Shabbat elevator

A Shabbat elevator is an elevator which works in a special mode, operating automatically, to satisfy the Jewish law requiring Jews to abstain from operating electrical switches on Shabbat (the Sabbath).

Jewish law forbids those who observe it from undertaking various forms of "work" on the Sabbath, including that they may not create sparks or fires.

Shabbat elevators can be found in areas of large Jewish population in Israel, the United States, Canada, Australia, Ukraine (Dnipro), Argentina, and Brazil.

[9] In this mode, an elevator will stop automatically at every floor, allowing people to step in and out without having to press any buttons.

Otherwise, Jewish law prohibits observers from using an elevator on Shabbat in the usual manner, because pressing the button to operate the elevator closes a circuit, which is one of the activities prohibited on Shabbat and may also indirectly lead to "writing" of the new floor number in the display.
