Can I use the Lightning SwitchTM with my existing mechanical light switch?
No. Since the mechanical switch turns On and Off the electricity to the entire system the mechanical switch cannot work together with remote control switches. In order to use Lightning products in such a system, you would remove the existing mechanical switch and connect the wires together that are now attached to the mechanical switch. This would result in that circuit always being “On”. You could then install a Wire-In Lightning Receiver in or adjacent to the electrical junction box at the light fixture… and install as many Lightning Transmitters as you want to service that light. The Lightning Large Frame Transmitter is designed to screw right over the wall junction box in which your mechanical switch is now located, so you wouldn’t have an empty box left on your wall.
