN207052503U, a simple pressure test micro switch device.

[0003] However, the above-mentioned prior art still has the following problems when in use: traditional micro switches usually have only one triggering mode and cannot be applied in multiple scenarios, and the sub-pins on the micro switch are fixed, which is not convenient for replacement. Only the entire micro switch can be replaced, and the cost of use is high. Based on this, the utility model provides a simple micro switch with two triggering modes at the same time.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model

[0024] Referring to the attached drawings of the specification Figures 1-7 , the present utility model provides a simple microswitch, including an upper shell 1 and a lower shell 2 clamped together. A pressing button 3 is slidably arranged inside the upper shell 1. A round hole 4 is opened at the top end of the upper shell 1. The top end of the pressing button 3 penetrates through the round hole 4 and extends to the outside of the upper shell 1. A first spring 5 is fixedly arranged at the bottom of the pressing button 3. A conductive ball 6 is fixedly arranged at the bottom end of the first spring 5

[0025] Two first pins 7 distributed front and back penetrate through one side of the lower shell 2. Two second pins 8 distributed front and back penetrate through the other side of the lower shell 2. Two mounting holes 9 distributed front and back are opened on both sides of the bottom end of the lower shell 2. The two first pins 7 and the two second pins 8 respectively penetrate through a plurality of mounting holes 9. A guiding block 10 is fixedly arranged at the top of the lower shell 2. The top of the guiding block 10 contacts the bottom of the conductive ball 6

[0026] Moreover, the cross-section of the guiding block 10 is triangular, and the two sub-feet one 7 and the two sub-feet two 8 are distributed on the front and back sides of the guiding block 10. The guiding block 10 can be used to guide the movement of the conductive ball 6. A positioning plate 12 is fixedly arranged at the bottom of the upper shell 1, and the outer wall of the conductive ball 6 is in contact with the positioning plate 12. A positioning groove 13 adapted to the positioning plate 12 is opened at the top of the guiding block 10. When the pressing button 3 is pushed downward, the positioning plate 12 is inserted into the positioning groove 13, thereby improving the stability of the pressing button 3 during movement.

[0027] When in use, this simple microswitch has two triggering methods:

[0028] The first triggering method is: when the pressing button 3 is pushed downward, the conductive ball 6 at the bottom of the first spring 5 moves to the left and contacts the two sub-feet one 7 on the left side of the lower shell 2, so that the two sub-feet one 7 are connected to play a triggering role, as Figure 2 shown;

[0029] The second triggering method is: when the pressing button 3 is not pushed downward, the pressing button 3 generates an upward force under the elastic force of the first spring 5. At this time, the conductive ball 6 stops on the right side of the top of the lower shell 2, and the conductive ball 6 contacts the two sub-feet two 8 on the right side of the lower shell 2, so that the two sub-feet two 8 are connected to play a triggering role, as Figure 3 shown;

[0030] The whole simple microswitch has a small appearance, stable contact, a load life equivalent to the mechanical life of the first spring 5 itself, has a better cost advantage, and the operating force can be adjusted without replacing parts or adjusting the structure, realizing multi-scenario applications.

[0031] Referring to the attached Figures 1-7 to the specification, a rubber sealing ring 11 is provided between the pressing button 3 and the round hole 4. The rubber sealing ring 11 is sleeved outside the pressing button 3. The rubber sealing ring 11 can be used to improve the sealing performance between the pressing button 3 and the round hole 4;

[0032] Two sleeves 14 are fixedly embedded on the outer walls of the front and back sides of the lower shell 2. An insertion block 15 penetrates through one end of each sleeve 14. Slots 16 are opened on the outer walls of the two sub-feet one 7 and the two sub-feet two 8 away from each other. The insertion block 15 is inserted into the slot 16, which is convenient for the staff to install and disassemble the sub-feet one 7 and the sub-feet two 8;

[0033] Moreover, a second spring 17 is fixedly arranged at one end of each insertion block 15 away from the slot 16. One end of the second spring 17 is fixed to the inner wall of the sleeve 14. The elastic force of the second spring 17 is used to push the insertion block 15 to be inserted into the slot 16, thereby improving the stability of the sub-feet one 7 and the sub-feet two 8;

[0034] Moreover, a pull rod 18 penetrates through each of the second springs 17. One end of the pull rod 18 is fixed to one end of the insertion block 15. The other end of the pull rod 18 sequentially penetrates through the sleeve 14 and the outer wall of the lower shell 2. By grasping the pull rod 18, the position of the insertion block 15 can be conveniently adjusted.

[0035] By pulling the pull rod 18 to drive the insertion block 15 to move out of the slot 16, the first sub-foot 7 and the second sub-foot 8 can be pulled out of the mounting hole 9, so as to facilitate the staff to quickly replace the first sub-foot 7 and the second sub-foot 8. This can reduce costs and avoid the wear of the first sub-foot 7 and the second sub-foot 8 caused by frequent contact with the conductive beads 6, which affects the electrical connection of the circuit. When reinstalling the first sub-foot 7 and the second sub-foot 8, only need to align the first sub-foot 7 and the second sub-foot 8 and insert them into the mounting hole 9, then release the pull rod 18. The insertion block 15 automatically inserts into the slot 16 under the elastic force of the second spring 17, and the fixation of the first sub-foot 7 and the second sub-foot 8 can be completed. The structure is simple and the replacement is very convenient.

[0036] Finally, the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
