Product review (5 stars): Solid Switch For Your RepRap Printer
The product works well. It does not come with a fuse, and I don't recommend trying to solder to the connections (i was careless on one and melted all the plastic around the front of the pin) but a crimp spade makes a nice solid connections. I looked up a video on youtube on how to wire it to where the light always stays on, or where the light in the switch is just on when the power is on. All and all, the product feels solidly made, I've been running mine for about 6 months now and it still seems to work without any issue.
