  • Patent number: 11404232
    Abstract: An electromagnetic relay capable of externally and manually controlling, turning on, and shutting off electric power includes casing, push-pull rod and relay module. The casing has top cover, where slideway is formed, and an end of the slideway has bump. The push-pull rod is installed to the slideway and has an end formed into hook portion and passed into the casing. An open slot, which has fitting hole and sliding hole, is formed on the push-pull rod. The relay module is installed at the chassis and has elastic contact plate assembly and lever, and an end of the lever is engaged with the hook portion. After the fitting hole is sheathed on the bump, the sliding hole is moved relative to the bump, so that the hook portion drives the lever to push the elastic contact plate assembly to define electrical connection or disconnection state according to different requirements.

  • Patent number: 10522312
    Abstract: A movable spring plate structure for defining an open or closed state with respect to a fixed contact includes a rigid spring plate contact portion, a soft spring plate warp portion, a soft spring plate force-applying portion and a movable contact. The soft spring plate warp portion is coupled to the rigid spring plate contact portion, and a first deformation gap is formed between the rigid and soft spring plate contact portions. The rigid spring plate contact portion is harder than the soft spring plate warp portion. The soft spring plate force-applying portion is disposed at the soft spring plate warp portion, and the movable contact is disposed at the rigid spring plate contact portion. A force applied to the soft spring plate force-applying portion drives the movable and fixed contacts into a closed state.
