[0039] Driving plate 6, provided on the pressing plate 5 and matched with the swing lever 4, and used for driving the swing lever 4 to swing and / or horizontally slide. The utility model has the advantages that the vertical movement of the pressing plate drives the driving plate to act, so that the swing lever is moved to the position and the movable contact piece reliably acts to realize the conduction or disconnection of the circuit. The utility model also has the advantages of simple structure, convenient and reliable transmission, convenient assembly, long service life and the like.

[0040] The utility model also comprises:

[0041] Connecting seat 7, provided on the base 1, and the pressing plate 5 is provided on the connecting seat 7 and vertically moves relative to the connecting seat 7;

[0042] First reset member 71, provided on the connecting seat 7, and abutting with the pressing plate 5 and / or the driving plate 6, and used for resetting the pressing plate 5. The structure is convenient for the installation and reliable movement of the pressing plate. Specifically, the connecting seat is provided with a guide groove, the first reset member is provided in the guide groove, and the pressing plate is provided with a guide lug matched with the guide groove. The first reset member is provided to make the pressing plate quickly reset after pressing, and the structure is simple and convenient for resetting.

[0043] The driving plate 6 is provided with a driving part 61 for driving the swing lever 4 to rotate, and the swing lever 4 is provided with a swing lever transmission part 41 matched with the driving part 61. Specifically, the driving part 61 and the swing lever transmission part 41 both include an inclined surface, the swing lever 4 is connected with the connecting seat 7 through a swing lever shaft 42 and can rotate relative to the connecting seat 7, and the swing lever shaft 42 and the swing lever transmission part 41 are arranged on different sides of the swing lever 4. More specifically, the driving part 61 has two, and the swing lever transmission part 41 is arranged correspondingly with the driving part 61; when the pressing plate 5 is pressed, one of the two driving parts 61 is arranged on the outer side of the swing lever transmission part 41, and the other is arranged on the inner side of the swing lever transmission part 41; and the driving part 61 and the bottom surface of the driving plate 6 are matched with each other to make the swing lever 4 swing. In the actual operation process, when the pressing plate is pressed downward, the driving plate can be driven to move vertically downward; when one of the driving parts collides with one of the swing lever transmission parts, the driving plate slips relative to the pressing plate due to the gap, and continues to press down; at this time, the driving plate will slip horizontally and rotate around the rotating part as a fulcrum; at this time, the limiting part on the driving plate will play a role in limiting rotation, which makes the pressing plate move in the vertical direction with a smaller force, so that the driving plate moves vertically, horizontally and swings, thereby making the swing lever swing at a large angle, satisfying the stroke of the movable contact piece, and thus the faceplate (not marked in the drawing) can be avoided to protrude from the wall.

[0044] The driving plate 6 and the pressing plate 5 are matched with each other through an insertion shaft 62 and an insertion slot 51, the insertion shaft 62 is inserted into the insertion slot 51 to make the driving plate 6 and the pressing plate 5 horizontally slide and limit each other. Specifically, the driving plate 6 is provided with a reset shaft 63, the reset shaft 63 passes through the driving plate 6 and is arranged on the pressing plate 5 to reset the driving plate 6 after horizontal sliding. Figure 9 After the driving plate moves horizontally, it is reset horizontally through the reset shaft.

[0045] The driving plate 6 is provided with a connecting block 64, the connecting block 64 protrudes a rotating part 65 towards the pressing plate 5, and a gap 66 is arranged between the rotating part 65 and the pressing plate 5. The rotating part is arranged to facilitate the rotation of the driving plate, and the structure is simple; the gap can make the driving plate and the pressing plate have a certain vertical displacement (see Figure 9 ), so that the driving plate and the swing lever are matched and replaced, and the reliable electric swing lever swings.

[0046] The connecting block 64 protrudes to form a limiting part 67 towards the pressing plate 5, the horizontal height of the rotating part 65 is higher than that of the limiting part 67, and the rotating part 65 and the limiting part 67 are both arranged in a circular arc shape. The horizontal position of the rotating part is relatively high, so that the rotating part can be used as a fulcrum during pressing to make room for the rotation of the driving plate. When the limiting part collides with the inner wall of the pressing plate, it limits the movement, so that the product operates conveniently and reliably.

[0047] The pressing plate 5 is provided with mounting blocks 52, the mounting blocks 52 form mounting grooves 53, the connecting blocks 64 are inserted into the mounting grooves 53, the mounting blocks 52 are provided with limiting blocks 54 matched with the connecting blocks 64, and the reset shafts 63 pass through the mounting blocks 52 and are arranged on the pressing plate 5. Specifically, the limiting blocks are arranged in a semicircular shape. Such a structure can reliably limit the driving plate, so that the driving plate is convenient and reliable to install, and the resistance when the driving plate horizontally slides.
