Who faces the question of how the Raspberry properly on and off may not always pull the plug will be well served with this cable. Turning on the Raspberry Pi is due to a lack of switch known by connecting it to the power supply via USB cable. Then he will start automatically and boots its operating system from the SD card. You have to turn on him reverse way unfortunately: Pull the mains or USB connector.
This is exactly what the Camac USB cable with its "ON OFF Button Control switch" roundups with a 5V, 2A USB power adapter is the ideal solution: It saves just the sometimes quite fiddly plugging and unplugging the rear microUSB connector
