I've built many project boxes with switches over the decades, but I've never worked with switches worse. The quality is terrible. There were so many functional flaws in this line of switches; including switches where the toggle switch was stuck and not moving or only moving halfway to a different position, loose terminals that wiggled open or closed when they weren't supposed to, contacts that wouldn't close and didn't open all the time when the switch is moved to a different position. Then there were mechanical defects like a notch in the threaded neck that wasn't aligned like the rest. So if you used a washer with tabs in the hole to align the switch with the corresponding hole in your panel or box, the switch switch would be rotated to the side of the expected alignment; and the tabs on these washers were almost flat so you have to bend them by hand to fit the alignment holes in your plate or box. There were also blemishes, such as holes in the switch nuts that were clearly off-center. Overall these switches are of extremely poor quality and I would not recommend anyone to buy them for any purpose.
