AntMiner ATX Power Supply Jumper Switch w/ LED light for PSU and Bitcoin Miner
I really like the idea of using this instead of a paper clip jumper. I also like being able to place the power switch where I want and the power LED is handy when I need to tell someone else how to turn my devices on or off.
I use it on a power supply for an Antminer S3+, makes it easier than having to jumper using a wire or making your own switch. Red light tells you it is working and it fits nicely in the power supply.
