A furnace changeover switch is a vital component designed to isolate and alternate between two separate furnace systems. This allows for:

• Uninterrupted Operation: By enabling the switch to one furnace while the other undergoes maintenance or repair, you can maintain production flow without downtime.
• Enhanced Safety: Isolating a furnace during maintenance or repairs ensures the safety of technicians working on the inactive unit.
• Load Balancing: In applications with multiple furnaces, a changeover switch can distribute the workload, promoting efficient energy use.

These switches are typically found in industrial settings and are built to handle the high currents associated with furnace operations.
