The sheet is not located in the -5- 1235396 same-plane 'and the end of the power guide sheet is in contact with the conductive ring of the swivel. [Embodiment] In order to explain the structure and characteristics of the present invention in detail, the following 5 preferred embodiments are described in conjunction with the drawings as follows, where the first diagram is a perspective view of a preferred embodiment of the present invention, The second figure is an exploded perspective view of the preferred embodiment of the present invention; the second figure is a schematic view of the top view structure with the top cover removed according to the preferred embodiment of the present invention; Sectional view. Referring to the drawings, a rotary switch according to the present invention includes an upper case 10 ′ (see the second figure), a shaft hole U is provided in the center, and a locking hole 12 is provided on both sides for Lock the switch on a predetermined object. The lower case 20, see the first and second figures, has a space 15 for receiving 21 'and is also provided with a shaft hole 22 opposite to the shaft hole 11 of the upper case 10. The upper case 10 and the lower The housings 20 can be mated with each other. A swivel body 30, see the second and fourth figures, is accommodated in the accommodating space 21 of the lower case 20, and has a rotating shaft (31) (32) at its top and bottom ends respectively. In the shaft holes (11) (22) of the upper and lower casings (10) (20). There are three positioning portions 35 on the side of the swivel body 30, and a conductive ring 33 is provided on the bottom side. The outer diameter of the conductive ring 33 is larger than that of the swivel body 30, so that the side of the swivel body 30 surrounds the conductive ring 33. The conductive ring 33 extends with a conductive strip 34 provided on the side of the swivel body 30. Please refer to the second and third figures. The three positioning portions 35 and the conductive strip 34 are spaced apart from each other on the side of the swivel body 30. The conductive ring 33 The positioning part 6- 1235396 35 that matches the turning body 30 is provided with three notches 331 correspondingly. One or more conductive sheets, as shown in the second and third figures, are disposed in the lower case 20 and are located around the swivel body 30. Each of the conductive sheets has one end and the side of the swivel body 30, However, it is not in contact with the conductive ring 33. In the fifth embodiment, the lower casing 20 is provided with four recessed grooves (23) (24) (25) (26) around the swivel body 30, of which three recessed grooves (23) (24) (25) A cushion member 27 is provided therein, which is composed of three supporting columns, and three conductive plates (42) (43) are arranged in the three recessed grooves (23) (24) (25) and are located on the cushion member 27, and It is located above each of the recesses (23), (24), (25). Each of the conductive pieces 40 is provided with a contact portion 44 against the side of the rotating body 30. When the rotating body 30 rotates to a predetermined angle, one of the conductive pieces 41 can contact the conductive strip 34, and the other two are conductive. The pieces (42) (43) can be positioned by engaging the contact portions 44 with each of the positioning portions 35. A power supply guide 50, as shown in FIGS. 2 to 4, is disposed in the lower case 20, and is placed in an embedded slot 26 without a cushion member, and is located below 15 in the embedded slot 26. The guide sheet 50 and the conductive sheets (41), (42), (43) are not located on the same plane. The power guide 50-end is in contact with the conductive ring 33 of the rotating body 30. The upper case 10 is provided with a protrusion 13 opposite to the power guide 50. When the upper and lower cases (10) (20) are mated, the protrusion 13 abuts the power guide 50 against the lower case. The bottom surface of the body 20. In this embodiment, a contact portion 5b is also provided at one end of the power guide piece 5020. At the same time as the conductive ring 33 is in contact with the conductive ring 33, it can be locked with the positioning portions 35 at a predetermined angle of the swivel 30. Fixed position. Referring to the second figure, the lower casing 20 is provided with a perforation 28 on a peripheral wall of the four recessed grooves for a power supply line (not shown) to pass through and be connected to each of the conductive pieces (41) (42) (43). ) 与 该 动力 导 片 50。 With the power guide 50. Because the power guide 50 and the conductive -7-1235396 pieces (41) (42) (43) are not located on the same plane, the perforations 28 corresponding to the lower casing 20 are not located on the same plane. , When you connect the line, you can clearly determine the plug position of the power cord. In the present invention, the conductive sheet and the power supply guide are staggered and are not located on the same plane. By using this type of space, the power supply guide sheet is elastically connected to the conductive ring with the conductive contact portion, thereby reducing the rotation of the user in surface contact. The consumption of grinding shells caused by friction can indeed reduce the defective rate of the product. In addition, the scope of the present invention is not limited to the embodiments described above. The conductive sheet can be located on the lower side of the slot and the power guide sheet can be placed on the upper side, or the conductive sheet can be arranged in a step-like arrangement. Not on the same plane. The purpose of the invention can also be achieved. The invention can increase or decrease the number of conductive sheets according to the needs of the use. In addition, it can also arrange more than one power supply guide sheet (not on the same :, Surface), and with an equal number of conductive rings (aligned with the corresponding power supply guide, etc., each square switch can be re-selected / opened, and the same-seeking structure only should be included in the present invention. 1235396 [Brief description of the drawings] The first figure is a perspective view of a preferred embodiment of the present invention.
