Description of the Invention: [Technical Field] The present invention relates to a switch, and more particularly to an inductive device for use in an electronic product. [Prior Art] Referring to Fig. 1, a conventional ball switch ι00 includes a sleeve 1〇1, a ball 102, four terminals 1 〇3, and a plug block 1 〇4. Referring to Figures 1 and 2, the assembly is such that the ball 1〇2 is put into the sleeve 101, and the plug block 104 is sealed at the opening of the sleeve 101 to block the ball 102. The terminals 1 〇 3 are placed at appropriate depths of the four through holes 1041 of the plug block 104 so that the terminals 103 are tightly inserted into the through holes 1041. The ball switch 100 of the T-type has a purpose of ensuring conduction by contacting a tapered portion 101 at the top end of the four terminals 1〇3, but the structure of the terminal 103 of the straight column type is inserted into the ball When the sleeve is 1〇1, it is suspended in the air. Therefore, the accuracy of the operation of the fixture must be very high, so that the length of the insertion into the sleeve is the same, so that the switch can be operated. As long as there is a slight difference between the height and the low, the function is lost. In addition, the terminal 1〇3 with the same outer diameter is easily pulled by the external force and is displaced, resulting in poor stability after bonding, so it is necessary to seek a solution. Referring to FIG. 3, the above-mentioned ball switch 1 can be used on a circuit board 105 in the upright mounting manner of FIG. 2, and the sleeve 1 can be folded by folding the terminals 103. An angle angle 0 is formed between the circuit board and the circuit board 1〇5 for applying to the normally closed state. In the normal state, the ball 5 1297160 102 does not contact the terminals i〇3, so that the ball switch 1〇〇 In the 〇FF state, when the external ball vibrates, the ball 1〇2 instantaneously jumps and simultaneously contacts the terminals 103, the ball switch 1〇〇 can be turned into the 〇N state; Changing the use angle of the ball switch 1 符合 to conform to different electronic products or different demand angles, but when the ball switch 100 is mounted on the circuit substrate 1 〇 5, due to the housing ιοί and the circuit Between the substrates 105, φ is suspended by the terminals 1 〇 3, and when the housing ι 1 is not stably supported, it is easily affected by an external force to change the angle at which the terminals 1 〇 3 have been previously solidified. So, will cause the ball switch 100 lost its function. SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide an inductive device in which the terminal is stably positioned, the conduction effect is good, and the sensing is sensitive. Another object of the present invention is to provide an induction device that is easy to manufacture and consistent in quality. Thus, the sensing device of the present invention comprises a housing, a first terminal unit, a second terminal unit, a copper bead, and an outer cover. The outer casing has a base wall and a circumferential wall extending outwardly from the base wall and defining a cavity and an opening. The first terminal unit is disposed in the housing of the outer casing and has two first terminals spaced apart from each other, and the first terminals have a main body portion disposed at a valley of the outer casing, and one end of the main body portion Extending outwardly to extend through a terminal portion of the outside of the child's valley, and an extension extending horizontally outward from an inner side of the body portion - the extension having - self-adjacent to one of the body portions 6 1297160 The slanted top surface with the end increasing toward the outer end. The second terminal unit is disposed in the housing of the outer casing and spaced apart from the second terminal unit, the second terminal unit has two mutually spaced second terminals, and the second terminal has a second housing disposed thereon. The main body of the chamber, -η 收, is bundled from one end of the main body portion and extends out of the terminal portion of the outer casing of the outer casing.
