       BACKGROUND OF THE PRESENT INVENTION 
       [0003]    1. Field of Invention 
         [0004]    The present invention relates to a wireless switch, and more particular to a self-power wireless switch. 
         [0005]    2. Description of Related Arts 
         [0006]    With the advent of high technology, the electronic industry has experienced very significant growth that that wireless controllers are commonly utilized in different electronic controlling device. Even though such wireless controllers bring us convenience, thousands of old wireless controllers will pollute our environment and waste our resources. 
         [0007]    Firstly, the wireless controller must be powered by batteries as a power source. Therefore, the user must frequently replace the old batteries with new batteries after a period of time usage. The operating cost for the wireless controller will be significantly increased by the batteries. Since most of the batteries are disposable, the old batteries will pollute our environment. Accordingly, land pollution is aggravated because of the wasted electronic components, such that many countries issue strict environmental regulations for those electronic wastes. 
         [0008]    Accordingly, most indoor illuminating devices generally comprise a wall controlling switch electrically connected to an illuminator via an electrical wire for controlling the illuminator in an on-and-off manner. In particular, the wiring configuration must be pre-designed in a floor plan of the building to illustrate the exact location of the controlling switch to run the electrical wire from the illuminator to the controlling switch. In addition, a switch box, PVC wire sleeve, and electric wires must be embedded into the wall by pre-forming a wire running groove in the wall. The installation not only takes times but also wastes lots of different materials. More importantly, it is impossible to re-locate the controlling switch. Otherwise, the wall must be damaged to form another wire running groove for the new electrical wire. Safety concerns are other issues that the switch box and the PVC wire sleeve must provide moisture prevention and explosion protection. 
         [0009]    In order to solve the above problems, the indoor illuminating device incorporates with a wireless switch wirelessly connected to the illuminator for controlling the illuminator in an on-and-off manner. However, the existing wireless switch has several drawbacks. (1) The users are not used to recharge the wireless switch via an external power outlet, such as a wall outlet, for operating the illuminator. (2) It is a hassle to find the wireless switch as it is considered as a portable device to be stored at any location of the building. (3) When the wireless switch is designed to be affixed on the wall structure, the wireless switch must be powered by batteries. Therefore, the user must replace the batteries frequently after a period of time. In particular, the user must detach the wireless switch from the wall and disassemble the outer casing of the wireless switch for cleaning and replacing the batteries. Otherwise, the battery acid will leak out of the battery to pollute the environment and to shorten the service life span of the battery. As result, the wireless switch cannot be widely used due to the above drawbacks. 
       SUMMARY OF THE PRESENT INVENTION 
       [0010]    The invention is advantageous in that it provides a self-powered wireless switch which is reliable, safe, and convenient with a remote switch, and can be widely used in everyday life.

         [0013]    Accordingly, the self-powered wireless switch further comprises a supporting panel, wherein the micro generator is supported by the supporting panel. Two sliding panels are symmetrically and spacedly extended from the supporting panel, wherein each of the sliding panels has a sliding groove formed thereat. Two sides of the magnet assembly are engaged with the sliding grooves of the sliding panels in a slidably movable manner. 
         [0014]    Preferably, one end of the coil core is extended out of the coil wire to define a protrusion portion, wherein the extension portion of the coil core is contacted with the magnet conductive panels. 
         [0015]    Accordingly, two extension portions of the magnet conductive panels are extended out of the permanent magnet to define a magnetic cavity between the extension portions. The protrusion portion of the coil core is disposed within the magnetic cavity, wherein when the magnetic assembly is moved up-and-down, the protrusion portion of the coil core can be moved within the magnetic cavity to contact with inner sides of the extension portions of the magnet conductive panels in an alternating manner. 
         [0016]    Accordingly, the magnet assembly further comprises an outer supportive frame having an interior cavity, wherein the permanent magnet and the magnet conductive panels are supported within the interior cavity of the outer supportive frame. The outer supportive frame further has two sliding members extended from two sides thereof to slidably engage with the sliding grooves of the sliding panels respectively. 
