Fun Fact

Fun Fact: The term “keyless” comes from early electrical fixtures that used key-operated switches – keyless fixtures were the simple alternative! The first keyless fixtures were developed in the 1880s and were essentially just lamp sockets. Some keyless fixtures have been in continuous operation for over 50 years due to their simple, reliable design. Interestingly, keyless fixtures are making a comeback in smart homes where external smart switches provide more control options than traditional integral switching!
