The invention provides an apparatus for engaging and disengaging a track
lighting assembly with respect to a track in a track lighting system. The
apparatus includes a track engaging apparatus that includes a housing.
The housing includes a rotation inhibitor that has a protruding end that
protrudes from the housing for engaging with the track and preventing the
track engaging apparatus from rotating with respect to the track. The
rotation inhibitor further includes a receiving member for translating a
force in a first direction into motion of the rotation inhibitor in a
second direction substantially orthogonal to the first direction. The
apparatus further includes an actuator for applying the force in the
first direction to the receiving member.