         [0017]    Accordingly, the supporting panel further has a protruded signal generator wherein a mid-portion of the switch panel is pivotally coupled at the protruded platform of the supporting panel, so as to pivotally couple the switch panel on the supporting panel. The magnet assembly is coupled at one end of the switch panel and the coil assembly is affixed at the supporting panel. 
         [0018]    Accordingly, the switch panel further has two engaging arms extended from two sides thereof and two engaging clips integrally formed at two free ends of the engaging arms respectively. The engaging clips are detachably engaged with the outer supportive frame. 
         [0019]    Accordingly, the switch panel has a panel cavity formed at a bottom side thereof, wherein the magnet assembly is coupled at the inner wall of the panel cavity of the switch panel. 
         [0020]    Accordingly, a resilient element has one end coupled at the supporting panel and another end coupled at the coil core. 
         [0021]    Accordingly, the coil core, having a W-shape, comprises a mid core arm and two side core arms, wherein the mid core arm is spacedly located between the two side core arms. The resilient element, having a U-shape, is overlapped on the coil core. The resilient arms of the resilient element are longer than the side core arms of the coil core. The resilient arms of the resilient element are coupled at the supporting panel. 
         [0022]    The coil core has a mid core body where the wire coil are wound therearound, a first core arm, and a second core arm, wherein the first and second core arms are oppositely and alignedly extended from the mid core body. The first core arm is pivotally coupled at the supporting panel to enable the rotation of the coil core. The second core arm is extended within the magnetic cavity. The magnet assembly is affixed on the supporting panel. 
         [0023]    The self-powered wireless switch further comprises an outer frame formed in a ring shape to couple at the peripheral portions of the supporting panel and the switch panels.

         [0025]    Comparing to the existing switch, the present invention provides the self-powered wireless switch to generate an induced current by an actuation of the switch panel to create a movement between the magnet assembly and the coil assembly. Therefore, the self-powered wireless switch can convert the mechanical energy from the switch panel to the electrical energy by the micro generator as a power supply for the control panel to transmit the wireless control signal.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0041]    The following description is disclosed to enable any person skilled in the art to make and use the present invention. Preferred embodiments are provided in the following description only as examples and modifications will be apparent to those skilled in the art. The general principles defined in the following description would be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention. 
         [0042]    Referring to  FIGS. 1 to 11  of the drawings, a self-powered wireless switch  1  according to a preferred embodiment of the present invention is illustrated, wherein the self-powered wireless switch  1  is adapted to incorporate with any electronic device. In particular, the self-powered wireless switch  1  is a self-powered unit for controlling the electronic device in an on-and-off manner. For example, the self-powered wireless switch  1  according to the preferred embodiment is arranged to control an illuminator in an on-and-off manner. It is appreciated that the self-powered wireless switch  1  can switch on and off other electronic devices such as television, refrigerator, and electric fan. 
         [0043]    As shown in  FIGS. 1 to 4 , the self-powered wireless switch  1  comprises a supporting panel  13  serving as a base panel, at least a micro generator  14  supported on the supporting panel  13 , a control panel  15 , and a switch panel  12 . The control panel  15  is a signal transmitter for transmitting a wireless control signal. In other words, when the control panel  15  is activated, the control panel  15  will generate and transmit the wireless control signal to the electronic device in order to control the electronic device, such as switch on the electronic device or switch off the electronic device. 
         [0044]    The micro generator  14  comprises a magnet assembly  144  supported in a movable manner and a coil assembly coupled at the supporting panel. The magnet assembly  14  comprises a permanent magnet  1443  and two magnet conductive panels  1442 , wherein the magnet conductive panels  1442  are located at two opposite poles (N-S) of the permanent magnet  1443  at two sides thereof respectively. In other words, the magnet conductive panels  1442  are magnetized by the permanent magnet  1443  to form two opposite magnetic poled panels respectively. The coil assembly comprises a coil core  142 , such as an iron core, and a coil wire wound around the coil core  142  to form a magnetic coil  147 , wherein the coil wire is electrically linked to the control panel  15 . According to the Faraday&#39;s Law of Induction, when the line of the magnetic force of the coil core  142  is changed to generate an electromotive force, an induced current is generated by the magnetic coil  147  via the coil wire. 
