Supco L290 Limit Switch Snap Disc 250°F-290°F Cut-In/Out

The Supco L290 Limit Switch manages high-temperature circuit switching in HVAC systems through a snap-disc mechanism calibrated between 250F and 290F. The temperature-sensitive disc changes its electrical contact position when the monitored temperature reaches the specified switching threshold, allowing the connected control circuit to respond automatically. The switch is secured at the designated high-temperature sensing position and connects directly to the compatible equipment wiring. High-temperature switching maintains controlled circuit response, supports protection of connected components, and keeps heating equipment operating according to its set thermal limits.
