The Draper 121032 KS-1/SS-1R Single Station Rocker Switch and Power Supply Key Switch Kit combines the Single Station Rocker Switch and Power Supply Key Switch into one kit. The 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.
The Power Supply Key Switch mounts next to the operating switch and controls power to it. The Key Switch can interrupt the power to any control, however, it is mainly intended for use with the SS-1R Single Station Control, or MS-3R and MS-4R Multi-Station Controls, where the safety feature of key control is also required. The Key Switch will interrupt the power to the Rocker Switch so that is can only be used when the key is inserted and turned to the ON position.
