Last night I attempted to bring a little convenience to my kids room by making their room light work off the wall switch. Right now there is a wall switch that controls a receptacle on the south wall. Their lamp is on the north wall, therefore they've had to switch it on manually. I mistakenly thought that by replacing the wall switch with a regular X-10, push button style switch and setting its house and unit codes to match the lamp module that I had just plugged the lamp in to, it would work. Obviously (now) I realize that the wall switch doesn't put any X-10 commands on the line to control anything, it just listens and responds. Is there an X-10 wall switch that will control a lamp module, not by RF but with X-10 signals?

I think the terms are getting you a little confused.

X10 devices are transmitters, receivers, or transceivers. A transmitter transmits X10 commands over the power line while a receiver receives commands and controls a load. A transceiver converts non-X10 signals (IR or RF) into X10 commands.

What you need is a wall-mounted transmitter which can send commands to control your lamp module. You'd remove the existing switch, wire the outlet so that it's hot all the time, and install the in-wall transmitter such as the XPT1 or XPT4, either of which is $21.07. There are fancier, more expense in-wall transmitters but these would be fine for a kids room.

Just disconnect, cap, and label the traveler that's currently providing the switched power to the switched outlet so that the system can be restore at a later date.

Okay, let me see if I have this correct. The XPT is the transmitter base, this will send the X-10 command down the power line. The 1-W or 4-W part is simply a face plate that snaps onto the XPT that provides the 'buttons'.

That's correct, but you're getting the base/face combo for the $21.07. Use the XPT-1 for a one-button transmitter or the XPT-4 for a four-button transmitter.

The four-button version would let you add up to three more X10 controlled devices in the room.

I should also add that the following link shows some additional face plate choices. You could, for example, use the XP4D and have control of three lights plus the ability to control their intensity level.
