ABSTRACT:
A multiple mode control lever assembly includes a lever fixed for rotation with a disk rotatable on a central pivot in a housing. The disk includes detent recesses and carries a brake segment. A detent element is pivotal about a second pivot and carries a roller engageable with the detent recesses. A brake element is also pivotal about the second pivot and carries a brake shoe engageable with the brake segment. An index cam is rotatable on the central pivot to couple and uncouple the detent and friction elements from the disk. The index cam is rotated by a ratchet with a pawl reciprocated by a solenoid fixed in the housing. A centering spring continuously coupled between the housing and the disk urges the lever to a neutral position.
