He then says one doesn't need to protest someone who is lenient if the non-Jew is pressing the button, but a pious person (baal nefesh) would be strict. </ref> | # It is forbidden to use a regular elevator on [[Shabbat]].

* Rav Shlomo Zalman Auerbach (Minchat Shlomo 1:10) permits opening the refrigerator at any time because completing the circuit to run a motor may not involve any melacha at all, and even if it is, it is permitted because it is grama. He says that he’s not sure that it should be considered a psik reisha d’lo nicha lei as one doesn’t want the hot air to cause the motor to run sooner, because one also does want the motor to run so that the food doesn’t spoil. Tzitz Eliezer 8:12:4, 12:92, Rav Moshe Feinstein (quoted by The Shabbos Home vol 2, p. 482; see, however, Igrot Moshe 2:68), Rabbi Mordechai Willig (“Halacha Engages Modernity Part 8,” min 18-22), Rav Benzion Meir Chai Uziel in Piskei Uziel 15, and Rav Joseph B. Soloveitchik quoted by Rav Aharon Lichtenstein (http://www.daat.ac.il/daat/english/journal/broyde_1.htm) agree. Rav Willig commented that the minhag in America is to be lenient. | * Rav Shlomo Zalman Auerbach (Minchat Shlomo 1:10) permits opening the refrigerator at any time because completing the circuit to run a motor may not involve any melacha at all, and even if it is, it is permitted because it is grama.

* In defining grama, Rav Hershel Schachter (“Electricity on Shabbos,” min 73-6) explains that according to many achronim who understand grama as a delay in time, it isn’t even a psik reisha to open a refrigerator if the motor will turn on at a later time, while according to Rav Soloveitchik, who defined grama as a total disconnect in action, if it was certain that opening the door would cause the motor to go on any earlier, perhaps it would be forbidden to open the door when the motor wasn’t running based on koach achar m’urev bo. (See B’Ikvei HaTzon siman 7). | * In defining grama, Rav Hershel Schachter (“Electricity on Shabbos,” min 73-6) explains that according to many achronim who understand grama as a delay in time, it isn’t even a psik reisha to open a refrigerator if the motor will turn on at a later time, while according to Rav Soloveitchik, who defined grama as a total disconnect in action, if it was certain that opening the door would cause the motor to go on any earlier, perhaps it would be forbidden to open the door when the motor wasn’t running based on koach achar m’urev bo.

* On the other hand, Rav Ovadia Yosef (Yabia Omer 1:21) assumes like Rav Shlomo Zalman that it is grama, but thinks that completing a circuit may involve an issur deoritta of hav’ara. He also is uncertain if this should be considered a psik reisha d’lo nicha lei and concludes that it is permitted, but it nevertheless is proper not to open the door unless the motor is running. Har Tzvi 1:151, Menuchat Ahava 24:19, and Rav Henkin (Edut LeYisrael p. 122) agree that although it is permitted, it’s proper to be strict. | * On the other hand, Rav Ovadia Yosef (Yabia Omer 1:21) assumes like Rav Shlomo Zalman that it is grama, but thinks that completing a circuit may involve an issur deoritta of hav’ara.

* Lastly, Chelkat Yaakov O”C 76 argues that while it may be a psik reisha, perhaps it is not considered grama since this is the intended normal way it is used. Therefore, he rules that one may only open the door when the motor already is running. Minchat Yitzchak 2:16 and 3:24, Az Nidberu 2:36, Sh"t Igrot Moshe 2:68, 4:74, and Mishnat Rabbi Aharon 1:4 agree.

