Abstract

An actuator with an override device to avoid damage to components during transition to and from manual operation and during manual operation. In one embodiment, the actuator comprises an output shaft, a drive assembly coupled with the output shaft, the drive assembly comprising a motor and a brake, an override device coupled with the output shaft, the override device comprising a gear assembly and a switch actuator, and a housing forming an enclosure about at least the gear assembly and the switch actuator. The switch actuator can be configured to modify an external input to the drive assembly in response to relocation of the gear assembly relative to the output shaft between a first position and a second position so as to disconnect the motor from the external input at the first position, disconnect both the motor and the brake from the external input at the second position, and apply the external input to the brake during transition between the first position and the second position.
