This INSTEON SwitchLinc On/Off Switch (Dual-Band) Model 2477S was removed in a condition where the switch works most of the time, however, there are some times where the switch seems to be "frozen" and does not switch when requested.  Therefore, this product is listed AS-IS with no returns.  You may find that this switch will work for you.  However, there's a chance this switch may have limited life and only be good for parts.  The decreased price is a reflection of that.  Purchase at your discretion.
