Easy to install. Happy to get my lamp up and lighting again.
The ZE-03A dimmer switch was the only 300W replacement dimmer for our dining room China closet. It fit perfectly into the metal junction box on the cabinet and was easy to splice into the existing circuit. The only thing that would have made it perfect for my application would be a longer shaft. I do like the fact the case is made of plastic vs cardboard from other mfgr’s. The dimmer works perfect in the cabinet. I would highly recommend this dimmer switch.
