Abstract
An electro-mechanical latch includes a solenoid having an armature movable from a normally biased first position to a second position in response to an electrical current applied to the solenoid, and means for holding the armature in the second position to allow subsequent removal of the current from the solenoid. When the armature is in its first position, it is adapted to latch a device in a parked position. The armature is non-interactive with said device in its second position. The electro-mechanical latch of the present invention further includes means for releasing the holding of the armature in response to the device returning to its parked position whereby the armature returns to its normally biased first position to latch the device. An important advantage of the present invention is that the current need be applied to the solenoid only for moving the armature to release the device. The current may then be removed since the armature will be held in a position which is non-interactive with the device.
