Correspondingly, in the fixing portion 24, fixing blocks 2411 are respectively disposed on inner sides of the upper wall 241 and the lower wall 242 near one end of the side wall 243, and the fixing blocks 2411 are elongated and are embedded in the fixing grooves 3511, so as to reinforce the iron core 35 and perform a positioning function during the process of mounting the iron core 35 in the fixing portion 24.
The permanent magnet 32 is fixed to the middle of the slider 31, the permanent magnet 32 is positioned corresponding to the iron core 35 and the permanent magnet 32 has a plate shape, and there are two.

Specifically, since the wireless passive switch 100 has two states, i.e., an "on" state and an "off" state, when the upper case 10 of the wireless passive switch 100 is pressed, the upper case 10 rotates by a certain angle with respect to the lower case 20 (i.e., the upper case is tilted from one end to another end, and the other end is tilted from one end to another end. Accordingly, one end of the two permanent magnets 32 in the wireless passive switch 100 is converted from being in contact with one end of the first side wall 352 and the second side wall 353, respectively, which is far from the core bottom wall 351, to being in contact with one end of the second side wall 353 and the third side wall 354, respectively, which is far from the core bottom wall 351.

The lower sides (i.e., at the lower right corners) of the right ends of the fixing upper wall 391 and the fixing lower wall 392 are respectively provided with a holding plate (3911, 3921), the lower surfaces of the holding plates (3911, 3921) are higher in level than the lower end faces of the fixing upper wall 391 and the fixing lower wall 392, and the difference in level is equal to the thicknesses of the first stopper plate 311 and the second stopper plate 312. The holding plates (3911, 3921) are used for pressing the first stop plate 311 and the second stop plate 312, so that the sliding piece 31 is tightly attached to the lower shell 20, and the sliding piece 31 can only slide up and down relative to the lower shell 20. The fixing upper wall 391 and the fixing lower wall 392 are further provided with clamping grooves (3912, 3922), the outer surfaces of the upper wall 241 and the lower wall 242 of the fixing part 24 are further provided with clamping blocks 2421, and the clamping blocks 2421 are embedded into the clamping grooves (3912, 3922), so that the fixing 39 is in snap connection with the lower shell 20. The fixing member 39 is further provided with a reinforcing plate 395, the reinforcing plate 395 is fixedly connected to the fixing member upper wall 391, the fixing member lower wall 392 and the fixing member top wall 394, respectively, and the reinforcing plate 395 is parallel to the fixing member side wall 393. The side wall 243 of the fixing portion 24 is further provided with a clamping portion 244 on a side far away from the upper wall 241 and the lower wall 242, and the clamping portion 244 is used for clamping the reinforcing plate 395, so that the fixing connection between the fixing member 39 and the lower shell 20 is firmer. Meanwhile, the reinforcement plate 395 can also strengthen the overall strength of the fixing member 39 and perform a reinforcing and shaping function.
The working principle of the wireless passive switch is as follows: the wireless passive switch has two states of on and off, when the upper shell of the wireless passive switch is pressed, the upper shell can rotate a certain angle relative to the lower shell (namely, the upper shell is turned from one end to the other end, and the other end is turned to the other end. For easy understanding and explanation, defining the "on" state of the wireless passive switch, wherein the corresponding upper shell is in a state that the upper end of the upper shell falls and the lower end is tilted; the upper shell corresponding to the off state is in a state that the upper end of the upper shell is tilted and the lower end of the upper shell falls. Of course, the arrangement may be reversed during actual production and use. When the wireless passive switch is changed from an on state to an off state, the upper end of the upper shell is required to be pressed, and at the moment, the protruding part of the upper shell can apply pressure to the other end of the first connecting rod, so that the first connecting rod rotates by a certain angle corresponding to the lower shell, the included angle between the first connecting rod and the lower shell is gradually reduced, and the distance between one end of the first connecting rod and the other end of the second connecting rod is gradually increased. The second connecting rod pushes the first sliding block to move downwards, the first sliding block compresses the first elastic component in the downward moving process, and the first elastic component transmits the received pressure to the sliding piece. The permanent magnet is fixed in the sliding piece, and the sliding piece cannot move or slide due to the magnetic force between the permanent magnet and the iron core and the fixed iron core. When the first elastic component is compressed to a certain degree, namely, the pressure transmitted to the sliding component is larger than the magnetic force between the permanent magnet and the iron core, the sliding component slides from top to bottom with the permanent magnet. In the moving process of the permanent magnet, the magnetic field of the permanent magnet also moves, and the iron core and the coil are fixed, so that the permanent magnet moves relatively to the iron core and the coil, and the coil cuts the magnetic induction line in the magnetic field, and current is generated in the coil. The current is transmitted to the wireless communication device, the wireless communication device sends a signal to the communication device in the lamp, and the lamp changes into a bright state after receiving the signal. When the wireless passive switch is changed from the off state to the on state, the working principle of the wireless passive switch is the same as that described above, and a detailed description is omitted here.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
