Quality Switch is a family owned and operated company that is transitioning to the third generation. Quality Switch has been actively involved in the transformer industry since the 1950’s when the founder, Horace Sewell, started making switches inside of his machine shop, Quality Machine, for the Standard Transformer Company in Warren, Ohio. The switches were initially designed for distribution transformer applications. The company continued to grow and in 1974, the switch business was incorporated as a standalone entity and also moved the focus to include power transformers as well.
