Description

Technical Field

[0002] Current wall switches typically employ complex mechanical structures to control their opening and closing. For example, two sets of conductive copper plates are positioned opposite each other inside the switch housing, with a swingable connector between them. A pressure plate is located on the top of the switch housing; pressing the pressure plate controls the swing of the connector, which in turn connects the two sets of conductive copper plates, thus controlling the switch's opening and closing. This complex mechanical structure results in a large overall size for the switch. Utility Model Content

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[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 protection scope of the present utility model.

[0028] Please refer to Figures 1 to 9 This utility model proposes a switch. A preferred embodiment of the switch includes: an upper cover 1, a lower cover 2, a pressure plate 3, a flexible micro switch, a first PCB board 4, a second PCB board 5, a controller 6, and a relay 7. The upper cover 1 and the lower cover 2 are detachably connected and form a cavity for mounting the pressure plate 3, the flexible micro switch, the first PCB board 4, the second PCB board 5, and the relay 7. The first PCB board 4 is disposed above the second PCB board 5 and is connected to the second PCB board 5 via a connector. The relay 7 is disposed at the bottom of the second PCB board 5. The flexible micro switch and the controller 6 are disposed on the upper surface of the first PCB board 4. The pressure plate 3 is movably disposed on the upper cover 1 and contacts the flexible micro switch. The controller 6 is signal-connected to the flexible micro switch and the relay 7 respectively, and is used to control the opening and closing of the relay 7 according to the state of the flexible micro switch.

[0029] Furthermore, in this embodiment, the elastic micro switch includes a tactile switch 8, a spring seat 9, and a spring 10. The spring seat 9 has a hollow structure, and the tactile switch 8 is disposed in the cavity. The tactile switch 8 is lower than the top surface of the spring seat 9. The tactile switch 8 and the spring seat 9 are disposed on the first PCB board 4. The spring 10 is sleeved on the outer periphery of the spring seat 9. In its natural state, the spring 10 extends beyond the top surface of the spring seat 9 and contacts the lower surface of the pressure plate 3. A protrusion 11 is provided at the middle position of the lower surface of the pressure plate 3. When the pressure plate 3 is pressed down, the protrusion 11 contacts the tactile switch 8.

[0030] In this embodiment, the relay 7 can be either a normally open relay 7 or a normally closed relay 7. This embodiment uses a normally open relay 7 as an example to illustrate the present invention.

[0031] When the pressure plate 3 is pressed down until the protrusion 11 contacts the tactile switch 8, the controller 6 controls the relay 7 to close, thereby controlling the entire switching power supply to close. When the pressure plate 3 is released, the pressure plate 3 moves upward under the action of the spring 10, and the protrusion 11 moves away from the tactile switch 8. When the pressure plate 3 is pressed down again until the protrusion 11 contacts the tactile switch 8, the controller 6 controls the relay 7 to open, thereby controlling the entire switching power supply to close.

[0032] The circuit structure of the controller 6, relay 7, and switching power supply is as follows: Figures 7 to 9 As shown, the specific circuits of the controller 6, relay 7, and switching power supply will not be described in detail here.

[0033] Furthermore, in this embodiment, buckles 12 are provided on both sides of the pressure plate 3, and the inner wall of the upper cover 1 is provided with a sliding groove corresponding to the buckles 12, and the buckles 12 are slidably disposed in the sliding groove.

[0034] When the pressure plate 3 is pressed, the buckle 12 drives the entire pressure plate 3 to move downward along the slide groove until the protrusion 11 contacts the tactile switch 8; when the pressure plate 3 is released, the pressure plate 3 slides upward along the slide groove under the elastic force of the spring 10, and at the same time, when the buckle 12 slides to the top of the slide groove, it can play a limiting role.

[0035] Furthermore, in this embodiment, three capacitors are connected in parallel on the second PCB board 5: capacitor C13, capacitor C17, and capacitor C18.

[0036] In this embodiment, capacitors C13, C17, and C18 are part of the switching power supply circuit. In the prior art, a single capacitor is usually used, but this results in a large size, which is not conducive to the assembly of other electronic components in the switching power supply. Therefore, this invention replaces the single capacitor in the prior art with three smaller capacitors connected in parallel to reduce the overall size of the switching power supply.

[0037] Furthermore, in this embodiment, a switch light guide post 13 is provided on the first PCB board 4.

[0038] Furthermore, three flexible terminals 14 and a terminal fixing seat 15 for fixing the terminals 14 are arranged side by side at one end of the lower cover 2, as well as a conductive copper sheet 16 that contacts the flexible terminals 14.

[0039] The flexible terminal 14 includes an L-shaped first contact portion 17 and an L-shaped second contact portion 18. The top connection between the first contact portion 17 and the second contact portion 18 is an arc-shaped surface. The free end of the first contact portion 17 is connected to the conductive copper sheet 16.

[0040] The bottom of the lower cover 2 is provided with a slot 19, and the conductive copper sheet 16 is located in the slot 19 with a gap between it and the slot 19.

[0041] When connecting cable 21, insert cable 21 through the insertion hole 20 at the bottom of the lower cover 2 between the terminal block 14 and the terminal block fixing seat 15 to fix cable 21. When it is necessary to remove cable 21, insert an external tool into the slot 19 and move the conductive copper piece 16. The conductive copper piece 16 will cause the terminal block 14 to move backward and separate from cable 21, and then cable 21 can be easily pulled out.

[0042] In summary, the beneficial effects of this utility model switch are:

[0043] This utility model, through the above-described technical solution, includes: an upper cover, a lower cover, a pressure plate, a flexible micro switch, a first PCB board, a second PCB board, a controller, and a relay. The upper cover and the lower cover are detachably connected, forming a cavity for housing the pressure plate, the flexible micro switch, the first PCB board, the second PCB board, and the relay. The first PCB board is positioned above the second PCB board, and the first PCB board and the second PCB board are connected via a connector.
