Holmes & Co. | known_for = Developing technology behind the modern light switch }}John Henry Holmes (1857-1935) was an English electrical engineer, inventor, Quaker and pioneer of electric lighting who invented the quick break light switch, the technology behind which remains the basis for modern wall mounted light switches.[1] CareerIn 1880, Holmes attended a public demonstration of Joseph Swan's incandescent light bulb. This seemed to spark his interest in electric lighting, and he approached Swan on multiple occasions in hopes of becoming his apprentice.[2] John Henry Holmes and his brother Theodore, also a Quaker, founded J. H. Holmes & Co. in Shieldfield, Newcastle upon Tyne in 1883, their manufacturing company specializing in early motors, dynamos,[3][4][5] switches, and lighting. The company was very active in the early proliferation of electric lighting, having installed Newcastle's first domestic electrical lighting into their father's house, and supplied installations throughout Europe and the British colonies,[6] making deals in the United States as well.[7] John Henry Holmes invented the quick break light switch in 1884.[8] which was patented in Great Britain [9] and the United States [10] that year. The technology augmented the standard switch by ensuring the internal contacts moved apart quickly enough to deter the electric arcing that created a fire hazard and otherwise invariably shortened the switch's lifespan.[11] The quick break technology remains in use in domestic and industrial light switches modern times.
