[0004] However, the push-button switches mentioned in the existing technology have a relatively slow switching process, resulting in poor power-off effect, safety hazards, and easy damage to the equipment used. Therefore, there is a need to design a switch that can switch on and off quickly. Utility Model Content

[0005] The purpose of this invention is to provide a fast-on / off switch to solve the problems in the prior art.

[0008] A movable contact rod is rotatably mounted on the conductive rod, and a torsion spring for pressing down the movable contact rod is fixed on the conductive rod. A movable component is slidably mounted inside the housing, and the movable component is connected to the button.

[0009] A control block is fixedly provided on one side of the moving part, and a horizontally arranged spring 2 is fixedly provided inside the control block.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model provides a fast on / off switch, which achieves tight contact between the moving contact and the stationary contact through a torsion spring inside the switch. The spring stores potential energy, and when the switch is turned off, the spring releases its elastic force to quickly push the push block up, so that the moving contact rod quickly separates from the stationary contact, thereby achieving the switch.

[0017] 2. This utility model provides a fast-on / off switch with a simple and compact internal structure. When the circuit is closed, the torsion spring presses firmly against the moving contact rod, and the baffle fixes the control block. When the circuit is disconnected, the control block moves quickly to push open the moving contact rod, thus providing a fast-on / off function. This ensures that the circuit is disconnected in a timely manner, which helps to protect the safety of the equipment used. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] A type of fast-on / off switch, such as Figures 1-6 As shown, the switch includes a housing 1, with an outer cover 11 fastened to one side of the housing 1. Four terminals 12 are fixedly provided on the housing 1, and a button 13 is provided on the housing 1. When the button 13 is pressed, it can control the rapid on / off switching of the switch. A movable part 14 is slidably provided inside the housing 1. A mounting groove 15 is provided on the movable part 14. A spring 16 is fixedly installed at one end of the movable part 14 and on one side of the mounting groove 15. The spring 16 supports the movable part 14. The other end of the movable part 14 is connected to the button 13.

[0029] Two terminals 12 located on one side of button 13 are each fixed with a stationary contact 17 at one end, and symmetrically distributed baffles 18 are fixed inside the housing 1, with the baffles 18 located on both sides of the moving part 14.

[0030] A conductive rod 19 is fixedly connected to each of the two terminals 12 on the other side of the button 13. A torsion spring 3 is fixedly installed on the conductive rod 19. A movable contact rod 2 is rotatably provided on the conductive rod 19. One end of the movable contact rod 2 is rotatably connected to the conductive rod 19, and the other end is fixedly connected to a movable contact 20. The stationary contact 17 is located below the movable contact 20.

[0031] The moving contact rod 2 has a slot 21. One end of the torsion spring 3 is connected to the slot 21 to press down the moving contact rod 2. When the switch is connected, the moving contact 20 on the moving contact rod 2 is connected to the stationary contact 17 to maintain stable circuit conduction.

[0032] A control block 4 is fixedly provided on one side of the movable part 14, and a connecting block 41 is fixedly installed on one side of the control block 4. The connecting block 41 is fixedly connected to the mounting groove 15. A second spring is fixedly provided inside the control block 4. The second spring is not shown in the figure. The second spring is horizontally installed inside the control block 4. Limit blocks 43 are fixedly connected to both ends of the second spring. When the button 13 is pressed down, the limit block 43 passes through the baffle 18 from top to bottom, and the second spring is compressed. Then, when the limit block 43 moves to the bottom of the baffle 18, the limit block 43 is locked under the bottom of the baffle 18, fixing the control block 4. The first spring 16 is in a compressed state. At this time, the torsion spring 3 presses down to connect the moving contact 20 on the moving contact rod 2 with the stationary contact 17.

[0033] Two push blocks 42 are fixedly provided on the control block 4. The two push blocks 42 are located below the two moving contact rods 2. When the switch is turned off, the control block 4 is pushed by the elastic force released by the spring-16 after its deformation. The push blocks 42 push the corresponding moving contact rods 2 upward, so that the moving contact rods 2 quickly disconnect from the stationary contact 17, thereby realizing the function of quick on and off.

[0034] The working principle is as follows:

[0035] After the wiring terminals 12 on the switch are connected to the circuit, when the control button 13 is pressed down, the limit block 43 passes the baffle 18 from top to bottom. The spring is compressed, allowing the limit block 43 to move smoothly past the baffle 18 to below the baffle 18. At this time, the limit block 43 is locked below the baffle 18, fixing the control block 4. The spring 16 is in a compressed state. At this time, the torsion spring 3 presses down to connect the moving contact 20 on the moving contact rod 2 with the stationary contact 17. The connection is stable and not easy to disconnect accidentally.

[0036] When button 13 is pressed again, releasing button 13 will control the switch to turn off. At this time, the elastic force stored in spring 16 is released, pushing control block 4 upward. Control block 4 is pushed by the elastic force released by spring 16 after its deformation, causing push block 42 on it to push moving contact rod 2 to rotate upward. At the same time, limit block 43 quickly passes over baffle 18, realizing the rapid disconnection of moving contact rod 2 from stationary contact 17, and realizing the function of rapid on / off switching.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
