it is the on - off switch for the Audiovox after market cruise control that I started off with a year or two ago, on powers the system up and off shuts it down. Set and resume are self explanatory and if the system is operating, set accelerates and resume coasts.
I can see how closing the brown contact gets things running, but how does the stop contact make it stop, my first thoughts were that it shorted base to emitter and caused it to shut down similar to turning off and SCR. Any one else have any ideas?
