## Overview

The Shabbos Proof ZMAN Switch is a cutting-edge, micro-computerized timer pre-programmed with the entire Hebrew calendar through 2050. It automatically adjusts for sunset, sunrise, daylight savings, and Jewish holidays, including two-day Yom Tov and Rabbeinu Tam timing.

Designed for easy installation and intuitive use, it combines modern aesthetics with reliable, stress-free Shabbos observance and weekday energy savings.

## Description

ZMAN Technologies’ flagship product, the ZMAN Switch, has been dubbed the Next-generation Shabbos Timer. Designed by a former U.S. Air Force Weapons Systems developer, this product presents a brand new approach to an age-old concept. The easily installed ZMAN switch contains a micro-computer pre-programmed with the entire Hebrew calendar thru the year 2050, as well as candle lighting times and nightfall for any location across North America. Utilizing the device’s Set and Forget feature, the consumer or technician preforms a one-time location and preference selection. On and off preferences for Shabbos and Yom Tov are then permanently set, based upon candle lighting time or nightfall (choice of early ZMAN or 72-minute Rabbeinu Tam). After initial setup, there is never any need to revisit or re-adjust settings. The ZMAN switch is pre-programmed with all Jewish holidays, winter and summer clock changes, with additional customizable settings as per the consumer’s preference.The ZMAN switch’s easy-to-use interface makes settings and preferences adjustments simple and intuitive, even for the unskilled layman. In addition to enhancing the Shabbos, the ZMAN switch eliminates the Pre-Shabbos stress of fiddling with timers, and for the technically challenged, it ensures proper set times each and every Shabbos. Another vital breakthrough feature is the ZMAN Switch’s Shabbos-proof deactivation. Highly lauded by rabbonim, this feature eliminates accidental switch use on Shabbos, and will ensure that your light remains on or off as desired for the duration of the entire Shabbos. A simple Emergency Override feature will easily reactivate the switch in the event of a life threatening situation. With its sleek, unobtrusive, modern design and low-cost purchase price, the ZMAN switch is ideal for every light in the home. The device’s standard weekday settings make it an easy-to-use tool for weeklong, energy-saving home lighting automation.

## Customer Reviews

### ⭐⭐ Keep needing to reset after power blips
*by A***R on August 9, 2016*

Does what is described, but when we gave a power blip, it needs to be reset, which takes time to do and in NJ we have plenty of those

### ⭐ Great Idea, bad product.
*by A***R on January 19, 2015*

The zman timer is great idea, terrible executed. It takes a lot of time to program to individual use. The default setting is strange, like lights on in dining room on Yom Kippur and sukkot, and early off on seder night. After even the shortest power interruption, the volatile memory is gone, and the timer falls back to the default setting. One needs to reprogram from the beginning, and that about once a month.The timer need to be redesigned with a non volatile memoryAnother problem is that it max switching capacity is only 800 Watt (6.5 Amp) barely enough for a great chandelier and definitely not usable in a greater locale like a synagogue. The competition switched (Intermatic) 15 Amp.

### ⭐⭐⭐⭐⭐ Clever and convenient
*by O***0 on May 31, 2015*

Bought two, one for our kitchen and one for our dining room. Took a short time to program, fairly intuitive. The only weird thing was that I had to enter longitude and latitude for Ohio as it was one of the states missing from the location list. No problems after a month of use. It's convenient and gives me one less thing to think about when preparing for Shabbat or Chagim.
