Specifically, the elastic member 100 provides the toggle member 90 with an elastic force abutting against the rocker 80.

The switching process of the switch structure in the present embodiment between the off state and the on state is specifically explained below.

In the state switching process of the switch structure, the connecting rod 30 can limit and plan the movement track of the transition piece 20, so that a virtual pendulum shaft can be created for the transition piece 20, and the virtual pendulum shaft can break through the space limitation and be arranged outside the entity of the switch structure, so that the distance between the pendulum shaft of the transition piece 20 and the pendulum shaft of the rocker 80 is increased, the purpose of reducing the swinging angle of the transition piece 20 is achieved, and the swinging angle of the button panel 40 is further reduced.

As shown in fig. 7, the first rotating shaft 23 on the left side is higher than the first rotating shaft 23 on the right side, that is, the transition piece 20 is inclined to the right, and the rocker 80 is pushed by the pushing piece 90 to be abutted to the connection terminal 60 on the left side for conduction, and at this time, the switch structure is in an off state. When the switch structure is switched from the off state to the on state, the user presses the left side of the button panel 40, the button panel 40 rotates counterclockwise, and the contact surface 41 on the left side of the button panel 40 presses the first rotating shaft 23 on the left side of the transition piece 20, so that the transition piece 20 is driven to swing counterclockwise around the virtual swing axis, and meanwhile, the connecting rod 30 on the left side rotates clockwise and downward. At the same time, the first rotation shaft 23 on the right rotates counterclockwise and upward, while the link 30 on the right rotates clockwise and upward. As shown in fig. 8, as the transition piece 20 swings counterclockwise about the virtual swing axis, the state of the first rotating shafts 23 on the left and right sides changes to the state that the first rotating shaft 23 on the left side is lower than the first rotating shaft 23 on the right side, in the process, the toggle piece 90 dials the rocker 80 to the connecting terminal 60 on the right side, so that the rocker 80 is disconnected from being in contact with the connecting terminal 60 on the left side and is in contact with the connecting terminal 60 on the right side, and the switch structure is switched from the off state to the on state.

In the present embodiment, the length of the connecting rod 30 is a, the length of the bridge 21 is b, and the length of the second rotating shaft 11 is c, so that the distance between the two second rotating shafts 11 needs to satisfy 2a+b > c. This ensures that the connecting rod 30 always has an angle with the bridge 21, so that the transition piece 20 always remains inclined to one side.

Specifically, the principle that the transition piece 20 in the present embodiment can reduce the swing angle will be explained in detail below.

As shown in fig. 9, in the prior art, x is the stroke of the toggle member 90; alpha is the rotation angle of the toggle member 90, i.e. the swing angle of the transition member 20; d is the distance between the pendulum axis of rocker 80 and the pendulum axis of transition piece 20. As shown in fig. 10, in the present embodiment, x is the stroke of the toggle member 90, and β is the rotation angle of the toggle member 90, that is, the swing angle of the transition member 20; (d+d1) is the distance between the pendulum axis of rocker 80 and the virtual pendulum axis of transition piece 20. On the premise that the stroke x of the toggle member 90 is unchanged, the swing angle α=arctan (x/d) of the transition member 20 in the prior art, and correspondingly, the swing angle β=arctan [ x/(d+d1) ] of the transition member 20 in the present embodiment, it is obvious that β < α. Therefore, with the above arrangement, the swing angle of the transition piece 20 in the present embodiment becomes small, and thus the swing angle of the button panel 40 is reduced.

From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: the switch structure comprises a fixing frame 10, a switch assembly and a button panel 40, wherein the switch assembly comprises a transition piece 20 and a connecting rod 30, the connecting rod 30 is at least one, the connecting rod 30 is respectively and rotatably connected with the transition piece 20 and the fixing frame 10 or is in lap joint, the button panel 40 is rotatably connected with the fixing frame 10 and is in butt joint with the transition piece 20, the button panel 40 drives the transition piece 20 to swing so that the switch structure is switched between an off state and an on state, a virtual pendulum shaft can be created for the transition piece 20 through the arrangement, the virtual pendulum shaft can break through a space and is limited outside an entity of the switch structure, the distance between a rotating shaft of the transition piece 20 and the pendulum shaft of the rocker 80 is further increased, the purpose of reducing the swing angle of the transition piece 20 is achieved, the swing angle of the button panel 40 is further reduced, a user can easily press the button panel 40 without using larger force when using the switch structure, the use comfort of the switch structure is improved, and in addition, the thickness of the switch structure is correspondingly thinned due to the reduction of the swing angle of the button panel 40, and the aesthetic property of the switch structure is improved.
