My article in the November 2014 issue of Nuts and Volts describes how to use a single push-button switch to turn your projects on and off, just as you do with your modern electronic devices. Click on the title page image at the right to see the entire article. You can also see the entire issue at Nut and Volts Magazine Online.
The point of it is to replace the often bulky toggle and slide power switches with a single power button. In fact, this button may have other uses once the device is turned on. This capability is supported by most microprocessors and you can probably add this feature to your project for little to no extra cost.
