Schweitzer Engineering Laboratories (SEL) was founded in Pullman in 1982 after Dr. Ed Schweitzer invented the first microprocessor-based digital relay while completing his doctoral research at Washington State University (WSU). The company has grown significantly over the past four decades and now employs nearly 8,000 people worldwide. SEL products are used in 174 countries.

SEL has been a long-time supporter of the Pullman Chamber and has been an active participant on the Chamber Board of Directors and the Government Affairs Committee for many years. The company values the important role Chambers play in civic engagement and in teaching and advocating for economic and political freedom on behalf of members.

Even with global growth, SEL and its employees remain deeply committed to Pullman. Nearly 3,000 employees work at the company headquarters. In 2026, SEL is celebrating several major milestones, including the purchase of the Pullman Aquatic Center in January, now renamed the Schweitzer Wellbeing Center. This summer, the company will share more about the newly formed medical devices team. Later this fall, Washington State University will open WSU Schweitzer Engineering Hall, made possible through a $20 million gift from SEL and Dr. and Ms. Schweitzer.

SEL employees will continue to support local nonprofits through personal giving and volunteer service in schools and at STEM events. The company also plans to continue hiring WSU interns and graduates each year, along with broader hiring to meet increasing global demand from electric industry customers.
