The revolutionary new Zman Switch, developed and distributed by Zman Technologies, has already been installed in the homes of leading rabbanim and halachic authorities, the company announced. Zman Switch is the first of many new technological products that the company is developing to help frum Jews conform to the highest standards of halachah, particularly shemiras Shabbos and yom tov, and to meet the needs of the specific lifestyle of shomrei Torah u’mitzvos.

Amongst the rabbanim who endorsed the new technology developed by Zman Technologies are Rabbi Yecheskiel Roth, rosh beth din, Karlsburg; Rabbi Yisroel Belsky, posek, Orthodox Union (OU); Rabbi Moshe Shaul Klein, member of the Beth Din of Harav Wozner in Eretz Yisroel; Rabbi Hershel Schachter, rosh yeshiva, Rabbi Isaac Elchanan Theological Seminary (Yeshiva University; Rabbi Menachem M. Weissmandl; Rabbi Usher Eckstein, member of the Badatz of Belz; and Rabbi Boruch Lesches, rav of K’hal Tzemach Tzedek Lubavitch. Many of the rabbanim are already using the trailblazing technology in their homes. It will be available in coming days in local hardware, appliance, electrical-supply, and Judaica stores.

Zman Switch is built with a foolproof, patented program, approved by rabbanim and tested by experts. The switch, which also serves as a regular timer during the week, replaces most regular light switches and can be installed in minutes. Select one of the many Jewish communities throughout the country in the advanced LED screen, and the switch automatically configures the start of Shabbos in the location and allows the user to preset the desired time for when the light should go on each week (e.g., 20 minutes before candle-lighting time). The user can also preset the switch to go on and off during Shabbos at preset times, eliminating the need for the common weekly adjustments. The Shabbos and yom tov zmanim in each location are already calculated until the year 2050.

The feature that most intrigued the rabbanim was that once the timer is in Shabbos mode, it cannot be switched on or off (save for an emergency bypass, for Hatzalah, for example), eliminating the need for tape, Velcro, and guards to protect against accidentally triggering the switch. Many a household has experienced the discomfort of sitting in the dark at a Friday-night meal as a result of the inadvertent turning off of lights on Shabbos. The rabbanim were enamored with the cutting-edge technology which will ultimately enhance shemiras Shabbos in the frum home and eliminate some of the complex problems that are inherent in using electric lights.

Rabbi Tzvi of Ortner of Halachic Tech USA, who serves as halachic consultant to Zman Technologies, said that the “enthusiastic universal endorsement of halachic authorities is unprecedented and clearly indicates how the new technology is a game-changer for observant Jews.” Zman Tech can be found online at www.zmantechnologies.com. v
