Description

Technical Field

[0001] This utility model belongs to the field of switch technology, specifically a wall switch. Background Technology

[0002] A wall switch is an electrical device installed on a wall to control the on / off state of a circuit. Its common function is to turn lights on and off, and it is widely used in homes, offices, shopping malls and other places.

[0003] Existing wall switches are mainly composed of the following parts: housing, button plate, stationary contact, moving contact piece, operating mechanism, and wiring terminals. Their working principle is as follows: when the button plate is pressed, the button plate drives the moving contact piece to swing through the operating mechanism, so that the moving contact on the moving contact piece contacts or separates from the stationary contact, thereby realizing the conduction and disconnection of the circuit.

[0004] The existing wall switches have the following drawbacks: the traditional switch requires the button to swing at a large angle to achieve effective contact or separation of the contacts, which limits the thickness of the panel to the movement trajectory of the button and makes it difficult to further reduce the thickness. In order to meet the movement space required for the button to swing, the thickness of the switch panel protruding from the wall is generally quite thick, resulting in visual abruptness and limited aesthetics. Therefore, a wall switch is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing wall switches, a new type of wall switch is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A wall switch of this utility model includes a mounting base and a button plate rotatably mounted on the mounting base. Both sides of the mounting base are open structures. A contact box is mounted on one side of the mounting base through a snap-fit ​​structure. A first stationary contact and a second stationary contact are mounted in the contact box, and both pass through the contact box to connect to the wires in the bottom box. A stationary contact point is provided on the first stationary contact. A mounting ear is electrically connected to one side of the second stationary contact. A moving contact piece is rotatably mounted on and electrically connected to the mounting ear. A moving contact point is provided on the moving contact piece to cooperate with the stationary contact point. A linkage mechanism is mounted in the mounting base. The button plate reciprocates and pivots by pressing, and the linkage mechanism is linked to make the moving contact piece reciprocate and pivot, so as to make the moving contact contact or separate from the stationary contact, thereby realizing the power-on and power-off of the switch.

[0007] Preferably, the linkage mechanism includes a pivot seat rotatably mounted in the mounting base. One side of the pivot seat is slidably provided with a push rod for driving the movable contact plate to pivot via a sleeve and spring. It also includes two V-shaped connecting rods rotatably mounted in the mounting base and arranged in a vertically opposite mirror image. The inner side of the push plate is provided with a first abutting block and a second abutting block for driving the V-shaped connecting rods to swing. The V-shaped connecting rod includes a driving part that cooperates with the first abutting block and the second abutting block, and an abutting part that cooperates with the pivot seat to make it swing back and forth. The abutting parts of the two V-shaped connecting rods act on the same side ends of the pivot seat respectively.

[0008] Preferably, the lever arm length of the first abutment block driving its corresponding V-shaped link swings is different from the lever arm length of the second abutment block driving its corresponding V-shaped link swings, and the pressing resistance when pressing the first abutment block area of ​​the button plate is different from the pressing resistance when pressing the second abutment block area of ​​the button plate.

[0009] Preferably, the moving contact piece has a V-shaped structure, including a first contact portion and a second contact portion. The push rod contacts the first contact portion to make the moving contact and the stationary contact make contact and conduction, and the push rod contacts the second contact portion to separate the moving contact and the stationary contact.

[0010] Preferably, a soft pad is embedded in the side of the mounting base that is in contact with the wall.

[0011] Preferably, the mounting base has a retaining strip on its periphery, and the thickness of the retaining strip is greater than the height of the gap after the mounting plate is raised.

[0012] Preferably, the button is composed of a reflective layer and a surface layer, wherein the reflective layer contains a light-absorbing, light-storing fluorescent coating, and the surface layer is a concave-convex prism array structure that reflects light.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a wall switch. By setting a linkage mechanism consisting of a pivot seat, a top rod and vertically opposing V-shaped connecting rods in the mounting base, the small-angle swing of the button is converted into an effective pivot of the moving contact piece by utilizing the leverage amplification effect of the V-shaped connecting rod. This greatly reduces the rotation angle of the button itself, eliminating the need to reserve a large space for the button's movement, thereby significantly reducing the panel thickness and improving aesthetics.

[0015] By setting a first abutting block and a second abutting block, and making the lever arm lengths of the corresponding V-shaped connecting rods different, a differentiated pressing resistance design is achieved for different areas of the button, forming a tactile distinction of "light press to turn on, heavy press to turn off". This allows users to intuitively judge the switch status through touch, reducing misoperation and is also suitable for blind users. Attached Figure Description

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Specific implementation examples are given below.

[0022] Please see Figure 1The wall switch of this utility model includes a mounting base 1 and a push plate 2 rotatably mounted on the mounting base 1. Both sides of the mounting base 1 are open structures. A contact box 3 is mounted on one side of the mounting base 1 via a snap-fit ​​structure. A first stationary contact 4 and a second stationary contact 5 are mounted inside the contact box 3, and both pass through the contact box 3 to connect to the wires inside the base box 01. The first stationary contact 4 is provided with a stationary contact point 401. A mounting ear 501 is electrically connected to one side of the second stationary contact 5. A moving contact piece 502 is rotatably mounted on and electrically connected to the mounting ear 501. The moving contact piece 502 is provided with a contact point that interacts with the stationary contact point 401. The moving contact 503 is matched with point 401. The mounting base 1 is equipped with a linkage mechanism 6. The push plate 2 reciprocates by pressing and links the linkage mechanism 6 to reciprocate the moving contact 502, so as to make the moving contact 503 contact or separate from the stationary contact 401, thereby realizing the energization and de-energization of the switch. The moving contact 502 has a V-shaped structure, including a first contact part 5021 and a second contact part 5022. The push rod 602 contacts the first contact part 5021 to make the moving contact 503 contact and the stationary contact 401 to conduct electricity. The push rod 602 contacts the second contact part 5022 to separate and disconnect the moving contact 503 from the stationary contact 401.

