The Draper 121002 MS-3R/MS-4R Multi-Station 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.
MS-3R and MS-4R are 2 station 115V controls that are similar in appearance and features to the Single Station Control. Automatic override allows only one signal to reach the motor when switches are operated simultaneously. The Multi-Station switches act like a 3-way light switch by allowing control of the Motorized Lift or Screen from either of the two stations. For more than two locations, add the Multi-Station Add-On Switch.
