Analysis of bistable electromagnetic relays design features

This paper pays attention to a classification of bistable electromagnetic relays. The following signs of the classification of mentioned relays are emphasized, such as: design, type of contact fixation, relay contact diagram, type of current and value of the control voltage of the coil, the number of coils, nature of the load switched by the relay; the power consumed by the coil, and others. The undertaken classification systematizes information on the design, technical and functional features and parameters of such relays and demonstrates the current level of technical development of relays that are mentioned above. A conclusion is made concerning tendencies and directions of bistable electromagnetic relays capabilities developing in the future by the authors.
