Abstract
A latch is controlled to latch and unlatch a device by using a portion of the insertion and extraction movement of the device being latched. The latch incorporates a pivoted latching member carried on the device being latched. The end or latching surface is positionable behind a latch bar, preventing the extraction of the latched device. The latch member is displaced to latch or release by a spring disposed between the frame of the device being latched and the latch member. When the actuator member is withdrawn from its ineffective position and if the latch arm occupies a latched position, the actuator member engages surfaces on the latch member and the module frame which are too closely spaced to permit free passage of the engaging portion of the actuator. This engagement with the surfaces results in spreading the engaged portions of the module frame and the latch member, thereby pivoting the latch member to unlatch the latching end of the latch member from a retaining surface.
