# It is permitted to use an electric blanket on shabbat, provided one does not move the knob that adjusts it.  It is proper to place scotch tape on top of the knob in order to prevent oneself from accidentally adjusting the blanket on shabbat. <ref> Igrot Moshe 3.50, Menuchat Ahava 1.24.37, Yechave Da'at 2.49 </ref>

# It is forbidden to use a regular elevator on [[Shabbat]]. Some allow using a '[[Shabbat]] elevator' which stops at every floor, while others forbid, and some say one may go up in the [[Shabbat]] elevator but not down. It is forbidden to touch the elevator doors when they are closing. <ref>Shemirat Shabbat KeHilchata 23:29 permits uses a [[Shabbat]] elevator on [[Shabbat]]. Sefer Maliyot BeShabbat (chapters 1 and 7) holds that one may go up in the elevator but not down. Menuchat Ahava 24:15-6 concludes that one shouldn't use the [[Shabbat]] elevator to go up or down unless there is a great need in which case he is lenient to allow going up in the [[Shabbat]] elevator. Rav Yosef Henkin (Edut LeYisrael p. 121) rules that for someone who's weak to do a mitzvah such as daven with a minyan, one can be lenient to use an elevator on Shabbat as long as the non-jew is the one who presses the button and not a Jew. 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>
