Abstract
An HVAC actuator includes an output shaft rotatable between first and second end positions and a drive mechanism to selectively drive the output shaft toward the first end position. The actuator may include a light source within its housing and a window to provide visibility of the light from the light source to an observer. An aperture member may be situated between the light source and the window and be configured to move as the output shaft is rotated. The aperture member may have spaced openings that transmit the light to the window at a plurality of positions of the output shaft such that the aperture member may cause the appearance of blinking of the light through the window as the output shaft is rotated toward the first end position. One of the openings may be configured to be in registration with the light source at the first end position.
