During being installed in fixed part 24, positioning action is played.
The permanent magnet 32 is fixed on the middle part of the sliding part 31, the position of the permanent magnet 32 and the phase of the iron core 35
Correspond to and the permanent magnet 32 is plate-like, have two.Two spacing of permanent magnet 32 and the first side wall 352 and second
The spacing of side wall 353 is corresponding.In some implementations, two spacing of permanent magnet 32 and the first side wall 352 and
The spacing of two side walls 353 is equal.Two one end of permanent magnet 32 are away from on the first side wall 352 and second sidewall 353 respectively
The end thereof contacts of iron core bottom wall 351, or two one end of permanent magnet 32 respectively with the side wall 354 of second sidewall 353 and the 3rd on
It is away from the end thereof contacts of iron core bottom wall 351.Specifically, because the wireless passive switch 100 has two kinds of "ON" and "Off"
State, when the upper casing 10 of wireless passive switch 100 is pressed, upper casing 10 can rotate certain angle (that is, on relative to lower casing 20
Shell is tilted by one end, and the state that the other end falls becomes one end whereabouts, the state that the other end is tilted).Accordingly, in wireless and passive
Two one end of permanent magnet 32 in switch 100, by being away from iron core bottom with the first side wall 352 and second sidewall 353 respectively
The end thereof contacts of wall 351, are converted into being away from one end of iron core bottom wall 351 with the side wall 354 of second sidewall 353 and the 3rd respectively
Contact.
The wireless passive switch 100 also includes fixture 39, and the fixture 39 covers at the iron core 35 and fixes
In portion 24.The fixture 39 includes fixture upper wall 391, fixture lower wall 392, fixture side wall 393 and fixture roof
394.The left end of the fixture upper wall 391 and fixture lower wall 392 is consolidated with the upper and lower ends of fixture side wall 393 respectively
Fixed connection, the upper and lower ends of the fixture roof 394 are upper with the fixture upper wall 391 and fixture lower wall 392 respectively
End is fixedly connected.The downside (that is, at the lower right corner) of the right-hand member of the fixture upper wall 391 and fixture lower wall 392 is respectively provided with
There is holding board (3911,3921), the level height of holding board (3911, the 3921) lower surface is higher than the fixture upper wall
391 and fixture lower wall 392 lower end surface level height, and its difference in height is equal to first check plate 311 and the
The thickness of two check plates 312.The holding board (3911,3921), for pushing down the check plate of first check plate 311 and second
312, so that sliding part 31 is close to the lower casing 20, and then cause that the sliding part 31 can only do relative to lower casing 20
Lower slider.The fixture upper wall 391 and fixture lower wall 392 are also respectively provided with draw-in groove (3912,3922), the fixed part
24 upper wall 241 and the outer surface of lower wall 242 are also respectively provided with fixture block 2421, and the fixture block 2421 is embedded in the draw-in groove
In (3912,3922), so that the fixture 39 is realized snapping connection with the lower casing 20.The fixture 39 also sets up
Have a securing plate 395, the securing plate 395 respectively with the fixture upper wall 391, fixture lower wall 392 and fixture roof 394
It is fixedly connected, and the securing plate 395 is parallel to each other with fixture side wall 393.The side wall 243 of the fixed part 24 is remote
Clamping part 244 is additionally provided with from the side of the upper wall 241 and lower wall 242, the clamping part 244 is used to clamp the reinforcing
Plate 395, and then cause that the fixture 39 is more firm with being fixedly connected for the lower casing 20.Meanwhile, the securing plate 395 is also
The intensity of the entirety of the fixture 39 can be strengthened, and play a part of to strengthen sizing.
The operation principle of the wireless passive switch：The wireless passive switch has "ON" and "Off" two states, is pressing
When pressing the upper casing of wireless passive switch, upper casing can rotate certain angle relative to lower casing, and (that is, upper casing is tilted by one end, another
The state for falling is held to become one end whereabouts, the state that the other end is tilted).For ease of understanding and explaining, wireless passive switch is defined
"open" state, the state of corresponding upper casing falls for the upper end of upper casing, and lower end tilts；And the corresponding upper casing of "off" state
State for upper casing upper end tilt, lower end fall.Certainly, in actual production and when using, the structure setting can also make
Opposite.When wireless passive switch is transformed into "off" state by "open" state, the upper end of upper casing need to be pressed, now upper casing
Lug boss can to first connecting rod the other end apply pressure so that the corresponding lower casing of first connecting rod turns an angle, and
The angle of first connecting rod and lower casing is tapered into, so one end of first connecting rod and the distance between the other end of second connecting rod by
Gradual change is big.Second connecting rod promotes the first sliding block to move down, and the first sliding block compresses the first elastic portion during moving down
Part, the pressure transmission that the first elastomeric element will be subject to is to sliding part.Permanent magnet is fixed with sliding part, due to permanent magnet and iron core
Between have magnetic force, and iron core is fixed, so sliding part will not be moved or slide.When the first elastomeric element is compressed to
When to a certain degree, i.e., when the pressure for being transmitted to sliding part is more than the magnetic force between permanent magnet and iron core, sliding part is with permanent magnet
Slide from top to bottom.During movement, the magnetic field of permanent magnet is also moved permanent magnet, because iron core and coil are fixed
, permanent magnet is relatively moved relative to iron core and coil, and then causes the magnetic induction line in the coil cutting magnetic field, coil
Middle generation electric current.Electric current is transferred to radio communication device, from radio communication device to the communicator sending signal in light fixture, lamp
After tool receives the signal, realize that light fixture is changed into the state of " bright ".When wireless passive switch is transformed into "ON" by "off" state
State when, the operation principle of wireless passive switch is same as described above, will not be described here.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be in other specific forms realized.Therefore, no matter
