Embodiment 1

Refering to fig. 1, in the present embodiment, a kind of switch on wall is proposed, including key panel 1000, the upper casing set gradually 2000 and it is provided with the lower casing 3000 of pcb board 3100, wherein key panel 1000 and upper casing 2000 are rotatablely connected, upper casing 2000 snap on lower casing 3000.

As shown in Fig. 2, setting is in vacant state by pressure arm 1100 on key panel 1000, wherein used by pressure arm 1100 In the switch button 3110 of pressing pcb board 3100.Wherein, as shown in fig. 7, in the present embodiment, the schematic diagram of pcb board 3100.

To allow the switch button 3110 being pressed on pcb board 3100 by pressure arm 1100, as shown in Fig. 2, upper casing 2000 It is provided with the first through hole 2100 for making to pass through by pressure arm 1100.

Pressing keys panel 1000, key panel 1000 rotate, and turn by pressure arm 1100 with key panel 1000 is synchronous It is dynamic, the switch button 3110 on pcb board 3100 is then contacted and pressed, to realize the electric appliance being electrically connected with switch on wall Open or close.

When completing after opening or closing of electric appliance, external force is removed, at this point, key panel 1000 can be by resetting machine accordingly The movement of structure real resetting.

For solve the problems, such as key panel 1000 reset, can be arranged as follows in the present embodiment:

As shown in Figure 2 and Figure 4, key panel 1000 is provided with the first crotch 1200, upper casing towards upper casing 2000 on one side 2000 are provided with the second crotch 2200 in key panel 1000 opposite to each other on one side.Wherein, upper casing 2000 is provided with for making first The second through-hole 2210 that crotch 1200 passes through.

First crotch 1200 and the second crotch 2200 correspond, and the direction of the two hook groove is opposite.First crotch 1200 It can according to need and be configured with the quantity of the second crotch 2200, but the quantity of the two is consistent always.

For the equilibrium for guaranteeing stress, the first crotch 1200 may be configured as even number, and each first crotch 1200 is apart from key face The distance of the pivot center of plate 1000 is equal, correspondingly, distance of each second crotch 2200 apart from the pivot center is also equal. In the present embodiment, the quantity of the first crotch 1200 and the second crotch 2200 may be configured as 2, in other specific embodiments, The quantity of the two can also be configured as needed.

Referring to Fig. 6, for the reset for realizing key panel 1000, it is also necessary to for providing the component of reset response power, for this purpose, Tension spring 4000 can be arranged on first crotch 1200 and the second crotch 2200, one end of tension spring 4000 is set in the first crotch 1200 Hook groove in, the other end of tension spring 4000 is set in the hook groove of the second crotch 2200.Wherein, tension spring 4000 and the first crotch 1200 and second crotch 2200 be all one-to-one.

When no external force is when on key panel 1000, tension spring 4000 is in the state of nature elongation, once by pressing When keyboard plate 1000 makes it execute the movement of switch, tension spring 4000 can due between key panel 1000 and upper casing 2000 it is opposite away from From variation and be elongated；After external force is removed, tension spring 4000 can be gradually shortened under the action of elastic force to original state, Tension spring 4000 can apply rotating torque to key panel 1000 during shortening, so that the rotation of key panel 1000 is pulled, So that by pressure arm 1100 far from switch button 3110, it is thus achieved that the reset of key panel 1000.

Due to being pulled using tension spring 4000, so during pressing keys panel, the feel of operation compared to Traditional resetting-mechanism can be more preferable.

In the present embodiment, the pivot center of key panel 1000 is located at by pressure arm 1100 and the first crotch 1200 Two sides, and the first crotch 1200 and the second crotch 2200 are located at the ipsilateral of the pivot center of key panel 1000.

Wherein, the draw direction of tension spring 4000 is vertical with the pivot center of key panel 1000, in this way, tension spring 4000 provides Elastic force be more favorable for that key panel 1000 is driven to be rotated.

In the present embodiment, it is fixedly connected by one end of pressure arm 1100 with key panel 1000, other end setting is flexible Contact 1110, wherein the corresponding switch button 3110 of resilient contact 1110 simultaneously is used to press it, passes through resilient contact 1110 It can more convenient switch button 3110 for contacting and being pressed on pcb board 3100.

Since key panel 1000 and upper casing 2000 are rotatablely connected, for convenience of being assembled to the two, can carry out as follows Setting:

As shown in figure 3, key panel 1000 may be provided with linking arm 1300, linking arm 1300 towards upper casing 2000 on one side On may be provided with jack 1310.

It is corresponded with linking arm 1300 and as shown in figure 5, upper casing 2000 may be provided with for passing through linking arm 1300 Third through-hole 2300, wherein be provided with along the depth direction of third through-hole 2300 with jack 1310 be rotatablely connected connection Axis 2310.Meanwhile connecting shaft 2310 and jack 1310 correspond, connecting shaft 2310 is inserted into jack 1310 rotation company therewith It connects.

To keep structure more symmetrical beautiful, meanwhile, keep stress more balanced, linking arm 1300 may be configured as even number, In, jack 1310 and connecting shaft 2310 are respectively positioned on the pivot center of key panel 1000.In the present embodiment, linking arm 1300 And the quantity of third through-hole 2300 can be set to 4；In other specific embodiments, the quantity of the two can also be as needed It is configured.

Linking arm 1300 is aligned with corresponding third through-hole 2300, linking arm 1300 is inserted into corresponding third through-hole In 2300, later, snap into jack 1310 in corresponding connecting shaft 2310；Third through-hole 2300 is inserted into linking arm 1300 Meanwhile first crotch 1200 be also inserted into therewith in corresponding second through-hole 2210, correspondingly, being also targeted by first by pressure arm 1100 Through-hole；Then, tension spring 4000 is set on corresponding first crotch 1200 and the second crotch 2200, at this point, key panel Assembly working between 1000 and upper casing 2000 is just completed；Finally, upper casing 2000 is snapped on lower casing 3000.So far, just complete At the assembly work of switch on wall.

In the present embodiment, key panel 1000 may be configured as symmetrical structure, and linking arm 1300 is about key panel 1000 symmetrical center line is symmetrical, wherein the symmetrical center line of key panel 1000 turns perpendicular to key panel 1000 Shaft line.

Correspondingly, upper casing 2000 may be set to be symmetrical structure, first through hole 2100 be located at upper casing 2000 it is symmetrical in On heart line, wherein pivot center of the symmetrical center line of upper casing 2000 perpendicular to key panel 1000.

In the present embodiment, the first crotch 1200 can also about key panel 1000 symmetrical center line it is symmetrical, together When, the second crotch 2200 then can about upper casing 2000 symmetrical center line it is symmetrical.

Pcb board 3100 is one of core component, and it is more fragile, for convenience of pcb board 3100 is fixed and is protected, It may be provided with the fixing piece 3200 for fixing and protecting pcb board 3100 on lower casing 3000.Wherein, PCB can be screwed In on fixing piece 3200, and fixing piece 3200 can also be screwed on lower casing 3000.

As shown in figure 8, switch on wall needs to be installed on wall, for this purpose, settable mounting hole 3300 on lower casing 3000, In, lower casing 3000 is installed on wall for making to pass through by screw by mounting hole 3300.Lower casing 3000 is first fixed on wall, Wiring work is carried out later, is completed finally, being installed on lower casing 3000 in assembled key panel 1000 and upper casing 2000 The installment work of switch on wall.
