A substantially annular blocking portion 33 is formed on the side wall of the through hole 31 along the circumferential direction of the through hole. The thickness of the blocking portion 33 is smaller than the thickness of the branching plate 3'', which can be resisted by the stopper projection 113 of the button 1G to prevent the limiting projection 113 from passing through the through hole 31. The gap (10) is further provided with a notch 331 corresponding to the limit protrusion 113. The width of the notch 331 is slightly larger than or equal to the width of the limiting protrusion S113 to ensure that the limiting protrusion 113 can pass through the notch 331. Referring to FIG. 4 and FIG. 5 together, the blocking portion is further provided with two long sliding grooves 333 which communicate with the corresponding notches 331 and extend circumferentially along the through holes 31. The sliding grooves 333 can be used for accommodating the hooks (4). The hook ιι 5 includes a 〇. The width of the sliding slot 333 is slightly larger than the thickness of the sliding portion 1151, and the depth of the sliding slot 333 is slightly smaller than the length of the sliding portion 1151. Therefore, when the hook 115 is inserted into the sliding slot 333, the sliding portion 1151 can be slid The groove 333 slides, and the hook portion 1153 can be located outside the sliding groove 333 and abut against the side wall of the support plate 30. [0014] The switch device 100 further includes a torsion spring 4〇. The torsion spring 4〇 is substantially cylindrical, and includes a spring. The body 41 and the first arm 43 and the second spring arm 45 at both ends of the spring body 41. The metal coil forming the spring body 41 has a certain gap in the axial direction, so that the spring body 41 can accumulate the torsional elastic potential energy on the one hand. On the other hand, the compression elastic potential energy can be accumulated by 098133104 Form No. Α0101 Page 5 / Total 18 Page 09820056704-0 201112288. The first spring arm 43 and the second arm 45 are approximately 90 degrees. Please refer to Figure 4 a side of the knob 11 opposite to the support plate 30 is further provided with a receiving portion The receiving groove (1) of the torsion spring 4G. The receiving groove 7 includes a first receiving portion 8 that is wound around the periphery of the push rod 13 and a second receiving portion 119 that extends from the first receiving portion 118 toward the circumferential surface of the rotary ring 1. The spring body 41 of the cyanine 40 can be received in the first receiving portion 118, and the first spring arm 43 can be received in the second receiving portion HQ. [0016] 098133104 The switch device 100 further includes a positioning plate 50 and two screws. 60. The positioning plate 5 is substantially disk-shaped, and a through hole 51 through which the push rod 13 of the button 10 passes is opened in the middle portion. A side of the positioning plate 50 opposite to the support plate 30 is further provided with a torsion spring for receiving part. The accommodating groove 53 of the 40 includes a first accommodating portion 531 surrounding the through hole 51 and a second accommodating portion 533 extending from the first accommodating portion 531 toward the circumferential surface of the positioning plate 50. The part of the spring body 41 can be received in the first accommodating portion 531, and the second spring arm 45 can be received in the second accommodating portion 533. The positioning plate 50. Two opposite brackets 55. Each of the brackets 55 is provided with a locking hole 551. The screw 60 can pass through the locking hole 551 to fix the positioning plate 50 to the support. The circuit board 70 can be of any shape and is provided with an elastic contact piece 71. When the elastic contact piece 71 is subjected to the pressure of the push rod 13 of the button 10, the elastic contact piece 71 is elastically deformed to make the circuit board The circuit on the 70 is turned on. After the pressure is released, the elastic contact piece 71 is restored to the original state and the circuit on the circuit board 7 is disconnected. When assembling, the torsion spring 40 first enters the receiving groove 53 of the positioning plate 50, and is twisted. The partial spring body 41 of the spring 40 is received in the first accommodating portion 531, and the second spring arm form number A0101 is 6th page/18 pages [0017] 201112288 45 is accommodated in the second accommodating portion 533. It is fixed to the support plate 30 by the two screws 6. The button 1 is mounted in the through hole 31 of the support plate 3 and the pusher 13 is placed in the torsion spring 4A. When the button 1 is installed, the second limiting protrusions 113 are respectively passed through the notches 331 of the support plate 30, and then the rotation hooks are rotated to make the hooks 115 on the limiting protrusions 113 enter the human domain plate 3 (). Chute 333. Under the action of the hook portion 1153 of the hook 115 and the support plate 3, the button 10 is relatively firmly mounted in the through hole 31. At this time, the partial spring body 41 of the torsion spring 4A is housed in the first housing portion 118, and the first spring arm 43 is housed in the second housing portion 119. Finally, the support plate 3 and the circuit board 7 are mounted together on the casing 2 of the main body 300, and the push rod 13 of the button 1 is opposed to the elastic contact 71 of the circuit board 70. When the standby switch device 100 is in the normal state, since the limit projection 113 of the knob is always in contact with the blocking portion 33 on the support plate 30, the pusher 13 is not moved when the knob 11 is directly pressed at this time. The elastic contact piece 71 is pressed. When it is necessary to turn off the switch device 100, the knob can be turned to a certain angle, so that the limit protrusion 113 of the knob 11 is at the position opposite to the notch 3 3 Ϊ > During this process, the first spring arm 43 rotates in the direction to elastically deform the torsion spring 40. At this time, since the width of the notch 331 is larger than the limiting protrusion 113, the pressing protrusion 按压 can pass the limiting protrusion 113 through the notch 331, so that the push rod 13 presses the elastic contact 71 of the circuit board 7 to make the circuit conductive. . At this time, the torsion spring 4 套 sleeved on the push rod 13 is in a --compressed state. After the pressure is removed, the torsion spring 40 first releases the compressive elastic force to cause the knob 11 to move backward, so that the pressure of the push rod 13 against the elastic contact piece 71 is released to cut the circuit. When the limiting protrusion 113 of the knob 11 is disengaged from the notch 331, the torsion spring 40 begins to release the elastic force of the twisting, so that the knob 1丨 reversely rotates and finally 098133104 Form No. A0101 Page 7 / 18 pages 0982056704-0 201112288 Reset [0024] [0024] [0024] [0024] The switching device of the embodiment of the present invention has not only the advantages of simple structure and convenience, etc., "Because the material needs to be rotated by the first limb, the angle can be used for it." Pressing, it can effectively prevent the operator from accidentally touching == causes the switch device to be turned off by mistake, and has better prevention of misoperation. The pits on the knob 11 can also be omitted. The limit protrusions 11 3 The number may also be - or more than two, and the number of notches 331 is also corresponding. The second spring arm 45 of the Danxiang torsion spring 40 is directly fixed to the support plate 3, and the positioning plate 5 can also be omitted. The side wall of the through hole 31 of the supporting plate 3 can be provided with a receiving groove for accommodating the second spring arm π of the torsion spring 40. If the rest of the hand 11 is restored, the wire is recorded, i. When the function is reset, the torsion spring 40 can also be omitted. Further, the switch device 1 provided by the present invention is also It can be applied to fields other than computer mainframe 300, such as machine tool electric control box, etc. In summary, this issue (4) has met the requirements of the invention patent, and patented the patent towel 4.
