Add an inline power switch to any device using the standard 2.1 x 5.5mm DC Barrel standard! This cable is a short extension cable with a SPST switch in the middle and makes adding a power switch inline with one of many “wall-wart” power supplies as easy as possible.

The cable measures 300mm in length, with a DC barrel plug on one end and DC barrel jack on the other end. The switch is located at the midpoint and carries a rating of 2A and 125V, however at 12V or less, we figure it is good for 5A.
