Daniel was getting ready to close a multimillion dollar deal in the coming days. He traveled to Beijing to sign the contract, but the customer had to excuse himself as an emergency came up. The customers assistant informed him that something happened to his boss' grandmother and that he needed a few days before they can meet to close the deal. It was Thursday and Daniels flight was in an hour, but he knew that if he left now he could potentially lose the deal of a lifetime. On the flipside, he knew a delay meant he would have to spend Shabbat in Beijing. He decided to check into a nearby hotel. Luckily, his wife packed him extra clothes and even some frozen mazza cause we all know SY's can't survive without mazza on Shabbat. After unpacking he decided to take a walk around the hotel. As he went from area to area, he noticed how everything was automatic. Walking into a room caused the lights and AC to automatically turn on. The toilets flushed on their own and the sinks went on and off all by themselves, no turning of the knob required. And then, it hit him; everything runs on electric! What is he going to do about Shabbat?
- What is the Halacha regarding the following items on Shabbat
- Going on elevators
- Using a toilet with automatic flush
- Using a sink with automatic on/off button
- Walking through a door with a sensor
- Using a swipe card to get into a room

החכם עיניו בראשו . בתחלת הדבר מסתכל מה יהא בסופו:
That being said, if you are caught in a situation, like the scenario mentioned above, we want to make sure you know what to do. So let's learn!
It is important to note that regarding the use of electricity on Shabbat, there is a difference between turning on something electric (a fan) to turning on a light (your dining room light fixtures). The former involves completing an electrical circuit while the latter involves heating up an element until it glows and produces light. According to almost all poskim, turning on a light is an Issur Deoraita (prohibition from the Torah) while completing a circuit is an Issur Derabanan (Rabbinic prohibition) It is important to keep these ideas in mind when figuring out solutions to our halachic questions.
- Obviously using electricity on Shabbat is a violation and therefore cannot be done directly. The question now is whether there are other ways to get around the prohibition.
- Would you be allowed to ask a non-Jew to perform the act?
מתני׳ נכרי שבא לכבות אין אומרים לו כבה ואל תכבה מפני שאין שביתתו עליהן
Mishna: A gentile who comes to extinguish a flame, we do not say to him, "extinguish" or "do not extinguish" because his "resting" is not our obligation
It is not the duty of Israelites to see that he rests on the Sabbath unless he is his slave
The Rambam, Hilchot Shabbat 6:1, writes that the prohibition against amira l'nochri is based on a concern that the Jew who asks the non-Jew to perform the prohibited activity may treat Shabbat lightly and eventually perform the prohibited activity himself.
- So I can't directly tell a non jew to perform an act that would be assur for me. But can I benefit from an action he did for me without me asking him?
מתני׳ נכרי שהדליק את הנר משתמש לאורו ישראל ואם בשביל ישראל אסור מילא מים להשקות בהמתו משקה אחריו ישראל ואם בשביל ישראל אסור עשה נכרי כבש לירד בו יורד אחריו ישראל ואם בשביל ישראל אסור
MISHNAH. IF A GENTILE LIGHTS A LAMP, AN ISRAELITE MAY MAKE USE OF ITS LIGHT; BUT IF [HE DOES IT] FOR THE SAKE OF THE ISRAELITE, IT IS FORBIDDEN. IF HE DRAWS WATER8 TO GIVE HIS OWN ANIMAL, TO DRINK, AN ISRAELITE MAY WATER [HIS] AFTER HIM; BUT IF [HE DRAWS IT] FOR THE ISRAELITES SAKE, IT IS FORBIDDEN. IF A GENTILE MAKES A STAIRWAY TO DESCEND BY IT,9 AN ISRAELITE MAY DESCEND AFTER HIM; BUT IF ON THE ISRAELITES ACCOUNT, IT IS FORBIDDEN.

This is the reason why we are allowed to open a fridge on Shabbat even though you are letting in warm air and may cause the motor to turn on. Since you don't know if the amount of air you are letting in will trigger the sensor, you are allowed to open the fridge without worrying about it.
Could this apply to the automatic AC you have in your room?
- Melacha she'einah tzricha legufah (an action not needed for its result). This occurs when one does a prohibited action on Shabbat not intending to commit the action prohibited by halacha. For example, pouring water on a field to dispose of the water, rather than to irrigate the field. Since your purpose was just to get rid of water, even though you did an action (a melacha) it wasn't in order to gain from that action (she'eina tzericha legufah.) This is normally a rabbinic violation.
- Pesik resha (undesired but inevitable outcome). This occurs when a permitted act will inevitably and directly lead to a prohibited outcome. As an example, the Talmud stated that if one cuts off the head of a chicken on Shabbat to play with the head, even though one does not care if the chicken lives or dies, a biblical violation has occurred since the action will inevitably lead to killing an animal (a biblical prohibition on Shabbat).
- Davar she'eino mitkaven (unintended act). This is identical to a pesik resha except that the second act might not occur, and is thus permitted. An example is dragging a chair across a dirt floor. There is a biblical prohibition to plow a field, but since dragging a chair will not for sure lead to creating indentations in the ground, it is therefore permitted.
- Pesik resha delo nichah lei (undesired outcome with no benefit). This is a pesik resha where the outcome, even though it must occur, will provide no benefit to the person causing it.
