A latch assembly includes a housing having a cavity between first and second end walls. The housing includes first and second journal members and first and second swing arm apertures at the second end wall. A swing arm member having a joining end is positioned within the cavity having first and second swing arms connected to the joining end having portions extending freely through the first and second swing arm apertures. A keeper/catch member is rotatably connected to the first and second journal members. Keeper/catch member rotation from an orientation rotated away from a longitudinal axis defined by a portion of the first and second swing arms extending through the swing arm apertures to an orientation approximately parallel with the longitudinal axis creates an over-center locking condition for the housing and a pushing force acting through the keeper/catch member to push a first component into contact with a second component.
