The Draper 121001 SS-1R Motorized Screen and Lift Rocker Switch is used to control Draper Projector Lifts and Screens. The Switch is a black rocker switch with an aluminum cover plate that is finished with silver satin. It includes three 6" wire leads: black, red, and blue (common, down, and up) and fits into a standard single-gang box. If needed, the SS-1R can be used with the Power Supply Key Switch for security purposes. This way, the Rocker Switch can not be used without the proper key. These items are available in a Kit as well.
