Datasheet
USB Power Only Cable with Switch for charging your Raspberry Pi -
either Model B, A+, B+, or Pi 2. Just hook up the standard USB end to
a 5V 1A USB port power supply or 5V 2A USB port power supply and the
Micro B end to a Raspberry Pi and you have a Pi with a switch.
This cable will also work with anything that has a MicroUSB 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.
Cable Length: 5 feet / 1.5m
22 AWG wire
Switch is 43mm x 15mm x 12mm
