Abstract
Description
Technical Field
[0001] The utility model specifically relates to a wall switch, in particular to a self-resetting wall switch. Background Art
[0002] At present, a wall switch is an electrical switch installed on a wall for use. It is not only a functional home decoration product, but also an electrical component used to connect and disconnect a circuit. The seesaw wall switch on the market adopts the principle of tilting up and down or swinging left and right. When the switch is not pressed, the switch panel tilts to one side, and when the switch is pressed, the switch panel tilts to the other side. There is always one side higher than the plane, making the switch surface button uneven. This feature of the seesaw switch will make it easy for dust to accumulate on its surface, causing edge jamming, while affecting the visual appearance, and cannot meet the new aesthetic requirements of modern people. Therefore, a press-plate flat wall switch begins to appear on the market. Although most of the press-plate flat wall switches can achieve a flat press plate or a small swing angle of the press plate, when the existing flat wall switch is used, it is necessary to press the on-zone or off-zone of the press plate respectively to realize the connection or disconnection of the wall switch, and the stability of the press plate action is poor, resulting in a poor pressing feel of the press plate and a short service life. Summary of the invention
[0003] The utility model aims to overcome the defects of the prior art and provide a self-resetting wall switch with simple structure, stable and reliable performance, long service life and good hand feeling.
[0004] To achieve the above-mentioned purpose, the utility model adopts a self-resetting wall switch, including a base, a pressure cover arranged in the base, a pressing plate arranged on the base, a moving contact, a static contact matched with the moving contact, a button rotatably arranged in the pressure cover and used to drive the moving contact to perform opening and closing actions, and a self-resetting driving mechanism arranged between the button and the pressing plate. The self-resetting driving mechanism includes two driving plates rotatably arranged on the pressure cover and linked with the pressing plate, a self-resetting component linked with the two driving plates and used to drive the button to perform opening and closing actions, and the self-resetting component includes A reset member slidably arranged in the pressure cover, a support member that cooperates with the reset member and is used to drive the button to perform opening and closing actions, and a reset spring arranged between the support member and the pressure cover. One side of one end of the two driving plates is respectively provided with a positioning groove on the reset member. One end of the reset member abuts in the positioning grooves of the two driving plates, and constitutes a linkage cooperation between the reset member and the two driving plates. A protrusion that cooperates with the two driving plates is arranged in the press plate. The protrusion abuts on the other side of one end of the two driving plates, and constitutes a linkage cooperation between the two driving plates and the protrusion.
[0005] The beneficial effect of the above structure is that a self-resetting driving mechanism is arranged between the pressing plate and the button, the pressing plate drives the self-resetting component through two driving plates, the self-resetting component drives the moving contact to move, and the wall switch is closed or opened, and the user only needs to press any position of the pressing plate to trigger the wall switch, which is more convenient to operate and has a better pressing feel. During operation, the user presses any position of the pressing plate, the pressing plate drives the two driving plates to move, the two driving plates drive the reset member to move, the reset member drives the support member to move, the support member compresses the spring and contacts the button, and the driving arm of the support member can drive the button to swing, thereby achieving the purpose of closing or opening the wall switch. After the user releases the pressing plate, the compressed spring drives the support member and the reset member to reset, the reset member drives the two driving plates to reset, and the two driving plates drive the pressing plate to reset, so that the pressing plate can maintain a flat state. Therefore, the appearance of the wall switch is more beautiful. Therefore, the self-resetting wall switch has the advantages of simple structure, stable and reliable performance, long service life and good feel.

[0007] In particular, a guide convex strip is respectively arranged on the other end of the two driving plates, and a guide groove matching the guide convex strip is arranged on the pressure cover, and the guide convex strip moves with the driving plates and reciprocates in the guide groove. The guide groove of the pressure cover guides the guide convex strips of the two driving plates, thereby ensuring that the two driving plates can reliably move on the pressure cover, which is beneficial to improving the working reliability of the self-resetting wall switch.
