This USB to Micro USB Cable with switch is 1.5m long and is the perfect hard on/off power switch for your Raspberr Pi. This cable can be using in conjunction with a USB mains charger and it's made with 22AWG wire, so it's thick enough to allow > 2A current!
This cable will also work with anything that has a Micro USB port. This cable does not transfer data - so it's mostly just good for powering and charging devices - but adding an on/off switch to your power supply is a nice addition and one that we absolutely love clicking.
We've sized this USB to Micro USB cable to fit ALL Raspberry Pi cases available
