CLAIM S

1. A driving member for a push-button switch, comprising: a body configured to be adaptable to drive said push-button switch to act; and an elastic reset portion extending from said body, said elastic reset portion having elasticity, wherein said body has a first side and a second side opposite to each other, and a first end and a second end opposite to each other, said first end is located at one end of said first side and said second side, and said second end is located at the other end of said first side and said second side, and wherein driving surfaces are provided on the first end and the second end, and are configured to switch a state of the push button switch by moving to two different operating positions to drive an actuation mechanism of the push button switch in different directions.

2. The driving member according to claim 1, wherein said driving member is configured so that when said elastic reset portion is fixed, said body is able to linearly move in the connection direction of said first end and said second end from an initial position relative to said elastic reset portion under the action of a force applied onto said driving surfaces; and when the force applied onto said driving surfaces is released, said elastic reset portion applies an elastic resetting force to said body to make said body reset to said initial position.

3. The driving member according to claim 2, wherein said elastic reset portion comprises elastic legs extending from the first side and/or the second side of said body, respectively, and said driving member is configured so that when said elastic legs are fixed, said body is able to linearly move in the connection direction of said first end and said second end from an initial position relative to said elastic legs under the action of a force applied onto said driving surfaces; and when the force applied onto said driving surfaces is released, said elastic legs apply an elastic resetting force to said body to make said body reset to said initial position.

4. The driving member according to any one of claims 2 or 3, wherein middle portions of said first side and/or said second side are recessed toward the center of said body to form recessed areas, or protrude toward a direction away from the center of said body to form protrusion areas, and said elastic legs extend toward the outside of said body from said recessed areas or extend toward the center of said body from said protrusion areas.

5. The driving member according to any one of claims 3 or 4, wherein said elastic legs have a bend in a direction perpendicular to a first major surface and a second major surface, and/or said recessed areas or said protrusion areas have a bend in a direction perpendicular to said first major surface and said second major surface.

6. The driving member according to any one of claims 2 to 5, wherein enlarged end heads are formed at the free ends of said elastic legs, the side surfaces of said end heads having arc-shaped surfaces.

7. The driving member according to any one of claims 2 to 6, wherein said first side, said second side, said first end and said second end of said body are interconnected to form a closed loop, and a hollow space is formed inside the loop.

8. The driving member according to any one of claims 2 or 3, wherein said first side, said second side, said first end and said second end of said body are interconnected to form a closed loop, and a hollow space is formed inside the loop; and middle portions of said first side and/or said second side are recessed toward the center of said body to form recessed areas, or protrude toward a direction away from the center of said body to form protrusion areas, said recessed areas or said protrusion areas having elasticity so as to be at least one part of said elastic reset portion.

9. The driving member according to any one of claims 2 to 8, wherein said driving member has a first major surface and a second major surface opposite to each other that are perpendicular to said first side and said second side, one of the driving surfaces being formed on said first major surface and tilting or bending with respect to said first major surface, for converting a force received by it into a component force in the connection direction of said first end and said second end.

10. The driving member according to claim 9, wherein there is a guide block on said second major surface to guide a linear movement of said driving member.

11. The driving member according to any one of claims 1 to 10, wherein said driving member is formed of a material having elasticity.

12. A push-button switch, comprising: the driving member according to any one of claims 1 to 11.

13. The push-button switch of claim 12, further comprising: a button; said actuating mechanism; and a conductive bridge that is coupled to said actuating mechanism, and is able to be driven by said actuating mechanism to deflect in two directions opposite to each other, to contact with or detach from a stationary contact; wherein said driving member is mounted in said button for driving said actuating mechanism to act.

14. The push-button switch of claim 13, wherein a portion of said elastic reset portion of said driving member is constrained by said button, so that the movement of said free end in a direction perpendicular to the extending direction of said elastic reset portion is limited; and said driving member is configured so that: in response to said button being pressed, a driving surface at one end of said driving member presses one side of said actuating mechanism to make said actuating mechanism swing, so that said actuating mechanism drives said conductive bridge to deflect in a first direction to contact with or detach from a stationary contact, and at the same time, a side of said actuating mechanism pressed by said driving member drives the body of said driving member to move linearly from the initial position against the elastic resetting force of said elastic reset portion, so that an end of said driving member pressing said actuating mechanism is away from a swing center of said actuating mechanism; and in response to said button being released, the elastic resetting force of said elastic reset portion drives the body of said driving member to move linearly and reset to said initial position.

15. The push-button switch according to claim 14, wherein both ends of the swing center of said actuating mechanism have force receiving surfaces, respectively, and said force receiving surfaces match with the driving surfaces on corresponding ends of said driving member, respectively; and after a driving surface at one end of said driving member presses a side of said actuating mechanism so that the body of said driving member is driven by said actuating mechanism to linearly move, a driving surface at the other end of said driving member is moved to a position displaced from the force receiving surfaces on the corresponding ends of said actuating mechanism.

16. The push-button switch of claim 14 or 15, wherein a fixing groove is provided inside said button, and a portion of said elastic reset portion of said driving member is accommodated in said fixing groove, so that the movement of said free end in a direction perpendicular to the extending direction of said elastic reset portion is limited.

17. The push-button switch according to claim 16, wherein there are two sets of positioning tabs inside said button, said fixing groove being formed in the middle of each set of positioning tabs, and said two sets of positioning tabs also support the first side and the second side of the body of said driving member, respectively.

18. The push-button switch according to any one of claims 13 to 17, wherein there is a guide groove inside said button and there is a guide block on the body of said driving member, said guide block being located in said guide groove to guide the body of said driving member to linearly move along said guide groove.