         [0045]    As shown in  FIGS. 2, 7, and 8 , the magnet assembly  144  is located at a first side (right side) of the coil core  142 , wherein a face (left face) of one of the magnet conductive panels  1442  is contacted with a face (right face) of the coil core  142 . In particular, the magnet assembly  144  is movable in relation to the coil core  142 , such as an up and down sliding movement. The magnet assembly  144  is arranged at one side of the coil assembly facing the centerline of the magnetic coil  147 , such that the coil core  142  perpendicularly faces toward the magnet assembly  144 . It is worth mentioning that the coil core  142  can faces toward the magnet assembly  144  at any angle in order to magnetically induce with the coil core  142  and to change the line of the magnetic force of the coil core  142  for generating the induced current. 
         [0046]    According to the preferred embodiment, the micro generator  14  further comprises two sliding panels  143  symmetrically and spacedly extended from the supporting panel  13  to form a sliding cavity between the sliding panels  143 , wherein each of the sliding panels  143  has a sliding groove formed thereat, such that the sliding grooves of the sliding panels  143  face toward each other. Two sides of the magnet assembly  144  are engaged with the sliding grooves of the sliding panels  143  in a slidably movable manner, such that the magnet assembly  144  is movably supported at the sliding cavity. Accordingly, the sliding displacement of the magnet assembly  144  is restricted by the length of the sliding groove, so as to limit the up-and-down sliding movement of the magnet assembly  144 . In other words, the magnet assembly  144  is retained by the sliding panels  143  to ensure the coil core  142  to perpendicularly face toward the magnet assembly  144 . 
         [0047]    Accordingly, the magnet assembly  144  further comprises an outer supportive frame  1441  having an interior cavity  1444 , wherein the permanent magnet  1443  and the magnet conductive panels  1442  are supported within the interior cavity  1444  of the outer supportive frame  1441 . Therefore, the permanent magnet  1443  can be securely retained between the two magnet conductive panels  1442  to prevent any unwanted movement between the permanent magnet  1443  and each of the magnet conductive panels  1442 . The outer supportive frame  1441  further has two sliding members  1445  extended from two sides thereof to slidably engage with the sliding grooves of the sliding panels  143  respectively, such that the magnet assembly  144  can be slid at the sliding grooves of the sliding panels  143  in an up-and-down movable manner. 
         [0048]    As shown in  FIGS. 1, 5, and 6 , the supporting panel  13  further has a protruded platform  131 , wherein a mid-portion of the switch panel  12  is pivotally coupled at the protruded platform  131  of the supporting panel  13 , so as to pivotally couple the switch panel  12  on the supporting panel  13 . The switch panel  12  has a panel cavity formed at a bottom side thereof, wherein a pivot arm  121  is extended from the panel cavity of the switch panel  12  at the mid-portion thereof to pivotally couple with the protruded platform  131 , such that the switch panel  12  forms a seesaw panel on the supporting panel  13 . A first end (right end) of the switch panel  12  is coupled to the magnet assembly  144 , wherein when an opposed second end of the switch panel  12  is actuated, the first end thereof is pivotally moved to drive the magnet assembly  144  to reciprocatingly move up-and-down. Therefore, the permanent magnet  1443  and the magnet conductive panels  1442  are moved at the same time, such that the magnet conductive panels  1442  are aligned with the coil core  142  in an alternating manner, as shown in  FIGS. 7 and 8 . In other words, one of the magnet conductive panels  1442  will align with the coil core  142  when the magnet assembly  144  is moved upward while another magnet conductive panel  1442  will align with the coil core  142  when the magnet assembly  144  is moved downward. Since the magnet conductive panels  1442  have two opposite poles respectively, i.e. one magnet conductive panel  1442  has a N pole and another one has a S pole, the movement of the magnet assembly  144  will magnetically induce with the coil core  142  to change the line of the magnetic force of the coil core  142  so as to generate the induced current by the magnetic coil  147 . The current generated by the magnetic coil  147  will guide to flow to the control panel  15  as a power supply thereof in order to ensure the control panel  15  to be powered to transmit the wireless control signal for controlling the electronic device. It is worth mentioning that the magnet assembly  144  is coupled at the first end of the switch panel  12  at a position that the magnet assembly  144  is supported within the panel cavity of the switch panel  12 . In particular, the magnet assembly  144  is coupled at the inner wall of the panel cavity of the switch panel  12  to securely retain the magnet assembly  144  in position. Accordingly, the switch panel  12  further has two engaging arms  123  extended from two sides thereof and two engaging clips  124  integrally formed at two free ends of the engaging arms  123  respectively. The magnet assembly  144  is supported within the panel cavity of the switch panel  12  at a position between the two engaging arms  123 , wherein the engaging clips  124  are detachably engaged with the outer supportive frame  1441 , so as to prevent the magnet assembly  144  being detached from the switch panel  12  due to the movement of the magnet assembly  144 . 
