Firestat Limit Switches
Duct high limit switches are straightforward devices, leaving little room for differentiation among competitors. However, as you’ll notice, our pricing consistently outperforms that of our rivals. This is primarily because our switches exclusively function as limit switches, whereas many similar switches also double as fan switches. This allows us to offer more competitive pricing for customers who don’t require a fan switch.
If you can’t find your part number listed, feel free to contact our direct support. Simply provide your switch or application requirements, and one of our customer service representatives will be glad to assist you!
