Supco L190 Limit Switch Snap Disc 150°F-190°F Cut-In/Out

The Supco L190 Limit Switch regulated temperature circuit operation through a snap-disc mechanism calibrated for 150F to 190F switching. As temperature changes, the disc flexes at its calibrated threshold and changes the electrical contact position, controlling the connected circuit without continuous manual adjustment. The switch is mounted at the specified sensing point in HVAC systems and connects directly to the equipment control wiring. Defined thermal switching maintains controlled equipment response, supports temperature-based circuit protection, and keeps connected heating operations within the specified temperature range.
