Overview
Heavy-duty safety switches provide a highly visible means of disconnect to help improve personnel safety and equipment protection. Additionally, they’re Ideal for applications where reliable performance, safety, and service continuity are critical.
Heavy-duty safety switches Applications
For heavy commercial and industrial applications where reliable performance and service continuity are critical. For the toughest heavy commercial and industrial applications, refer to Page V2-T1-77 for catalog information on our mill-duty safety switch. 316 Grade stainless steel is often a desirable choice for wastewater treatment plants and petrochemical facilities.
