Magnetic latching relay

Abstract

The present disclosure relates to a magnetic latching relay, including a case, an armature assembly and a microswitch. The armature assembly is movably assembled in the case, and the microswitch is configured to be triggered because of fitting with a movable action of the armature assembly. The case is provided with a cavity for mounting the armature assembly, a mounting groove is disposed at a position adjacent to the cavity, the microswitch includes a housing, a trigger spring piece and a plurality of pins. The trigger spring piece and the plurality of pins are respectively disposed at both ends of the housing, a first notch and a second notch are respectively provided on one side of a groove wall of the mounting groove close to the cavity and the other side of the groove wall of the mounting groove away from the cavity, the housing is fixed in the mounting groove, and the first notch and the second notch provide avoidance for the trigger spring piece and the plurality of pins, respectively. According to the present disclosure, the mounting and positioning of the microswitch can be facilitated, and the situation where the plurality of pins abut against the inner wall of the mounting groove to bend and deform or debris is generated by the friction between the pins with the inner wall of the mounting groove can be avoided.
