A camera assembly has a main member having a mount defining an optical
axis. A rocker supported by the mount, is pivotable between first and
second positions. First and second taking lenses are movable by the
rocker between a first configuration, in which the optical axis
intersects the first lens and a second configuration, in which the
optical axis intersects the second lens. A linkage is switchable between
first and second conformations to pivot the rocker. The linkage includes
an inner link having an inner end rotatably joined to the rocker. The
inner end and rocker have overlapping projections holding them in
alignment relative to a plane perpendicular to the optical axis.
