1. A latch module, for connecting to a retaining pin of a chassis, comprising:

  • a button carriage comprising a user-operable button,wherein the button carriage is slidably coupled to a latch module chassis of the latch module, thereby enabling the button carriage to move between an extended and a depressed position with respect to the latch module chassis, andwherein the button carriage, when the button is depressed a first time, moves from the extended position to the depressed position;

    an inverter arm,wherein the inverter arm is pivotally coupled to the latch module chassis,wherein the inverter arm is mechanically linked to the button carriage at a first end of the inverter arm, andwherein the button carriage, moving from the extended position to the depressed position, as the button is depressed, causes the inverter arm to pivot;

    a latch arm, mechanically linked to a second end of the inverter arm,wherein the latch arm is slidably coupled to the latch module chassis,wherein pivoting of the inverter arm causes the latch arm to slide from a non-blocking position into a blocking position,wherein, in the blocking position, the latch arm extends toward and makes contact with the retaining pin of the chassis, andwherein, in the non-blocking position, the latch arm is away from and not in contact with the retaining pin of the chassis; and

    a latch biasing spring between the button carriage and the inverter arm, generating a biasing force that, in the blocking position, causes the inverter arm to exert a force against the retaining pin.
