Supco SRL220 SPST M/R Rollout Switch 220°F

The Supco SRL220 Manual Reset Rollout Limit Switch is a single-pole, single-throw thermal control part used in HVAC systems to open its contacts when the temperature hits 220°F to interrupt electrical current flow to prevent heat accumulation. It used a temperature-sensitive part that is adjusted to a specific point to guard burners, heat exchangers, and other parts against overheating. This rollout switch is installed in the control circuit of the system in areas where heat can be concentrated, and improves the operational safety, reduces other parts, and is used to ensure operation in residential and commercial heating systems.
