KONE Elevator Spare Part – Door Lock Contact Switch (Auxiliary Door Lock) KF-9074 Imported, Brand New

The KF-9074 is a door lock contact switch originally designed by Selcom Wittur and is widely used as a landing door and car door auxiliary safety contact for KONE 3000 series elevators. Rated at 230V and 2A, it features a red bakelite flame-retardant housing with a pin-type contact structure.

As a vital safety component, the switch monitors whether the elevator doors are fully locked. It breaks the safety circuit whenever the door lock is not engaged, preventing the elevator from running and protecting passengers. After millions of repeated door cycles, contact ablation or poor connection may occur, triggering elevator stop and door fault alarms. This makes the KF-9074 a common replacement spare part for passenger elevators in residential buildings, hotels, and commercial complexes.
