M MPapps New Member Mar 6, 2007 #1 Hi All, I am trying to design a circuit to do the following: Use a Momentary Push To Make Switch to toggle the input of a 7805 on/off The 7805 is supplied by regulated 12v so i need a circuit that switches its output between 0v and 12v using a Momentary Switch. I was hoping to find a design or at least a starting point somewhere but have had no luck so far. Any Suggestions / ideas would be great. Thanks
