From our beginning over 60 years ago, Carson Manufacturing Co., Inc. has worked endlessly pushing the far reaches of technology to design innovative solutions that exceed the needs of our customers. We first got started when founder Harold Carson designed, patented and began manufacturing a new variable speed motor control for the HVAC industry. That design later lead to the development of our current line of rotary switches. Over the years, our teams of engineers have designed and patented several other technically advanced components used in products including transformers, electronic voting machines, high fidelity sound systems, electronic sirens, A/V programmers and remote air control systems.
