This is a direct OEM replacement for the original factory-installed switch, providing exact compatibility and function—no modifications required. It is designed specifically for the DTU03 drive-thru series and automatically activates the air curtain when the door/window opens and deactivates it when closed, helping maintain energy efficiency, insect control, and temperature separation.

120V operation for standard compatibility
Durable build suited to high-traffic drive-thru settings
