Description
The Supco L205 -40F Limit Switch is a snap-action temperature control component used in compatible heating and cooling systems to regulate equipment operation based on internal air or surface temperature. Installed in HVAC systems, it opens or closes an electrical circuit when a preset thermal threshold is reached, typically to protect components from excessive heat conditions. It is commonly used in residential and light commercial furnace and air-handling applications where automatic thermal cutoff control is required. It supports temperature-based circuit interruption, assists in controlling operating cycles, and maintains stable and secure equipment performance during normal operation.
