Hi Psyclone, great question. Our primary switch requires a neutral wire in order to keep constant power coming to it. In a three (3) way application or any other multi switch setup, an add-on is required because a typical standard switch does not have neutral connected, it will cause interference with the main switch causing it not to function correctly. If you have any further questions, please don't hesitate to respond or give us a call between the hours of 7:00 AM – 8:00 PM Central Standard Time, Monday thru Friday at 1-800-654-8483. Thank you.
Sorry, there was a problem. Please try again later.
