The Hobbs name is well known world-
wide for the development of quality
electro-mechanical products. The
invention of the first electrically
wound automobile clock in 1938
created what is now known as Hobbs
Corporation. John Weston Hobbs
was the inventor that cultivated this
electrically-wound vehicle clock
into a company that has over the
years expanded to include hour
meters, pressure and vacuum
switches, halogen lamps, transmission
shifters, and other custom electro-
mechanical products. Hobbs’ broad
customer and market base includes
industries such as automotive,
agricultural, material handling,
construction, marine, medical, heavy
truck, lawn and garden, recreational,
generators, compressors and
aviation. Hobbs’ commitment to
continuous improvement and total
quality management will allow for
fur ther expansion of its product lines
and customer base while maintaining
the highest standards of excellence.
