Abstract
A lever apparatus having a lever connected to a latch assembly is operable to open the latch when rotated to a second position from a first position under an actuation torque. The apparatus further includes a magnet assembly with first and second magnets operably coupled to the lever apparatus. The magnet assembly is operable to generate a return torque in an opposite direction to that of the actuation torque such that the lever is returned to the first position after the actuation torque is removed from the lever.
