The first electric light switch, invented by British engineer John Henry Holmes in 1884, was a simple key-type design that allowed safe control of electric lights, reducing fire hazards from gas lamps. This innovation not only sparked the modern electrical era but also influenced over 100 billion switches produced annually today, fundamentally shaping everyday convenience in homes and industries.