         [0049]    As shown in  FIGS. 2 and 10 , the coil assembly further comprises a resilient element  141 , wherein one end of the resilient element  141  is affixed to the supporting panel  13  while another opposed end of the resilient element  141  is coupled to a second side of the coil core  142 , such that the opposed first side of the coil core  142  faces toward the magnet assembly  144 . Accordingly, the resilient element  141  having a U-shape is supported in a suspending manner, wherein a free end portion of the resilient element  141  is coupled with the second side of the coil core  142 , such that the first side of the coil core  142  is suspendedly supported toward the magnet assembly  144 . As shown in  FIG. 7 , when the magnet assembly  144  is moved downwardly, a magnetic attracting force between the magnet assembly  144  and the coil core  142  will generate to pull the coil core  142  downward so as to bend the resilient element  141  downward for restoring a resilient force thereof. When the magnet assembly  144  is kept moving downwardly, the resilient force of the resilient element  141  will transform as a reaction force to the coil core  142 . When the reaction force of the resilient element  141  is greater than the magnetic attracting force, the resilient element  141  will rapidly bend upwardly to its original form to rapidly move the coil core  142  upward, so as to rapidly change the line of the magnetic force of the coil core  142 . In other words, the magnetic coil  147  will generate a large amount of the induced current. Likewise, as shown in  FIG. 8 , when the magnet assembly  144  is moved upwardly, the magnetic attracting force between the magnet assembly  144  and the coil core  142  will generate to pull the coil core  142  upward so as to bend the resilient element  141  upward for restoring the resilient force thereof. When the magnet assembly  144  is kept moving upwardly, the resilient force of the resilient element  141  will transform as the reaction force to the coil core  142 . When the reaction force of the resilient element  141  is greater than the magnetic attracting force, the resilient element  141  will rapidly bend downwardly to its original form to rapidly move the coil core  142  downward, so as to rapidly change the line of the magnetic force of the coil core  142 . In other words, the magnetic coil  147  will generate a large amount of the induced current. 
         [0050]    Accordingly, the magnet conductive panels  1442  are directly contacted with the coil core  142 , wherein the magnet conductive panels  1442  are magnetically attracted to the coil core  142  when the magnet conductive panels  1442  are moved up and down. In other words, through the magnetic attraction, the coil core  142  is driven to move up and down corresponding to the movement of the magnet conductive panels  1442 . Therefore, the resilient element  141  is bent correspondingly. Once the reaction force of the resilient element  141  is greater than the magnetic attracting force, the reaction force of the resilient element  141  will break the magnetic attraction between the magnet conductive panels  1442  and the coil core  142 . Accordingly, the U-shaped resilient element  142  defines a mid-portion and forms a resilient platform to couple with the coil core  142 , and two resilient arms extended from the mid-portion, such that when the resilient arms are bent, the mid-portion of the resilient element  142  can be rapidly rebounded to move the coil core  142  back to its original position, so as to prevent a distortion of the coil core  142 . 
