Shabbat elevator

Shabbat elevator is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Shabbat elevator rather than just read about it. In short: A Shabbat elevator is an elevator which works in a special mode, operating automatically, to satisfy the Jewish religious law requiring Jews to abstain from operating electrical switches on Shabbat. These are also known as Sabbath elevators or Shabbos elevators.

Key takeaways

  • Shabbat elevator belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Shabbat elevator to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Shabbat elevator from memory before moving on to harder problems.

Reference excerpt

A Shabbat elevator is an elevator which works in a special mode, operating automatically, to satisfy the Jewish religious law requiring Jews to abstain from operating electrical switches on Shabbat. These are also known as Sabbath elevators or Shabbos elevators.

Description and history

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. In recent times, this has been extrapolated to also cover the operation of electrical lights and other appliances. An elevator may be marked with a sign noting that it is specially configured for Shabbat observance. A Shabbat elevator typically stops at every floor without requiring its passengers to push buttons, which would violate Shabbat observance; however, some rabbinical scholars object to the use of Shabbat elevators as halachically problematic on other grounds. Shabbat elevators can be found in areas of large Jewish population such as in Israel, the United States, Canada, Australia, Ukraine, Argentina, and Brazil. They are found in hotels, hospitals and other health institutions, apartment buildings, and sometimes in synagogues. The Israeli Knesset in 2001 passed a Shabbat elevator law ordering that in all future construction of residential and public buildings which will have more than one elevator, one elevator must have a Sabbath mode. In this mode, the elevator will stop automatically at every floor, allowing people to step in and out without having to press any buttons. In 2009, a number of Israeli Haredi rabbis, led by Rabbi Yosef Shalom Elyashiv and including Rabbi Nissim Karelitz, Rabbi Chaim Kanievsky, and Rabbi Shmuel Wosner, published a religious injunction forbidding the use of Shabbat elevators. This opinion was criticized by Rabbi Yisrael Rosen, Orthodox rabbi and founder of the Israeli Tzomet Institue for Halacha and Technology, as being contrary to the earlier authoritative ruling of Rabbi Shlomo Zalman Auerbach. Some interpreters believe that a non-Jew known as a "Shabbos goy" may not be employed to press the buttons and hold the door for Jews in buildings that do not have Shabbat elevators, unless the Jew has great difficulty using the stairs themselves. As discussed in that article, a non-Jew is not expected to keep the Sabbath like a Jew. Therefore, Jewish law holds that a Jew may benefit from work performed by a non-Jew only if the non-Jew performs this work for his own good and of his own free will. A borderline case is when a Jew hints to a non-Jew that they would like them to perform a certain service without explicitly asking. These borderline cases are not considered legitimate by many Orthodox rabbis.

Worked examples

Example 1 — a first encounter with Shabbat elevator

Start with the simplest possible case. Write down what Shabbat elevator claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Shabbat elevator before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Shabbat elevator ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Shabbat elevator

In research
Shabbat elevator appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Shabbat elevator in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Shabbat elevator is common in secondary-school and first-year university syllabi. It links to neighbouring topics Elevators, Shabbat innovations, so understanding it makes those chapters shorter.
In everyday life
Look for Shabbat elevator outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Shabbat elevator in simple terms?

A Shabbat elevator is an elevator which works in a special mode, operating automatically, to satisfy the Jewish religious law requiring Jews to abstain from operating electrical switches on Shabbat. These are also known as Sabbath elevators or Shabbos elevators.

Why does Shabbat elevator matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Shabbat elevator?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