* [http://www.yutorah.org/lectures/lecture.cfm/742318/Rabbi_Mordechai_I_Willig/Halacha_Engages_Modernity_-_Part_8_-_Electrical_Appliances_(Part_1) Rabbi Willig (min 33-35)] says that using a water fountain on Shabbat depends on how long it takes for the motor to turn on. He mentions that one shouldn't use a water fountain which clearly will have the motor go on with a single regular use. However, he did not say this as a definitive ruling but in passing. | |||
* See [http://www.zomet.org.il/Eng/?CategoryID=253&ArticleID=143 Zomet.org] or [http://www.star-k.org/kashrus/kk-cooling-keepcool.htm star-k.org] for details on other problems with refrigerators. </ref> If one forgot to disable the light he is permitted to ask a gentile to open or close the refrigerator for him. <ref> Yalkut Yosef Chelek 4 Shabbat 5 page 229, Iggerot Moshe OC 2:68, and Shemirat Shabbat Kehilchatah 3:31. Rabbi Rieger in Hapardes 1934 volume 3 rules that one is even allowed to open up the refrigerator himself if he knows the light will turn on because it is a psik reishe dilo nicha leih but the aforementioned poskim all reject that opinion either because psik reishe dilo nicha leih is not permitted and they also argue that it is nicha leih because had it not been shabbat one would certainly want the light to help him see (see minchat shlomo page 91), and say that one should get a gentile to do it for him. [http://www.daat.ac.il/DAAT/english/journal/broyde_1.htm Rabbi Broyde and Rabbi Jachter] permit even asking a Jew who doesn't know that the light will turn on as this would fall under the category of mitasek. Iggerot Moshe OC 2:68 and Shemirat Shabbat Kehilchitah 31:1 also permit hinting to the gentile to disable the light so that the refrigerator could be used for the remainder of shabbat, but not telling him directly. </ref> | |||
# Some poskim permit walking in an area where a motion sensor will turn on a light provided that one does not intend to turn on the light if there’s no other way to walk. <Ref> | |||
* Sheivet HaLevi 9:69 permits walking in an area where there is a motion sensor that will activate a light, such as those attached to the outside of buildings. He explains that davar she’eino mitkaven refers only to when one does an action that may cause an unintended melacha. If, however, one is walking normally and makes no motion in order for a melacha to occur, it is not even a psik reisha as long as one’s intent isn’t to turn on the light. Orchot Shabbat (p. 79) quotes Rav Elyashiv and Rav Nissim Karlitz who say that since one doesn’t have a direct connection to the melacha and doesn’t care about the light, it’s not called melechet machshevet. The Shabbos Home (p. 489) agrees. | |||
* Rabbi Mordechai Willig (ibid. min 50-60) challenges this line of reasoning because it should be considered a psik reisha d’nicha lei and turning on a light might be deoritta. Furthermore, The 39 Melachos (p. 1215) says that if one can’t avoid walking in a place that will turn on a light because of a motion sensor and the streets are dark so that one will benefit from the light turning on, one shouldn’t leave his house! He does permit one to walk past such a motion sensor if he closes his eyes at the time when the light will turn on because in such a case then it is not considered niche lei, even if one will open one's eyes right afterwards. | |||
* On the other hand, Rabbi Hershel Schachter (ibid. min 62-8) explains that if one is doing an action that is physically disconnected from where the melacha is occurring, it isn’t considered a psik reisha. Thus, Rav Schachter says that there’s what to rely on to permit walking in an area where there is a surveillance camera or a motion sensor which will turn on a light as long as one doesn’t have intent to be videoed or turn on the light. </ref> | |||
# Many poskim permit walking in an area where there surveillance cameras will capture a person’s image as long as he does not intend to be recorded. <Ref> | |||
* Rabbi Mordechai Willig (ibid. min 48-49) agrees that it is permitted to walk in an area where there is a surveillance camera because unlike the light motion sensors, a person doesn’t benefit from the being videoed by the surveillance camera and thus qualifies as a psik reisha d’lo nicha lei which is permitted for a d’rabanan prohibition. Rav Shlomo Zalman Auerbach, (cited by Rav Zalman Nechemya Goldberg in Ateret Shlomo vol 6, p. 57), Yabia Omer 9:35, and The Shabbos Home (p. 489) agree. | |||

# Many poskim permit using an electrical automatic toilet if no other toilet is available. <Ref> | |||
* Rabbi Josh Flug (Sukkot To Go 5770, p. 27) writes that it is certainly permissible to use a toilet with an automatic flusher if no other restroom is available because most assume that using electricity is prohibited only d’rabanan and therefore is permitted for kavod habriyot. He says that perhaps it is even permitted if going to the non-automated toilets is inconvenient, since it may be a psik reisha d’o nicha lei on a issur d’rabanan. Practical Laws of Shabbat (Rabbi Rafael Soae, p. 335) agrees on the first point. | |||
* Rabbi Yisrael Belsky in Shulchan HaLevi 7:7 permits using this type of bathroom if there is no other bathroom available, but if there’s another option, he forbids using the electrical toilet. Rabbi Aryeh Lebowitz (“Using Automatic Bathrooms on Shabbos”) quotes Rav Belsky as saying that kavod habriyot would not be a leniency in order to wash one’s hands with an automatic sink. </ref> | |||
