Da-Lite Key Operated 110 Volt Switch Series

A flush-mount wall switch for a 115 V Da-Lite electric screen that only works with a key in it. In a lecture hall, a gym or a church hall, that is the difference between a screen that comes down when the AV tech decides and a screen that comes down whenever a student finds the button.

It installs in a standard wall box in place of an ordinary screen switch and ships with a white cover plate, so the finished wall looks like every other plate in the room. This is the 115 V line-voltage version - it is not a low-voltage control and does not substitute for one. Da-Lite part number 74490.
