Abstract: A latch is capable of automatically latching and unlatching an implement, such as a thumb used on the stick of a hydraulic excavator. The thumb may be moved to a stored, inactive position by the operator and automatically latched, or locked, in that position by the latch. To automatically engage the latch, and latch the thumb in its stored position, the operator moves the thumb to its stored position under the force of the thumb actuator. To automatically disengage the latch, and unlatch the thumb, the operator moves the thumb out of its stored position. The force of the thumb on the latch will overcome the latch's unlatching force. But unintentional drifting of the thumb will not cause a force great enough on the latch to overcome the unlatching force and disengage the latch. Also, the latch can be easily manually disengaged by a technician.
