Abstract
A relay has an abutment mounted adjacent its armature for movement therewith. A spring-biased tapered pin engages the abutment when the relay is energized. This causes the relay to maintain a latched, first switch state. An electromagnetic releaser is then energized which displaces the pin thus freeing the armature. A spring returns the armature to an unlatched position whereby the relay is set to a second switch state.
Claims10
A latch relay assembly comprising:
- a coil having an armature mounted in movable relation therewith;
- switching means connected to the armature for switching the relay between at least two states;
- abutment means, of relatively low mass, connected to the armature;
- movable plunger means mounted adjacent the abutment means for abutting the abutment means near the center of gravity of the armature, when the relay is energized, thus latching the relay in a first relay state;
- and
- electrical means connected to the plunger means for releasing the plunger means from abutting the abutment means thus returning the relay to a second relay state, when the relay is de-energized;
- whereby the relatively low mass of the abutment means and the disposition of the plunger means near the center of gravity of the armature render the relay resistant to shock and vibration.

The latch relay comprising:
- a coil;
- an armature positioned in movable spaced relation to the coil;
- an insulator yoke mounted perpendicularly to the armature;
- low mass support means connected in cantilever fashion to the yoke, in parallel spaced relation to the armature;
- low mass abutment means mounted to the outward end of the support means;
- and
- plunger means mounted near the armature center of gravity for abutting the abutment means when the relay is energized, thus latching the armature in a first state;
- and
- electromagnetic means connected to the plunger means for terminating the abutting relationship, thus returning the armature to a second state when the relay is de-energized;
- whereby the relatively low mass of the abutment means and the disposition of the plunger means near the center of gravity of the armature render the relay resistant to shock and vibration.