         [0051]    As shown in  FIGS. 2 and 10 , the coil core  142 , having a W-shape, comprises a mid core arm  1421  and two side core arms  1422 , wherein the mid core arm  1421  is spacedly located between the two side core arms  1422 . The coil wire is wound around the mid core arm  1421  to form the magnetic coil  147  and to define a protrusion portion of the coil core  142  at a free end of the mid core arm  1421 . The coil core  142  is overlapped on the resilient element  141  at a position that the mid-portion of the resilient element  142  is affixed to a portion of the coil core  142  above the side core arms  1422 . It is appreciated that the shape of the resilient element  141  can be modified as long as the resilient element will provide enough resilient force to the coil core  142  so as to ensure the coil core  142  to return back to its position in response to the movement of the magnet assembly  144 . According to the preferred embodiment, the coil core  142  is overlapped on and affixed to the resilient element  141  via a rivet  24 . It is appreciated that other fasteners can be used for affixing the coil core  142  to the resilient element  141 . Accordingly, the resilient arms  1411  of the resilient element  141  are longer than the side core arms of the coil core  142 , wherein the resilient arms  1411  of the resilient element  141  are affixed to two retention posts  145  integrally protruded from the supporting panel  13 , such that the mid core arm  1421  of the coil core  142  is perpendicular to the magnet assembly  144 . Accordingly, the magnetic coil  147  has at least 300 turns of coil wire. The induced voltage generated is proportional to the number of turns which the flux penetrates. Accordingly, every actuation of the switch panel  12  will cause the micro generator  14  to generate voltage. In each actuation of the switch panel  12 , the generation time of the micro generator  14  is about 1.5 ms, the voltage generated by the micro generator  14  is about 9V-15V, and the current generated by the micro generator  14  is about 30 mA. It is worth mentioning that the number of turns of the magnetic coil  147 , the size of the magnetic coil  147 , and the strength of the magnetic field will be the factors to generate different voltage and current output. 
         [0052]      FIG. 11  illustrates an alternative mode of the magnet assembly which comprises a permanent magnet  212  and two magnet conductive panels  211  to sandwich the permanent magnet  212  therebetween, wherein the length of the permanent magnet  212  is shorter than the length of each of the magnet conductive panels  211 , such that when the magnet conductive panels  211  are overlapped coupled at two sides of the permanent magnet  212  respectively, two extension portions of the magnet conductive panels  211  are extended out of the permanent magnet  212  to define a magnetic cavity between the extension portions. One side portion (right side portion) of the coil core  222  as the protrusion portion thereof is disposed within the magnetic cavity, wherein when the magnetic assembly is moved up-and-down, the protrusion portion of the coil core  222  can be moved within the magnetic cavity to contact with inner sides of the extension portions of the magnet conductive panels  211  in an alternating manner, so as to magnetize with the magnet conductive panels  211 . 
         [0053]    According to the preferred embodiment, during the movement of the magnet assembly  144  with respect to the coil assembly, the magnet conductive panels  1442  are magnetically attracted to the coil core  142  when the coil core  142  is facing toward the magnet conductive panels  1442 . It is appreciated that a gap can be formed between the magnet conductive panels  1442  and the coil core  142  as long as the coil core  142  is magnetized to generate the current. 
         [0054]    As shown in  FIG. 1 , three micro generators  14  are spacedly supported on the supporting panel  13 , wherein three switch panels  12  are pivotally coupled at the supporting panel  13  corresponding to the three micro generators  14  respectively. In particular, the three switch panels  12  are orderly coupled at the supporting panel  13  side-by-side to operate the three micro generators  14  respectively. In other words, the self-powered wireless switch  1  of the present invention provides a plurality of switch panels  12  in one switch unit, such that the switch panels  12  can be selectively actuated to operate the corresponding micro generators  14 , so as to control different electronic devices. The number of micro generators  14  can be selectively configured according to need of the electronic devices. Two or more micro generators  14  can be electrically linked to one control panel  15  via different circuits thereof. In other words, a number of diode rectifiers in the control panel  15  can be increased to form a power source partition of each micro generator  14 , such that each switch panel  12  is actuated to individually operate the corresponding micro generator  14  so as to prevent the interference between the micro generators  14 . 
