Abstract
A turn signal cancellation mechanism has an actuator and a pawl engagably interfacing therewith. In one aspect of the present invention, the pawl is disposed on an opposite side of a steering shaft from a handle interfacing segment of the actuator. In another aspect of the present invention, a unique pawl movably engages with a modified T-shaped slot within an actuator. A further aspect of the present invention provides a modularized system wherein a common housing interchangeably retains differing circuit boards, pivoting actuators coupled to handles, and various switches, depending on the specific options desired. In still another aspect of the present invention, a detent plunger has a shaft with a quadrilateral cross sectional shape along a portion thereof and an integrally formed semi-spherical cap. An improved fastening means is also employed to attach the present invention turn signal cancellation mechanism onto the steering column.
