Thank you Roger, that's how I had it originally wired. Maybe something is wrong with my WS469 switch. I don't know how the relay in the WS469 is designed to work electrically. Could it be to simulate an SPDT switch with the black lead being the center pole and the red and blue leads being the outer poles? I know that the signal has to reach the WS469 from the CS277 to activate it.
SPST switch. Turns On and Off from the Line to the Blue (Common to Lamp wire) on the WS469.
Line is also connected to one of the Blue wires on the CS277. The other Blue capped off for safety as both are tied together.
When you push the CS277 it connects the 120 volt Line back to the Trigger input of the WS469. From CS277 Blue to Red.
The Red trigger is activated by putting 120 volts from the line on it.
It maybe a wiring error. As I have see a few different ways a three way can be wired.
I have one where the Load and Line are both in the main electrical box and the other one is connected back to it on the three wire cable.
I have also seen some. Where the Line is in one box and the Load in the other box. So how you wire it may depend on exactly what you have.
