That is the problem, low cost AND reliable don't go together. At best, you should be looking at moderate cost and reliable. Low cost means Made in China, and I bet you will have a hard time finding these push button switches, even well made reliable ones, made anywhere else. That is why there is such a trade imbalance with China. I figure, if I'm doing the labor to fix anything, I will put the best part I can find in place of the part that failed, so I will likely never have to do it again. Those sconces are most likely China made, so have cheap switches.
