The present invention relates generally to manually controlling an apparatus and/or a multiplexer. More particularly, the present invention relates to controlling an apparatus and/or a multiplexer by signals that preferably include both proportional-output signals and rate-of-change signals. The signals may be generated by either tilt transducers or switches capable of producing an “on” and “off” signal. The signals may be used to control a primary apparatus connected to a control means and may alternatively be used to control a secondary apparatus connected to the same control means.
