[Prior technology] A general switch is used to control a product between an on state and a closed state, such as a rotary switch for controlling the gas stove fire, a rotary switch for controlling the speed of a fan, etc. Control the opening and closing of the fire or fan motor, the size of the fire, the speed of the rotation speed and so on. As far as the current switches are concerned, the rotary switches are all mechanically used to control the opening or closing of the product. The related patented inventions are also designed to make mechanically turned rotary switches for these applications. 15 In FIG. 1, the rotary switch 1 includes a component 13. For the rotary switch 1 that generally controls the fan motor, a control member U, a positioning member 12, and an electrical control control member 11 are rotatably disposed on the positioning member 12. On the outer peripheral surface, there are—and 20 n ′ and—a rotating shaft 111 provided on the rotating shaft lu to drive the rotating shaft ⑴ to rotate, and has a plurality of card slots 113. The positioning member 12 has—the spring 121 that can be locked in the card slots U3 = Γ: Γ at the same time as the spring 121 and the control member η of the positioning member 12 so that when the spring = is connected, the component U becomes a predetermined electrical property. Horse == 5 M243774 state is at a predetermined speed. For example, when the rotating shaft 111 is controlled by the twist i U system 2 and the 5 * one is locked in the first slot 113, the electrical control member 13 is turned into an open state, and the fan can be controlled. The motor does not rotate because the circuit is not conducting; and when the rotary torque control 112 is turned to turn 1 and the shrapnel 121 is stuck in the -second slot, 'the electrical control member 13 is brought into a fully conductive state, it can be controlled. The fan motor rotates at the maximum speed; and when the shrapnel i2i card is held in the other row cut 113, the electrical state of the fan appears to be 10, so that the fan motor presents different predetermined speeds according to the preset electrical state. I urge the above-mentioned rotary switches that mechanically control products such as fan motors and gas stoves, although they can change various states to control the use of these products, however, these switches are contact-type. When used for a long time, they will produce Problems such as wear, fatigue contact of the shrapnel, etc. make the service life not as expected. At the same time, these rotary switches controlled by contact have poor water resistance. 15 Therefore, the above-mentioned mechanically-operated rotary switches still need to be improved. 'It has a longer life and a wider range of uses. [New content] 0 Therefore, the object of the present invention is to provide a non-contact non-contact switch rotation control device. Therefore, the rotation control device of the switch of the present invention can control the switch between an on state and a closed state. The rotation control device includes a plurality of magnetic induction elements, a rotation element, and a processing unit. The plurality of magnetic induction elements are arranged at intervals, and each magnetic induction element outputs an induction signal corresponding to a magnetic force change. 20 M243774 The rotating element is magnetic, and can change its position relative to the plurality of magnetic sensing elements. When the position of the rotating element is changed, a magnetic force change is generated, so that each magnetic sensing element outputs the sensing signal in response to the magnetic force change. The processing unit is electrically connected to the plurality of magnetic sensing elements to sense the plurality of sensing signals, and controls the switch to change states between the open state and the closed state according to the plurality of sensing signals. The function of the new model is to provide a rotary control device for the switch, which can control the change of the state of the switch in a non-contact manner to improve its service life and use. 10 [Embodiment] The foregoing and other technical contents, features, and effects of the present invention will be clearly understood in the following detailed description of a preferred embodiment with reference to the accompanying drawings. Referring to FIG. 2, a preferred embodiment 15 of the rotation control device of the novel switch is a switch (not shown) that can control, for example, a fan motor, so that the switch changes between an on state and an off state. Furthermore, the operating state of the fan motor is controlled. The rotation control device 2 includes a plurality of magnetic induction elements, a rotating element 22, and a processing unit 23. A plurality of magnetic induction 7C pieces 21 are arranged in a circle at equal intervals