BEST MODE FOR CARRYING OUT THE INVENTION

In view of the structural composition of the present invention, and the functions and advantages that can be produced, in conjunction with the drawings, a preferred embodiment of the present invention will be described in detail below.

Referring to FIG. 1A, a switch structure of the contact action of the present invention is shown, which includes:

A magnetic control switch 10 comprising:

The switch sleeve 11 is a conductive sleeve 60 having a tubular shape and distinguishing the upper joint end 111 and the lower joint end 112 by a stepped outer shape, and has an upper opening and a lower opening respectively; wherein the switch sleeve 11 has an internal portion An abutting flange 113 having a smaller opening size than the upper opening.

An insulating sleeve 12 is disposed in the switch sleeve 11 for electrically isolating between components inside and outside the insulating sleeve 12; wherein the switch sleeve 11 is made of plastic material.

a magnet 13 is a ring having a central hole, is located in the insulating sleeve 12, and is abutted against the abutting flange 113 through the insulating sleeve 12; thus, the magnet 13 is not removed by the switch sleeve 11 The opening fell out.

A T-axis 14 has a long axis 141 and a head 142. The long axis 141 passes through the central hole and extends the front end of the long axis 141 beyond the lower opening by a specific distance. The head 142 is larger in size than the central hole. Dimensions in which the T-axis 14 is a conductive material that is magnetizable and adsorbed by the magnet 13.

a conductive package cover 15 having a cup shape with an opening and being electrically conductive, is located in the insulating sleeve 12; the conductive package cover 15 covers the upper opening of the switch sleeve 11 with a cup bottom; and the conductive package cover 15 The opening is placed against the magnet 13, wherein the insulation between the conductive package cover 15 and the magnet 13 is rendered inoperable by an insulating means. The conductive package cover 15 is made of a metal material.

The insulating method uses a plastic insulating gasket located between the opening of the conductive package cover 15 and the magnet 13 and a non-conductive permanent magnet 13 as a natural insulator. The purpose is to isolate the electrical conduction between the conductive package cover 15 and the magnet 13. In the embodiment of the present invention, the non-conductive permanent magnet 13 will be described.

Therefore, the area between the cup bottom of the conductive package cover 15 and the magnet 13 allows the head 142 of the T-shaped shaft 14 to move inside. Therefore, the movement stroke of the head portion 142 of the T-shaped shaft 14 is restricted by the magnet 13 and the conductive package cover 15, and the movement stroke of the end of the long shaft 141 is indirectly restricted.

An electronic component 20, an electrode (such as a positive electrode) of the electronic component 20 is connected to the front end of the long axis 141 of the T-shaped shaft 14, and the other electrode (such as the negative electrode) of the electronic component 20 is directly and indirectly (such as using a wire). One way is to electrically connect the switch sleeve 11. The electronic component 20 is preferably a circuit board, an electronic component 20 having a light emitting function, a vibrator or the like.

Hereinafter, the embodiment will be described with reference to the drawings, in which the thick black line segments indicated are wires. As shown in FIG. 1A, when the T-axis 14 has no external force contact, the head 142 of the T-axis 14 is attracted to the magnet 13 due to the magnetic force, so that the power circuit of the electronic component 20 cannot be guided. through. As shown in FIG. 1B, when the external force 80 received by the T-axis 14 is greater than the magnetic force, the head 142 can be brought into contact with the conductive package cover 15 away from the upward opening of the magnet 13 when the T-axis is When the conductive package cover 15 is in contact with the conductive package cover 15, the power of the power source 30 is sequentially composed of an electrode of the power source 30, the conductive package cover 15, the T-axis 14, the electronic component 20, the switch sleeve 11, and the other electrode of the power source 30. A power loop is formed to enable the electronic component 20 to operate. However, when the external force disappears, the head 142 of the T-axis 14 is again attracted back to the magnet 13, as shown in Fig. 1A, thus forming an automatic open circuit switch.

The magnetic control switch 10 of the utility model is used for a light-emitting pen, a massage pen, a capacitance pen and a heating pen. 2A and 2B are the same as the first embodiment of the present invention, and the same components as those in the first embodiment are denoted by the same reference numerals, and their functions and connection relationships are not described herein again.
