WARNING: Cancer and Reproductive Harm –


Control Up To Four X10 Receivers

Create a custom X10 wall switch with the X10 PRO Wall Transmitter Base Module. This X10 transmitter installs in a standard single-gang wall box and wires into your powerline. Simply decide how many X10 receivers (1, 2, or 4) you want to control with the X10 PRO XPT switch, and then attach the appropriate keypad faceplate (sold separately). Once installed, you have both local and X10 remote control over your X10 receivers!

  • Combines with any XPT keypad to create a custom X10 switch
  • Controls up to four sequential X10 unit codes
  • Connects to Hot and Neutral wires
  • Mounts in a single-gang wall box

How It Works

The X10 transmitter base can control multiple X10 receivers by running the Unit Number Addresses in sequential order. In other words, if you have the dials on the transmitter base set to House Code B and Unit Code 4, a four-button keypad will control the X10 receivers set to House Code B and Unit Codes 4, 5, 6 and 7. The top button will control Unit Code 4, the next button below will control Unit Code 5, and so on.


  • X10 transmitter requires an X10 PRO XPT Series Keypad (sold separately).
  • Due to X10 Product changes, these Transmitter Bases are not compatible with Transmitter Bases sold before July 2007.

The X10 PRO Wall Transmitter Base Module is an X10 Wired-In Transmitter

A basic X10 system includes a Transmitter and a Receiver – both sold separately. Transmitters are control devices that send X10 signals through your home's electrical wiring to X10 Receivers. When a Receiver receives a command, it responds by turning a light, appliance or other electrical device On or Off, and sometimes Dim or Bright.

X10 Makes It So Easy To Automate Your Home!

X10 began manufacturing home automation and security products in the late 70s, establishing X10 as a smart home standard. X10 utilizes powerline technology to transmit control signals anywhere in your house over your existing electrical lines, so you can control lights and appliances throughout your home without running new wires! Have complete, automated control over lights and appliances from anywhere in your home with X10.
