A push-push latch for latching with a keeper, the keeper having a hook, said push-push latch comprising:
- a housing defining a top opening and a front opening, said front opening having a resilient finger projecting therein;
- a beam having a top hook, said top hook being dimensioned and configured to mate with the hook of the keeper, a stem, a detent boss which extends along said stem, a central projection projecting from said stem, and a bottom arm, wherein said stem detent boss contacts said resilient finger for movement thereof as said beam is moved and said stem detent boss passes said finger;
- and
- a shuttle having an arm, said shuttle being spring-biased toward said top opening.

A push-push latch for latching with a keeper, the keeper having a hook, said push-push latch comprising:
- a housing having an interior wall and a ramp wall portion of said interior wall of said housing, said ramp wall being defined by a flat planar surface;
- a beam having a top hook, said top hook being dimensioned and configured to mate with the hook of the keeper, a stem, a projection extending from said stem, and a bottom arm, wherein said bottom arm engages said interior wall ramp wall portion to cause pivotal motion of said beam to disengage said top hook from the hook of the keeper;
- and a shuttle having an arm, said shuttle being spring-biased upward.
A push-push latch for latching with a keeper, the keeper having a hook, said push-push latch comprising:
- a housing having a bottom and a ramp formed therein, wherein the ramp is defined by a flat planar surface;
- a beam having a top hook, said top hook being dimensioned and configured to mate with the hook of the keeper, a stem, a projection extending from said stem, said projection having a flat top horizontal surface and a bottom ramped surface, and a bottom arm;
- and
- a shuttle, being movable downward toward said housing bottom and upward away therefrom having an arm, said shuttle being spring-biased upward, wherein said shuttle under movement is engageable with said beam projection to thereby move said beam toward said housing bottom when said shuttle is moved downward, and to thereby move said beam to move upward and away from said hook of said keeper when shuttle is moved upward
- wherein said bottom arm engages said ramp to cause a pivotal motion of said beam thereby causing said beam to disengage said top hook from the hook of the keeper.
