Abstract: The present invention relates to a magnetic latching relay which can avoid influences of erection stress on internal structure parameters thereof. The magnetic latching relay includes a yoke assembly, a magnetic steel assembly, a contact system having movable and immovable contact spring assemblies and a pusher pad, and a shell having a bottom case and an upper cover. Back contact springs of the movable contact spring assembly are arc-shaped and stacked on one side of each movable contact spring of the movable contact spring assembly. The bottom case has clip-shaped bosses which are formed outside two side walls of the bottom case to fasten extension ends of the movable and the immovable contact springs and supported with bolts to clamp the springs extending out of clip-shaped openings of the bosses.
