Description

Technical Field

[0001] The utility model relates to the technical field of detection switches, and particularly relates to a detection switch with high reliability. Background Art

[0002] A detection switch is a device that can sense changes in physical quantities and convert them into electrical signals for output. It plays a crucial role in various electronic devices and systems, and is used to monitor environmental conditions, device status, or perform specific detection tasks.

[0003] For example, a new type of detection switch disclosed in Chinese Patent Publication No. CN221262207U. The above new type of detection switch includes a base, an upper cover, a conductive terminal member, an elastic connecting member, and a rotating handle. The base is formed with a receiving groove and an opening that communicate with each other. The bottom wall of the receiving groove is provided with a socket column, and a fixing column is provided on the socket column; the conductive terminal member includes a first conductive terminal and a second conductive terminal. The elastic connecting member is sleeved on the socket column, and a first abutting contact rod and a second abutting contact rod are respectively provided at both ends of the elastic connecting member. The first end of the rotating handle is rotatably connected to the column body of the fixing column. The first abutting contact rod is connected to the bottom of the second end of the rotating handle, and the second end of the rotating handle movably passes through the opening. By rotating the second end of the rotating handle, the first abutting contact rod reliably abuts against the first conductive terminal, and the elastic performance of the elastic connecting member causes the second abutting contact rod to abut against the second conductive terminal. In this way, the contact between the elastic connecting member and the conductive terminal member is more reliable.

[0004] However, there is no insulating isolation structure between the elastic connecting member and the first conductive terminal in this patent. After the elastic connecting member undergoes elastic deformation and returns to its original position, the elastic connecting member is easily in contact with the first conductive terminal, resulting in the phenomenon of misconnection and affecting the detection information, resulting in low reliability in use. Moreover, the first abutting contact rod and the first conductive terminal are only in an abutting connection, resulting in a small contact area and thus poor conductive effect.

[0005] Therefore, the applicant has made a beneficial design and found a method to solve the above problems. The technical solution to be introduced below was generated under this background. Summary of the Utility Model

The socket rod includes a first socket part and a second socket part. A conductive torsion spring is sleeved on the first socket part.
