Abstract: A combination throttle/shift control system, configured for providing the full control of throttle and shift functions on a single lever, taught in the exemplary embodiment in conjunction with a marine propulsion system. The preferred embodiment of the present invention allows the full control of propulsion systems throttle and control functions in a single lever, as opposed to most traditional designs, which require the utilization of separate control levers and cables. This is accomplished via the utilization of a relay triggered actuator arrangement wherein there is provided a magnetic switch system for monitoring the positioning of the actuator travel rod relative a switched relay system. The present invention simplifies both the use and mechanical complexity of throttle and shift control systems, resulting in an appreciable increase in the ease of use, while reducing overall expense and maintenance requirements.
