A History of Setting the Standard by Which Others Are Measured

As the world leader in vacuum contactors, starters and controllers, we are dedicated to continually raising the bar for industry standards of in life safety and fire protection.

Dating back to the 1920’s, Joslyn Clark began as the Clark Controller Company. Instantly recognized as a pioneer of innovation and quality, Clark products were recognized for their advanced design and reliability. And although the name has changed a couple times over the years, the one thing that hasn’t is our commitment to excellence and unrivaled safety and reliability.

We currently maintain a state-of-the-art modern manufacturing facility in Elizabethtown, NC. Our long history of loyalty and commitment is reflected in our employees, many of whom were on the original development team for some of our products, and are still with us today as we continue to refine and implement new improvements and innovations every year. This culture of low turnover and long-term dedication is one of the ways we’ve been able to build and incorporate so much innovation and long-lasting quality into our products.

With a dedicated distributor channel throughout the world, the Joslyn Clark brand is renowned across the globe for our superior quality, unbeatable value and impeccable customer service.
