Some appliances are sold with a Sabbath Mode for those who observe the Jewish day of rest. Here are the notes for a Sub-Zero refrigerator:
- The door can be opened/closed at any time without concern of directly turning on or off any lights, digital readouts, solenoids, fans, valves, compressor, icons, tones or alarms.
- Any defrost cycle that becomes active will not be a function of the number of times or the length of time that the door is opened.
- The ice maker is disabled automatically. Ice cubes can then be made manually (using a standard ice cube tray) as needed for that Sabbath/Holiday.
- All dispenser functions are deactivated.
There are also special Shabbot elevators that stop on each floor so that no buttons need to be pushed. One could imagine a Sabbath Web Browser that would require no button pushing...it would just browse through a list of your favorite web sites automatically and you could dip in and read when you wanted.
