I have a rather small X-10 setup in our apartment including two standard X-10/RadioShack wall switches (the WS467), I believe.

They have a tendancy to turn themselves on in the middle of the night if not "locked off" with the slider at the bottom of the switch. Both of them do this, so I get the impression that this is somewhat of a design flaw (I've read about lots of other people with the same problem).

I've tried some of the fixes with limited results.

What I want to know is if there are higher quality switches from different brands that are less prone to this problem - PCS models or the like.
