This basic wireless light switch kit includes one wireless light switch and a 5A On/Off controller, preconfigured and ready to install. This kit can be used to control a light fixture, or another On/Off electrical load. Good for situations where you want to relocate a light switch or add a light switch to a pull-chain light. The controller is installed behind the light fixture and the switch can be mounted anywhere. Multiple kits can be installed in the same area without interference.
