Shaft core 300 is towards the open hollow structure in the side of base 220, in side of the shaft core 300 away from base 220 It is provided with the blind hole 305 for installing button.

The one end of guide pillar 303 away from guide pin bushing 2211 is fixedly connected on the medial center of shaft core 300, and guide pin bushing 2211 is remote to lead One end of post 303 is fixedly connected on axle bed 200 towards the center of the inner wall section of through hole 213；

Or the one end of guide pin bushing 2211 away from guide pillar 303 is fixedly connected on the medial center of shaft core 300, guide pillar 303 is remote One end of guide pin bushing 2211 is fixedly connected on axle bed 200 towards the center of the inner wall section of through hole 213.

In the present embodiment, as shown in Figure 7 to 9, guide pillar 303 is integrally disposed upon the medial center of shaft core 300, guide pin bushing 2211 The side wall of body 221 of base 220 is integrally disposed upon towards the center of the side of opening.

Spring 400 is set on guide frame, and one end of spring 400 pushes against the medial center of shaft core 300, spring 400 The other end push against base 220 the side wall of body 221 towards opening side center, i.e., spring 400 the other end push against axle Inner wall section of the seat 200 towards through hole 213.

As shown in Fig. 3, Fig. 8 to Figure 10, shaft core 300 has outwardly feel in the side away from optoelectronic switch 600 Block 302 is touched, axle bed 200 offers the second chute for touching block 302 for feel and stretching out in the side wall away from optoelectronic switch 600 224 (the second chute 224 penetrates upper lid 210 and base 220 simultaneously).Feel touches block 302 in shaft core 300 perpendicular to circuit board 100 moved during slided in the second chute 224.

As shown in figs, in the body 221 of base 220 side wall relative with the side wall where the first chute 223 Outside is provided with the installation portion 2214 of torsion spring 500, and torsion spring 500 is provided with the installation portion 2214 of torsion spring 500.One end of torsion spring 500 Be relatively fixed positioned at the inside of 500 installation portion of torsion spring 2214 and the formation of base 220, the other end extend to be formed with shaft core 300 perpendicular to The vertical stretch section 501 of the direction of motion of circuit board 100, can be stirred when shaft core 300 is moved perpendicular to circuit board 100 The stretch section 501 of torsion spring 500.

Axle bed 200 also sets up stopper section 2215 and protuberance 2216 on the lateral wall away from optoelectronic switch 600.Stopper section 2215 and protuberance 2216 be arranged at intervals successively to the direction at the back side along the front of circuit board 100, the stretch section 501 of torsion spring 500 Between stopper section 2215 and protuberance 2216.

Transport in the back side to positive direction of the stretch section 501 that stopper section 2215 is used to limit torsion spring 500 along circuit board 100 It is dynamic.Protuberance 2216 is used for during being moved in direction of the shaft core 300 along front to the back side of circuit board 100, makes torsion spring 500 Stretch section 501 depart from feel and touch the back side to positive direction of the block 302 along circuit board 100 and move return.

Have respectively in direction of the shaft core 300 along front to the back side of circuit board 100 as shown in figure 9, feel touches block 302 Contact down the face of stirring 3022 when motion and reverse return with the stretch section 501 of torsion spring 500 and above stir face 3021.On stir Face 3022 is stirred with and is set gradually along front to the direction at the back side of circuit board 100 in face 3021.Under stir face 3022 with upper group Dynamic face 3021 connects and mutually at an acute angle at one end, and arc transition use in joint, above stirs face 3021 to stir face under remote 3022 one end is to the inclined inclined-plane in inner side of axle bed 200.

Protuberance 2216 have when shaft core 300 is moved along the front of circuit board 100 to the direction at the back side with torsion spring 500 The working face that stretch section 501 contacts, working face are identical with above stirring the incline direction of face 3021.

When direction of the shaft core 300 along front to the back side of circuit board 100 is moved, feel is touched block 302 and set aside by it Dynamic face 3022 contacts with the stretch section 501 of torsion spring 500 and drives front of the stretch section 501 of torsion spring 500 along circuit board 100 extremely The direction motion at the back side, when the stretch section 501 of torsion spring 500 moves to the contact of incline plane with protuberance 2216, protuberance 2216 Inclined-plane the stretch section 501 of torsion spring 500 is gradually pushed up to lateral direction to axle bed 200, until the stretch section 501 of torsion spring 500 is de- Touched from feel after stirring face 3022 under block 302, the stretch section 501 of torsion spring 500 is along circuit board 100 under its own resilient Return is moved in the back side to positive direction, sends sound.

When return is moved at the back side of the shaft core 300 along circuit board 100 to positive direction, feel touches block 302 and passes through it On stir face 3021 and contacted with the stretch section 501 of torsion spring 500 and gradually push up the stretch section 501 of torsion spring 500 to axle bed 200 Lateral direction, until torsion spring 500 stretch section 501 depart from feel touch block 302 on stir face 3021 after, the bullet of torsion spring 500 Property section 501 be under its own resilient axle bed 200 interior side direction return, send sound.
