Trane SWT1261 Limit Switch protecting the secondary heat exchangerThe Trane SWT1261 Limit Switch is a critical safety component designed for precise thermal regulation within residential furnaces. Engineered to replace the C340056P07 and SWT01261, this high limit control monitors the internal heat exchanger temperature to prevent overheating. Operating on an automatic reset logic, this thermal limit switch is factory calibrated to open the circuit when temperatures reach 260F and automatically close (reset) at 230F.
