I am developing some electronics (about 200mA draw) which are powered by 2 AA batteries in series using a MCP1640 converter for having clean 3.3v. Just like many of its colleagues, the MCP has an enable pin that - when pulled to ground - disables power output and consumes about 1 uA. Google couldn…

Manual switches are very restrictive, but if your project is suitable for manual manipulation, by all means. 0 is less than 1 any way you slice it.
