Endorsements/Blessings
Confirming the Halachic permissibility for KosherSwitch® technology has always been one of our prime objectives. Since the early stages, when KosherSwitch® was only a dream, various rabbis, poskim, and Torah scholars have been actively consulted and have played a pivotal role in our undertakings. We have been fortunate that some of the world’s leading rabbis/poskim have made time to meet, analyze, and consult on the viability of our technology. We have secured dozens of endorsements, approbations, and blessings – some verbal, and others in writing – all as a result of extensive in-person demonstrations using our unique prototype and proof-of-concept units. Below are some of those we have already received. We are actively seeking additional approbations from key Torah scholars, and the conversion of verbal statements into written endorsements. See also the responsa section for a more detailed Halachic analysis of KosherSwitch®.
