Ws12a Wall switch not working, outlets all work - all on same circuit

[TheOriginalMrT]

I have a strange deal going on my wall switch (ws12a wired single) stopped working one day after a storm. I figured it was knocked out by lightning so I replaced it with a new one - nothing. So I tried another new one still nothing. Oddly the outlet units still work and they are on the same breaker as the wall switch. Any ideas?

Something else is probably causing interference.
You may need to do a "breaker box test" to see which circuit is causing the interference.
