Abstract
A novel actuator latch includes a catch portion interfering with actuator rotation with the latch in a closed position. The latch includes a first stop portion that is in contact with a fixed member with the latch in the closed position. The latch includes a pusher portion that is in contact with the actuator with the latch in the closed position and with the actuator in an extreme rotational position. The pusher portion has a torsional stiffness about the latch pivot location in the range 5 J/rad·secto 30 J/rad·sec, where Jis the rotational inertia of the actuator about the actuator pivot location expressed in units of kg·m. The first stop portion has a torsional stiffness about the latch pivot location that is at least 5 times that of the pusher portion.
