ABSTRACT:
A transmission shift position indicator has a rotatable drum with a cam track formed in the outer periphery thereof. A cam follower is disposed in the cam track and operatively connected to a housing through a base portion for linear movement thereon in response to rotation of the drum. The base portion has a pointer connected thereto which is alignable with indicia imprinted on the housing to indicate the selected transmission operating condition. The cam track has portions thereof formed oblique to the longitudinal axis of the drum which cooperate with the follower to cause the linear movement of the base portion and circumferential portion transverse to the longitudinal axis interconnected by adjacent oblique portions for permitting the pointer to dwell at selected indicia position during rotation of the drum.
