I've noticed that all of the buildings at my work have timer based lights so after 5pm they automatically turn off at least half the fixtures. In some buildings, these switches look like two white over/under buttons. In others, they look very similar to a standard toggle switch except they sit in the middle and you toggle them up/down.
The second type intrigues me because they are multi-way switches that come in multiple colors (including ivory/almond) and they are controllable by some kind of timer. Does anyone know what these might be? I have to believe they are some expensive units, but I' was wondering what corporations rely on for perfect operation? Obviously, I can't open the cover to find any markings and the switch itself is not marked such that I've been able to see.
