The following describes the assembly process of the multidirectional switch device 100 of the present invention. Referring to the second and fifth figures, the operating body 3 is first placed on the protruding portion 15 of the chassis 1, and then the elastic member 2 is mounted in the receiving space 10 of the chassis 1. The holding portion 22 is held in the holding groove 13, and the pushing portions 23 of the four elastic members 2 are uniformly distributed around the large diameter portion 31 and abut against the side edge 311 of the large diameter portion 31; The circuit board 4 is mounted above the chassis 1 and the positioning hole 41 is corresponding to the positioning hole 14 , and the operating portion 32 is passed through the opening 40 , and the sliding blocks 6 on which the movable terminal 5 is mounted are orthogonally stacked and then sleeved on the chassis 4 .

Finally, the dustproof plate 8 and the rocking plate 9 are attached. . The operation principle of the multidirectional switch device of the present invention will be described in detail below. Please refer to the second to fifth figures. When the jog dial 9 is operated (the operation body 3 is directly operated when the dust guard 8 and the rocker 9 are not mounted) When the 360-degree radial direction is actuated, the operating portion 32 of the operating body 3 will drive the sliding block 6 to slide in the corresponding direction, while the side edge 311 of the large-diameter portion 31 of the operating body 3 will push the elastic member 2 toward the corresponding The directional movement forces the curved base portion 21 of the elastic member 2 to elastically deform and accumulates an elastic restoring force (the direction of the elastic restoring force is opposite to the direction in which the large-diameter portion 31 urges the elastic member 2), and the movable terminal 5 is in the sliding block. The driving of the 6 is offset from the initial position and is in contact with the specific position of the circuit board 4. The circuit board 4 will feedback different electrical signals according to different resistance values of different positions between the circuit circuits to characterize the operation (4) of the same position; when the operating body 3 is After the external force is removed, the elastic element 2 that has undergone elastic deformation is recovered by the elastic restoring force accumulated by the elastic member 2, and the elastic form number is restored to the initial state, and the elastic form number is Α0101, page 7 / total 17 ' * 1002001330-0 201230 108 The element 2 is forced to return to the initial state of the central position by the pushing portion 23 during the returning to the initial state, and the pushing portion 23 is returned to the abutting wall 151 of the protruding portion 15 of the chassis 1 In the initial position, the arrangement of the projections 15 can prevent the elastic member 2 from deviating from the initial position after returning. The preferred embodiment of the present invention is that the side edge 311 of the operating body 3 is held by the four elastic members 2, and when the operating body 3 moves in the direction perpendicular to the pushing portion 23 of the elastic member 2, an elastic member 2 is forced to be generated. The displacement simultaneously drives the movable terminal 5 on the sliding block 6 to change the position of the contact point of the movable terminal 5 and the circuit board 4 to trigger the change of the resistance value between the corresponding lines. When the operating body 3 does not move in the direction, the two will be forced at the same time. The displacement of the elastic element 2 simultaneously drives the movable terminal 5 on the two sliding blocks 6 to change the position of the contact point of the movable terminal 5 and the circuit board 4 and trigger the change of the resistance value between the corresponding lines. [0019] The multidirectional switch device 100 of the present invention achieves automatic resetting of the operating body 3 by the arrangement of the elastic member 2 held by the chassis 1 and abutting against the operating body 3, and has a simple structure and is easy to assemble.
