Keeping the Sabbath Dark

Jonathan Whitman received patent 6,974,925 for a Jewish Sabbath Switch Cover that prevents Jews from accidentally turning on lights during the Sabbath, when it is forbidden for Jews to do so. The cover mounts with adhesive film. The Sabbath Switch Cover can be used to selectively disable or enable the internal lighting system of most major kitchen appliances in order to assist in keeping the Jewish Sabbath and Holidays, and it is easily manufactured, inexpensive to produce and purchase, and convenient to apply and use.
