I am not sure what you have seen but we had x-10 switches that look exactly like modern decor switches. Touch them once (on the top) to turn on and tap the top again to shut them off, or control them remotely from any x-10 compatible control. They even make remote switches that look just like that same modern decor switch, but don't have to be physically wire to the other switch; I used them in garage lighting essentially adding 4 way switches without messing with wiring. They do make some that are on/off with no dimming, they cost a bit more which is funny since they don't need to dim. The thing I didn’t like about them was sometimes the remote control was just flakey, sometimes working sometimes not, but it was easy to add and wire up.
