An apparatus, including a chassis having an opening into which an electrical component is insertable, means for coupling to the electrical component, the means for coupling slidably movable, relative to the chassis, in a first direction generally away from the opening, and in a second direction generally toward the opening to a first position in response to force in the first direction exerted upon the means for coupling, and to a second position in response to force in the first direction exerted upon the means for coupling when the means for coupling is in the first position, wherein the first position is different, with respect to the chassis, than the second position.
