1. An information handling system comprising:
a circuit board having a receptacle connector mounted to a surface of the circuit board and having a post mounted to the surface of the circuit board; and
an information handling resource assembly comprising:
a housing for carrying an information handling resource having an edge connector configured to mechanically and electrically couple to the receptacle connector; and
a latch assembly comprising:
a support fixedly coupled to the housing;
a handle rotatably coupled to one of the support and the housing via a first axis and rotatable between an unlatched position and a latched position relative to the support; and
a catch arm rotatably coupled to the handle via a second axis and arranged such that:
as the handle is rotated from the unlatched position to an intermediate position between the unlatched position and the latched position, the catch arm is translated in an arc from a first position in which it is disengaged from the post to a second position in which a retention feature of the catch arm positions itself under and proximate to a ledge of the post; and
as the handle is rotated from the intermediate position to the latched position, the catch arm and the retention feature move in a direction away from and perpendicular to the surface of the motherboard to a third position in order to secure the retention feature to the ledge and drive a mechanical force to mate the receptacle connector and the edge connector.
