Wireless RF Remote Control System

Wall Mounted Switch RFA-108 and Plug-in Receiver RFA-110
This wireless Radio Frequency (RF) control is an easy, convenient way to add switched outlet convenience without any wiring or electrician needed. The invisible RF signal passes through walls, doors, ceilings, floors and even around corners. Simply plug the desired appliance into the receiver and the receiver into any outlet. The transmitter is designed to look just like an actual switch and switchplate and mounts to any surface with the enclosed screws. A press of the transmitter’s toggle switch turns whatever you’ve
plugged into the receiver on or off – just like a hardwired switch and outlet!
Channel Code Information
Three operating channels are available so you can control three separate systems at different locations in your home. Be sure to match common frequency channels, for those devices you want to be operated by the same switch.


Notes: The total load of appliances connected to the Plug-in Receiver should not exceed 1200 Watts or 10 Amps.
Do not use Plug-in Receiver to control appliance loads that may be dangerous to turn on remotely (i.e. power tools).
The Plug-in Receiver must be located within 100 feet of the Wall Transmitter.

  • Remove the Front Cover of the Wall Transmitter by turning the two white Cover Screws on the Front Cover counter-clockwise.
  • Remove plastic Battery Tab by gently pulling it from Battery Compartment (this tab isolates the battery until it’s ready for use and ensures that you’ll have a fresh battery).
  • Reinstall Front Cover using 2 Cover Screws. Set Wall Transmitter aside.
  • Plug your light/appliance into the outlet on the Receiver being careful to match the wide blade of the light/appliance (if equipped) with the wide slot on the outlet.
  • Plug the Receiver into any standard grounded 110/120 Volt outlet being careful to match the wide blade of the Receiver with the wide slot on the outlet. Fully insert.
  • Before mounting your Wall Transmitter, hold your Wall Transmitter at the location where you wish to install it.
  • Press Toggle Switch to determine if your light/appliance turns on and off. If your light/appliance does not respond try relocating the Transmitter or Receiver. Large metal objects such as metal doors or cabinets should not be in the way of the Wall Transmitter and Plug-in Receiver since this could decrease the range of the RF signal.
  • Once you have successfully completed this test, remove Front Cover once again and mount Wall Transmitter with two enclosed Mounting Screws. (Surfaces other than wood  may require a different  type of mounting hardware.)
  • Replace the Front Cover of the Wall Transmitter and secure to wall switch with white Cover Screws (do not overtighten).


Simply press the Toggle Switch to turn the light/appliance you’ve plugged into the Receiver on or off.
Note: Wait at least 3 seconds after you press the transmitter on or off before you press it again. This allows for the RF signal transmission to be completed.


Your RFK100 battery should last 2-3 years under normal use.
To replace the battery:

  • Remove the Front Cover of the Wall Transmitter by turning the two white Cover Screws on the Front counter-clockwise.
  • Remove the battery from Battery Compartment and replace it with another 12Volt battery (Radio Shack™ 23, 23M, VR22, EL22 or equivalent).
  • Replace Front Cover and Screw.
