Hotel DND solutions solves a simple concern that when people lived in room he don’t want be disturbed by housekeeper.
this is probably the
Origin
Hotel DND
Generally speaking, hotels are different from the residences. Hotel will provide a room service everyday. Then the room service will meet a privacy problem. Hotel DND solves the guest privacy problem.It is interesting to note that there is no law stipulating what a hotel DND should be designed to look like. Its trajectory is entirely natural.
Origin(door hanger)
DND signs(door hangers) are a very usual and conventional solution. It is so simple that you hardly can say it a ‘system’, But it is the origin DND solution. Or I preffer call it ‘method’. Actually today still many many hotels uses it because it is easy.
Switch/Doorplate
This is a completely ‘electric’ solution. It makes the do not disturb and makeup room sign completely electrical, forming a kind of switch-type thing that mounts on the wall.
As a conventional thinking logic, it is welldone.
Actually you will have many many choices.They may look very much different- to fit different electric wall mount standard, or different region popular styles.
Actually,you have 10,000 options in the sea of DND switch/doorplate.
There are different colors, different sizes, different features, different wiring models.
If you think about both of these, you’ll find an interesting thing.
The above two methods are two extremes.

Pauper’s choice-Origin

Rich’s choice-Doorplate/switch
- Need 110V or 220V AC power
- Expensive
- Looks deluxe, but huge amount of work
- Not easy lost or damaged and dirty

Hotel customers are hardly make choice between them.
If they don’t willing investing a lots of money on the switch or doorplate , they have to continue use the old door hangers.
This should not happen and that is why many hotels still use door hanger-everybody knows it is old, but at least it still working.
