摘要: A miniature magnetic latch relay including a support header, a permanent magnet, an armature in pivotal contact with the magnet and engaging a pair of switch contacts movable between corresponding pairs of fixed contacts, the armature being pivotally movable between two stable positions in response to selective energization of two electromagnetic coils, and a frame mounted in spaced relation to the header having magnetic core sections for the coils and pole piece sections for the armature, the frame supporting the permanent magnet and having an opening through which the magnet extends for pivotal contact with the armature. A barrier of non-magnetic material in the frame around the opening resists magnetic flux flow between the permanent magnet and the frame portion near the opening thereby forcing magnetic flux to flow between the permanent magnet and the armature. A formation on the end of the magnet is pivotally received in a groove in the armature and is retained therein under vibratory and shock load conditions by a retention tab and pin arrangement carried by the frame and spaced from the armature, the pin to armature spacing being less than the depth of the groove. The formation on the end of the permanent magnet is shaped to enhance flux coupling to the armature.
