Boltswitch, Inc., a subsidiary of Socomec, is a long‑standing North American manufacturer specializing in fusible bolted pressure contact switches and fusible pullout switching solutions. Founded in 1953 and based in Crystal Lake, Illinois, the company has built its reputation on durable, UL‑listed switching equipment designed for demanding industrial and high‑fault‑current applications.

Boltswitch offers a comprehensive product range with ampere ratings from 30 up to 6000 amps, serving applications across service entrance equipment, double‑throw manual transfer switches, live‑front and dead‑front disconnects, transit switches, and a variety of specialized power‑circuit devices. Their switches were among the first to pass UL testing at 600 volts, and the company pioneered notable innovations including Quick‑Make/Quick‑Break operators and early Shunt‑Trip mechanisms, reinforcing its commitment to industry‑leading safety and performance.

Now part of the Socomec family, Boltswitch continues to deliver robust and reliable switching solutions trusted throughout the electrical industry.
