I had to buy this, because when I would run my dryer, it kept tripping the breaker. I found out that I needed to replace this breaker switch for it. It was replaced as soon as I received this. My dryer has been running great ever since. So glad I ordered this item.

This product was just what I needed as a replacement for another one that for some reason went bad. The first one shipped would not switch out of the neutral position, so the customer was kind enough to send another one that did work, at no extra charge. It is good to know that there are companies that will stock and ship these items that cannot be purchased at the local hardware store, and that they guarantee their products. If I ever need another, I know now where to go to find it.