from each other, and the magnetic induction piece 21 is an output-induction signal corresponding to a magnetic force change. In this example, three Hall ICs are set on a dragon 211, and the knifes are arranged at regular intervals of 120 degrees, so that the three Hall ICs are respectively set at 12 o'clock, 4 o'clock, and 8 o'clock. The position in the direction of the clock indicates that the Hall IC, which uses the Hall effect as a characteristic, uses the principle of magnetoelectricity. When it senses the change in the magnetic 7 M243774 force, it can correspond to the change in output potential. The rotating element 22 has a disk body 221, a magnet disposed on the disk body 221, and a knob 223 capable of driving the disk body 221. After the disk body 221 is broken by the knob 223, it is set to set three huo. A central axis 24 of the disc 211 of the ear 1C is a rotation axis, and when the rotating element 22 rotates, the relative magnetic field formed by the magnet 221 to the three Hall IC will change, so that The magnetic force sensed by the ear 1C changes, so that each ear 1C outputs the potential change in response to the magnetic force change. 10 The processing unit 23 is a microcomputer, which is electrically connected to the three-holer IC and the switch of the fan motor, and can control the switch according to the sensed potential change of the three-hollow cymbal, thereby controlling the running state of the fan motor. When directly above ^, this Hall 1C is at a high potential, while the other 15 Hall 1C is at a -low potential; see FIG. 3, and when the knob 223 is turned == 12 clockwise. The degree is located at the other-set at four o'clock: when it is directly above the ear IC, it was originally set at o'clock. =: It changes from a high potential to a low potential, and when it is set-in the thunder position, it returns ^ its potential change It is a Hall IC which is placed at 8 o'clock in the direction of 8 o'clock from the rise of the low potential, and the second one can be sensed by this. The -potential change II is mainly located above the Hall IC in the 4 o'clock direction. Same as :: ===, the direction of rotation, the placed Hall IC Jit square rotates to be set above the 4 o'clock direction, and the purpose of rotation must be measured, and then according to this i. ¾ M243774 and other system results' ie The state of the switch can be controlled, thereby controlling the fan motor to turn on, off, or other speed changes, for example. Of course, the above-mentioned magnet 222 can be a permanent magnet with a magnetic force, or an electromagnet that generates magnetic force by turning on or off electricity. The type of the magnetic 5 sensing element 21 is not limited to Hall 1C, and the number is set at the same time. , The position is not limited to three, ring-shaped settings, etc., as long as it can sense the change of magnetic force or magnetic field, it will not be described here again. As can be seen from the above description, since the rotation control device 2 of the new switch uses non-contact sensing magnetic force change to detect the rotation angle and position after turning _ 10 movements, and then controls the state change of the switch, it can improve The conventional rotary switch 1 which uses the mechanical mechanism of contact with springs as a design principle has the disadvantages of contact wear and fatigue due to metal fatigue due to prolonged use, which prolongs the service life of the switch. The advantages of miniaturization and improved water resistance have indeed achieved the 15th purpose of this new model. However, the above are only the preferred embodiments of the new model, and the scope of the implementation of the new model cannot be limited by this, that is, the simple equivalent changes and modifications made according to the scope of the patent application of the new model and the content of the new specification. , All should still fall within the scope of this new patent. 20 [Brief description of the formula] Figure 1 is an exploded perspective view of a conventional rotary switch; Figure 2 is an exploded perspective view of a preferred embodiment of the rotary control device of the new switch, illustrating that a magnet is located on a The state above Hall 1C in the 12 o'clock direction; and 9 M243774 FIG. 3 is an exploded perspective view of a preferred embodiment of the rotation control device of the new switch, illustrating that a magnet is rotated to a position set at 4 o'clock The state above Hall 1C. 10 M243774 [Description of the main components of the diagram] 1 Rotary switch 21 Magnetic element 11 Control element 211 Disk 111 Rotary shaft 22 Rotating element 112 Rotating 221 Disc body 113 Slot 222 Magnet 12 Positioning element 223 Knob 121 Spring piece 23 Processing unit 13 Electrical control element 24 Central axis 2 Rotation control device
