Abstract

A switch structure connectable with both bare lead and flat-head terminal lead. The switch structure includes a main body formed with at least one cavity. A retainer member and a conductive metal member are arranged in the cavity for pressing the terminal lead into electrical connection with the conductive metal member. A reciprocally movable carrier body is assembled with the retainer member. The carrier body has an arm assembled with an elastic member. A restriction body is disposed in the cavity. The restriction body is formed with a chamber for receiving the arm and the elastic member of the carrier body. The restriction body restricts the moving direction or distance of the carrier body to increase the structural strength of the switch structure and enhance the lead locking ability of the switch structure.

First claim

What is claimed is:

1. A switch structure comprising:
a main body, the main body being formed with at least one cavity and at least one perforation corresponding to the cavity, a retainer member and a conductive metal member being arranged in the cavity, the conductive metal member being formed with a wall and a notch formed on the wall;
a reciprocally movable carrier body assembled with the retainer member, the carrier body being formed with a carrier face and a neck section protruding from the carrier face, the neck section having a rear end, the rear end of the neck section having an arm assembled with an elastic member, whereby the neck section is movable within the notch; and
a restriction body disposed in the cavity, the restriction body being formed with a chamber for receiving the arm and the elastic member of the carrier body.

2. The switch structure as claimed in claim 1 , wherein the conductive metal member includes a plane and a pivot hole formed on the plane, the conductive metal member having a contact pin for electrically contacting a conductive plate disposed in the main body.

3. The switch structure as claimed in claim 2 , wherein the wall is normal to the plane.

4. The switch structure as claimed in claim 2 , wherein the carrier face being formed with a hole corresponding to the pivot hole of the conductive metal member for assembling with the retainer member.

5. The switch structure as claimed in claim 4 , wherein a subsidiary arm is formed at the rear end of the neck section, the arm and the subsidiary arm being in parallel to each other and normal to the carrier face, the arm having a length shorter than a length of the subsidiary arm.

6. The switch structure as claimed in claim 1 , wherein the carrier body is further formed with a subsidiary arm in parallel to the arm.

7. The switch structure as claimed in claim 2 , wherein the carrier body is further formed with a subsidiary arm in parallel to the arm.

8. The switch structure as claimed in claim 1 , wherein the elastic member has the form of a spring.

9. The switch structure as claimed in claim 1 , wherein the cavity is formed with a dent in which the restriction body is disposed.

10. The switch structure as claimed in claim 1 , wherein the restriction body is integrally formed with the main body.

11. The switch structure as claimed in claim 1 , wherein the restriction body is formed with a chamber and a guide channel, the chamber serving to receive the arm and the elastic member of the carrier body.

12. The switch structure as claimed in claim 5 , wherein the restriction body is formed with a chamber and a guide channel, the chamber serving to receive the arm and the elastic member of the carrier body, the guide channel serving to receive the subsidiary arm, whereby the subsidiary arm is movable within the guide channel.

13. The switch structure as claimed in claim 6 , wherein the restriction body is formed with a chamber and a guide channel, the chamber serving to receive the arm and the elastic member of the carrier body, the guide channel serving to receive the subsidiary arm, whereby the subsidiary arm is movable within the guide channel.

14. The switch structure as claimed in claim 7 , wherein the restriction body is formed with a chamber and a guide channel, the chamber serving to receive the arm and the elastic member of the carrier body, the guide channel serving to receive the subsidiary arm, whereby the subsidiary arm is movable within the guide channel.

15. The switch structure as claimed in claim 11 , wherein the restriction body has the form of a block body and the chamber and the guide channel are in adjacency to and in parallel to each other.

16. The switch structure as claimed in claim 12 , wherein the restriction body has the form of a block body and the chamber and the guide channel are in adjacency to and in parallel to each other.

17. The switch structure as claimed in claim 13 , wherein the restriction body has the form of a block body and the chamber and the guide channel are in adjacency to and in parallel to each other.

18. The switch structure as claimed in claim 14 , wherein the restriction body has the form of a block body and the chamber and the guide channel are in adjacency to and in parallel to each other.

19. The switch structure as claimed in claim 1 , wherein the retainer member makes the carrier body and the conductive metal member clamp and lock a flat-head terminal lead.

20. The switch structure as claimed in claim 1 , wherein the retainer member makes the carrier body and the conductive metal member clamp and lock a bare lead.

21. The switch structure as claimed in claim 2 , wherein the pivot hole is a threaded hole and the retainer member is tightened in the pivot hole of the conductive metal member.