         [0055]    As shown in  FIG. 1 , the self-powered wireless switch  1  further comprises an outer frame  11  formed in a ring shape to couple at the peripheral portions of the supporting panel  12  and the switch panels  12 . Therefore, the switch panels  12  can be securely coupled at the supporting panel  12  to protect the micro generators  14  and the control panel  15 . In order to install the self-powered wireless switch  1 , the outer frame  11  and the switch panel  12  can be detached from the supporting panel  12 , such that the supporting panel  12  can be affixed on a wall surface via screws. Then, the outer frame  11  and the switch panel  12  can be mounted on the supporting panel  12  to complete the wall installation of the present invention. Preferably, the supporting panel  12  and the switch panel  12  are formed in rectangular shape, wherein the outer frame  11  is also formed in rectangular shape. It is appreciated that the supporting panel  12  and the switch panel  12  can be formed in other shape, wherein the shape of the outer frame  11  is also formed correspondingly. 
         [0056]    It is worth mentioning that the switch panel  12  is an example to serve as an actuator to move the magnet assembly  144  up and down. Other actuators which can perform the same function can be used in the present invention. For example, the magnet assembly  144  can be directly moved manually. Since the micro generator  14  is the fundamental unit to be moved corresponding to the coil assembly, other actuators, including the switch panel  12 , can be modified to achieve the same result of the magnet assembly  144 . 
         [0057]    Accordingly, the supporting panel  13  of the self-powered wireless switch  1  can be coupled on a wood surface, a glass surface, marble surface, or tile surface via an attaching means such as glue. As it is mentioned above, the supporting panel  13  can be affixed on any surface via the screws. Therefore, the installation of the present invention does not require any pre-formed groove on the wall to minimize the noise and to prevent any pollution during conventional installation process. The operation of the present invention is the same as the conventional wire-type switch through the actuation of the switch panel, such that the present invention is considered as an environmental friendly product for residual and commercial use. 
         [0058]    Accordingly, the operational principle of the present invention is shown as follows: 
         [0059]    The coil core  142  sleeved in the magnetic coil  147  provides two functions of magnetization and change of magnet flux. As shown in  FIG. 7 , assuming that the lower magnet conductive panel  1442  has a S pole and the upper magnet conductive panel  1442  has a N pole. Initially, the side of the coil core  142  is magnetically attracted to the lower magnet conductive panel  1442 . Once the coil core  142  is magnetized, the S pole length of the lower magnet conductive panel  1442  will be further extended to the coil core  142 . In other words, the magnetic field will penetrate through the magnetic coil  147  and the line of magnetic force will form as N-S, i.e. through the coil core  142  from point A to point B (enter from the left side of the coil core  142  and exit at the right side of the coil core  142 ). As shown in  FIG. 8 , when the switch panel  12  is pivotally actuated to drive the magnet assembly  144  to move downward, the relative displacement between the magnet assembly  144  and the coil core  142  is changed. The coil core  142  is moved from the lower magnet conductive panel  1442  to the upper magnet conductive panel  1442 , such that the side of the coil core  142  is magnetically attracted to the upper magnet conductive panel  1442 . At the same time, the coil core  142  is magnetized that the N pole length of the upper magnet conductive panel  1442  will be further extended to the coil core  142 . As a result, the magnetic field will penetrate through the magnetic coil  147  and the line of magnetic force will form as N-S, i.e. through the coil core  142  from point B to point A (enter from the right side of the coil core  142  and exit at the left side of the coil core  142 ). 
