Hi guys! i'm getting stuck on this circuit. I know what i want but don't know how to do it... what i'm doing is a box that will have a lid which can open and close using a linear actuator(my own built one). what i want is that when i push a button (non momentary one i suppose) the actuator will push open the lid and when i push the button again the actuator will retract and close the lid. So i will be using a limit switch to kill power on the motor of the actuator when the box is fully opened and now at this stage i need to reverse polarity for the actuator to retract and when the lid is closed the limit switch will stop the motor again. So whatt i'm stuck on is the polarity switch, i want it to be a simple one push button and my original idea is to use if possible a touch sensor switch to replace the button, well does this exist a touch sensor switch that can reverse polarity? where can i buy this online? can i do this?
