Abstract: A drive mechanism (16A, 16B) including a rotary actuated motor (18) configured to rotatably drive a drive arm (24) between a first position to a second position and an actuator (30) responsive to movement of the arm, wherein the actuator is thermally isolated from the arm in both the first position and the second position to create a thermal barrier. The drive arm is configured to engage and advance the actuator between the first position and the second position, while remaining physically spaced from the actuator in the first position and the second position. The drive arm includes a recess (26) such as an opening, wherein the actuator has a member (30, 34) configured to reside in the recess and remain thermally isolated from the arm in both the first position and the second position. In one preferred embodiment, a shutter (14) of an imaging device (10) is positioned in response to the actuator, which shutter remains thermally isolated from the motor and arm. Other devices may be driven as well, such as switches.