         [0060]    As shown in  FIG. 11 , the line of magnetic force is changed between the magnet assembly and the coil core  222  during the movement of the magnet assembly. As a result, the line of magnet force  23  (the magnetic induction line) of the coil core  222  is changed oppositely. According to the Faraday&#39;s Law of Induction, when the induced current is generated by the magnetic coil, the voltage is generated correspondingly. It is worth mentioning that the alternating current generated by the coil will be transformed into a direct current through a rectifier, such that the DC current will guide to flow to the control panel as the power source thereof. The control panel  15  comprises a diode rectifier and a wireless signal generator, wherein the wire from the micro generator, the diode rectifier and the wireless signal generator are electrically linked together in order. In other words, the AC current generated by the magnetic coil  147  is guided to pass to the diode rectifier. The positive-negative poles of the current generated by the magnetic coil  147  at one actuation of the switch panel  12  are opposite to that of the current generated by the magnetic coil  147  at the previous actuation of the switch panel  12 . The diode rectifier will rectify the current from the magnetic coil  147  to ensure the proper current to pass to the wireless signal generator. Therefore, the wireless signal generator is powered up for generating the wireless control signal to control the desired electronic device. As shown in  FIG. 9 , the wireless control signal can be a coded control signal, such that when the electronic device receives the wireless control signal, a relay switch of the electronic device is activated to control the on-and-off of the electronic device. 
         [0061]    As shown in  FIG. 1 , the switch panel  12  can be pivotally moved at two ends thereof to move the magnetic assembly  144  up and down, so as to transform a mechanical energy into an electrical energy for supplying electrical power to the control panel. It forms the self-powered unit to generate the wireless control signal. The self-powered control switch  1  of the present invention is reliable comparing with the conventional wire-type control switch. It is safe to use because there is no power line electrically linked to the self-powered control switch  1  of the present invention. In addition, the self-powered control switch  1  of the present invention is a battery-less unit, such that no battery is required to be installed thereinto so as to minimize the operation cost of the self-powered control switch  1  of the present invention and to reduce the environmental pollution. It is worth mentioning that no electrical wiring is required for connecting the switch to the electronic device, such that the material cost, such as wires and PVC wire sleeves, can be significantly reduced. The installation process will also be simplified and shortened and the location of the control switch can be selectively adjusted. The user is able to switch on and off the electronic device through the actuation of the switch panel  12  as the actuation of the conventional switch. 
         [0062]    As shown in  FIGS. 12 and 13 , a self-powered control switch  2  according to a second embodiment illustrates an alternative mode of the first embodiment of the present invention, wherein the structural configuration of the self-powered control switch  2  is the same as that of the first embodiment, except the following: 
         [0063]    In the self-powered control switch  2 , the magnetic assembly  21  is affixed to the supporting panel  13 , wherein the magnetic assembly  21  is located at one side (right side) of the coil core  222  of the coil assembly  22 . The magnet conductive panels  211  are overlapped coupled at two sides of the permanent magnet  212  respectively, wherein the length of the permanent magnet  212  is shorter than the length of each of the magnet conductive panels  211 , such that two extension portions of the magnet conductive panels  211  are extended out of the permanent magnet  212  to define a magnetic cavity  213  between the extension portions. One side portion (right side portion) coil core  222  is disposed within the magnetic cavity  213 . The coil core  222  has a mid core body  2221  where the wire coil  221  are wound therearound, a first core arm  2223  (left core arm), and a second core arm  2222  (right core arm), wherein the first and second core arms  2223 ,  2222  are oppositely and alignedly extended from the mid core body  2221 . The first core arm  2223  is pivotally coupled at the supporting panel  13 . The second core arm  2222  is extended within the magnetic cavity  213 . The coil core  222  can be moved at the first core arm  2223  to contact the second core arm  2222  with the inner sides of the extension portions of the magnet conductive panels  211  in an alternating manner. The first core arm  2223  and the second core arm  2222  are integrally extended from the mid core body  2221  to form an integrated elongated body. It is appreciated that the mid core body  2221 , the first core arm  2223 , and the second core arm  2222  can be three individual components and coupled with each other. 
         [0064]    Accordingly, the wire coil  221  of the coil core  222  is driven to move when the first core arm  2223  of the coil core  222  is rotated about a pivot point thereof. Therefore, when the second core arm  2222  of the coil core  222  is moved upward to contact with the inner side of the extension portion of the upper magnet conductive panel  211  and is then moved downward to contact with the inner side of the extension portion of the lower magnet conductive panel  211 . As shown in  FIG. 11 , the line of magnet force  23  of the coil core  222  is changed, such that the coil  222  will generate the induced current as mentioned above.
