The relay includes a housing containing an armature which is normally disposed in an inactive position, and which is pivoted by a manually operable button to an active position in which two sets of relay contacts are held closed by the armature. This pivotal movement of the armature also causes a flexible latch thereon to be engaged with the housing to latch the armature in its active position. After release of the button, if the relay coil is energized, the latch will disengage, and when the coil is thereafter deenergized the armature is released to its inactive position.
