Description
The Marley Engineered Products L120-25F Limit Switch (part number 4520-2024-000) is a precision OEM safety control component engineered for use in Marley electric heating equipment. Limit switches are a critical line of defense in any heating system, automatically interrupting the circuit when operating temperatures exceed a safe threshold — protecting both the equipment and the surrounding structure from overheating damage.
Product Overview
Designed as a direct OEM replacement, this limit switch is built to Marley’s exact specifications, ensuring reliable fit and function in compatible Marley heater models. The L120-25F designation indicates a 120°F setpoint with a 25°F differential, meaning the switch opens at 120°F and resets once temperatures fall back to a safe level — providing automatic, self-resetting protection.