[0023] The linkage mechanism 6 includes a pivot seat 601 rotatably mounted in the mounting base 1. A push rod 602 for driving the movable contact piece 502 to pivot is slidably disposed on one side of the pivot seat 601 via a sleeve and spring. It also includes two V-shaped connecting rods 603 rotatably mounted in the mounting base 1 and arranged in a vertically opposite, mirror-like configuration. A first abutting block 7a and a second abutting block 7b for driving the V-shaped connecting rods 603 to swing are disposed on the inner side of the pressing plate 2. Each V-shaped connecting rod 603 includes a driving part 6031 that cooperates with the first abutting block 7a and the second abutting block 7b, and a part that interacts with the pivot seat 601. The abutment portion 6032, which cooperates with the reciprocating swinging of the two V-shaped connecting rods 603, acts on the same side ends of the pivot seat 601. The lever arm length of the first abutment block 7a driving its corresponding V-shaped connecting rod 603 to swing is different from the lever arm length of the second abutment block 7b driving its corresponding V-shaped connecting rod 603 to swing. The pressing resistance when pressing the first abutment block 7a area of ​​the button plate 2 is different from the pressing resistance when pressing the second abutment block 7b area of ​​the button plate 2. During operation, when the user needs to control the switch to turn on the power, pressing the button plate 2 as shown in the image... Figure 1On the lower middle side, the second abutment block 7b on its inner side pushes the driving part 6031 of the lower V-shaped connecting rod 603 to swing towards the inside of the bottom box 01. Due to the lever amplification effect formed by the shape and structure of the V-shaped connecting rod 603, when the button plate 2 swings at a small angle, the abutment part 6032 of the V-shaped connecting rod 603 drives the pivot seat 601 to rotate significantly around its axis, and drives the top rod 602 on one side to swing forward. The front end of the top rod 602 abuts against the first contact part 5021 of the moving contact piece 502. Because the moving contact piece 502 rotates around the mounting ear 501, the top rod 602 synchronously pushes the moving contact piece 502 to swing, so that the moving contact 503 contacts the stationary contact 401 to realize the circuit conduction. After the button plate 2 is released, the elastic force of the spring always pushes the top rod 602 to abut against the first contact part 5021, so that the switch remains in the conducting state. When it is necessary to turn off the switch, the top side of the button plate 2 can be pressed according to the above principle, and the principle is the same as above. The details will not be elaborated here. Since the lever arm of the first abutment block 7a and the corresponding V-shaped link is relatively long, according to the lever principle, the required pressing force is smaller under the same resistance, so the resistance of pressing this area is lighter. On the other hand, the lever arm of the second abutment block 7b and the corresponding V-shaped link is shorter, and the required pressing force is greater under the same resistance, so the resistance of pressing this area is heavier. The difference in lever arm between the two forms a pressing resistance gradient, realizing the tactile distinction of "light press to turn on, heavy press to turn off". Through the lever amplification effect of the linkage mechanism 6, the swing stroke of the button 2 is converted into the effective pivot of the moving contact piece 502, and the rotation angle of the button 2 itself (i.e. the angle between the button 2 and the wall 02) is greatly reduced, so that the thickness of the button 2 can be greatly reduced. At the same time, the panel does not need to reserve a large space for the movement of the button 2, the thickness is greatly reduced, the aesthetics are significantly improved, and users can intuitively distinguish the switch status by touch, reducing accidental operation at night or in low light.

[0024] Furthermore, a soft pad 8 is embedded in the side of the frame of the mounting base 1 that is in contact with the wall 02. During operation, when the switch is installed, the mounting base 1 is fixed to the base box 01 with screws. The panel frame of the mounting base 1 is in contact with the surface of the wall 02. The soft pad 8 is compressed and undergoes elastic deformation, tightly filling the gap between the mounting base and the wall to form a flexible sealing layer. The soft pad 8 prevents dust and moisture from entering the switch through the installation gap and can also buffer the rigid contact between the wall and the mounting base, avoiding abnormal noise caused by vibration when pressing the button 2, thus improving the user experience. Moreover, the embedded soft pad 8 does not increase the thickness of the edge of the panel of the mounting base 1.

[0025] Furthermore, a baffle 9 is provided around the edge of the mounting base 1. The thickness of the baffle 9 is greater than the height of the gap after the button plate 2 is raised. During operation, the button plate 2 itself is in a naturally raised state, and a gap is generated between it and the panel of the mounting base 1. The baffle 9 covers the gap, which can prevent external impurities from entering the switch.

[0026] Furthermore, the button 2 is composed of a reflective layer 201 and a surface layer 202. The reflective layer 201 contains a light-absorbing, light-storing fluorescent coating, and the surface layer 202 has a concave-convex prism array structure that reflects light. During operation, during the day, when ambient light shines on the button 2, the reflective layer 201 of the light-storing fluorescent coating absorbs and stores light energy. At night or when the light is dim, the reflective layer releases the stored light energy. The light is refracted by the prism array of the surface layer 202, and uniform light spots are visible from various angles on the surface of the button 2, indicating the switch position. The concave-convex structure of the prism array not only improves visibility but also enhances the friction and anti-slip properties of the button 2.
