Therefore, the circuit plays the roles of automatic regulation, safety protection, circuit conversion and the like.

A conventional relay includes a housing, a base, a movable spring assembly, a stationary spring assembly, and a linkage, wherein the movable spring assembly, the stationary spring assembly, and the linkage are respectively mounted to the base. The base is covered on the shell. The movable spring assembly and the linkage are both sealingly disposed within the housing. The movable spring assembly comprises a movable spring plate and a movable contact bulge, wherein the movable contact bulge is installed on the movable spring plate, and the movable spring plate is connected to the linkage device in a linkage mode. The static spring assembly comprises at least one static spring piece and at least one static contact bulge, wherein the static contact bulge is arranged on the static spring piece and is opposite to the movable contact bulge. When the movable spring plate is linked with the linkage device, the movable contact bulge on the movable spring plate and the static contact bulge on the static spring plate can be switched between a contact state/separation state and a separation state/contact state.

During the process of assembling the relay, especially during the process of assembling the static reed, a part of the static reed is usually inserted into a mounting groove preset in the base.

It will be appreciated by those skilled in the art that the coil member 211 may be configured to include a coil, core, or the like. The present invention is not limited in this respect.

It will also be appreciated by those skilled in the art that as the coil member 211 is subjected to a voltage differential, the yoke 212 will magnetically attract the armature 213. The armature 213 then moves closer to the yoke 212 against the spring force of the spring 214. The linkage end 2202 of the linkage rod 22 will then be pulled by the armature 213. Accordingly, the movable spring 31 mounted to the driving end 2201 of the linkage rod 22 will be located at the first stationary spring 41a on the side of the movable spring 31. When the coil member 211 has no voltage difference, the yoke 212 will be magnetically vanished. The armature 213 is reset by the spring 214. The linkage end 2202 of the linkage rod 22 will then be pushed by the armature 213.
