X-10 PRO PLW02 X-10 PLW02 WALL SWITCH/ LINE;

IMPORTANT NOTE: When two switches control the same light, it's called a three-way circuit. A three-switch system is a four-way circuit, etc. Each three-way circuit requires one master switch and one companion switch. For circuits with more than two switches, simply add additional companion switches for each additional switch. The X10 wall switch can only be used with incandescent lights. All X10 compatible dimmer switches and modules rely on the conduction path through the incandescent bulb filament and will not work properly with other loads. For halogen or fluorescent, use an appliance module. Wall plates sold separately.
