X10 WS469 Push Button Relay Wall Switch

Turn on your ceiling & wall fixtures from anywhere in your house.
Push Button Style X10 Relay Wall Switch . Includes X10 updated relay ..
3-Way & Single Pole (On/Off only) Not a dimmer.
NOTE: This problem is most likely caused by line noise. The noise on the line stops the X10 signal from getting through so you can't turn the light on. BUT if you turn the light on from its push button, it puts a load across the line that attenuates the noise, so now you can dim or turn off the light. As soon as you turn it off, and remove the load, the noise pops back up. You need to determine the source of the noise and filter it..
