Description
The Supco L180-40 is a precision-engineered snap disc auto reset limit switch designed for dependable temperature control in a wide range of HVAC and appliance applications. With a fixed 140°F cut-in temperature and a fixed 180°F cut-out temperature, this limit switch provides consistent, repeatable performance to protect equipment from overheating and thermal damage.
The open-on-rise switch action means the contacts open when the sensed temperature reaches the 180°F cut-out threshold, interrupting the circuit and safeguarding downstream components. Once temperatures fall back to the 140°F cut-in point, the snap disc automatically resets, restoring normal operation without requiring manual intervention — minimizing downtime and service calls.
The snap disc mechanism delivers fast, positive switching action that eliminates contact chatter and ensures long service life. This unit is also cross-referenced as part number 60T11-610013, making it a reliable OEM-compatible replacement for a variety of heating systems, furnaces, and appliance controls.
