“You shall not kindle fire in any of your dwellings on the Sabbath day” (Sh’mos 35:1—3). Ever since the light bulb was invented in the 19th century, the use of electricity on Shabbos and yom tov was never a simple matter. Shomrei Shabbos have resorted to various tactics to prevent inadvertently violating the Torah’s prohibition of kindling a flame on the holiest day of the week. Scotch tape, Velcro, even superglue (for the ultra-frustrated) have all proven less than effective in avoiding the prohibited “flip of a switch.” Individual timers for electrical appliances have remained an imperfect solution, with their constant need of adjustment and easy access for toddlers. Even modern-day “Sabbath modes” are problematic to many rabbanim who specialize in dealing with the complex world of electricity on Shabbos.

In a technological breakthrough that will protect the sanctity of Shabbos and yom tov, Zman Technologies has developed a new light switch that will change shmiras Shabbos and yom tov forever. This revolutionary invention is the simplest, most convenient, and most efficient way to safeguard the kedushah of Shabbos.

Zman-Switch is built with a foolproof, patented program, approved by rabbanim and tested by experts. All you need to do is install the switch and enter your preferred settings and current location. Zman-Switch will automatically calculate the proper zmanim for the entire year, eliminating the need to fiddle with it every single week. Throughout every Shabbos and yom tov, Zman-Switch adjusts the lights according to the preprogrammed settings, and it is impossible to accidentally switch the lights on or off. For an emergency, Zman-Switch has a special emergency override.

Mr. Yonason Bloch, who created Zman-Switch with Zman Technologies, an advanced science and technology firm, is a software expert and has an extensive background in military and private sector programming. “In Yiddishkeit, every issur has a safeguard,” says Mr. Bloch. “But when it comes to Shabbos and electricity, there are no safeguards–just fires everywhere. I created Zman-Switch to fill this pressing need.”

Zman Technologies has been universally embraced by a cross section of rabbanim and poskim as a major solution to an age-old problem. Their exceptionally warm letters of endorsement focus on the new device’s contribution to observance of Shabbos and yom tov. They concur that the Zman-Switch meets the highest standards of avoiding tampering with electricity on Shabbos. This is the first time that a product of this nature has received such broad support from rabbanim of all backgrounds. The rabbanim who have enthusiastically welcomed the product include R’ Yisroel Belsky, R’ Yechezkal Roth and his beis din, R’ Menachem Meir Weissmandl, R’ Moshe Shaul Klein, R’ Hershel Schachter, and R’ Usher Eckstein.

Zman-Switch is expected to hit the market in early August–just in time for yom tov–and will be available in all major hardware and Judaica stores nationwide. v
