Key Features

This limit switch includes a separate metal pull‑ring assembly for mechanical contact switching. It boasts a long mechanical service life and is designed to withstand high-frequency repeated triggering typical of elevator door mechanisms.

Installation Guidelines

During replacement, wire terminals must be thoroughly inspected. After installation, manually test the pull‑ring trigger and reset function to verify contact logic, followed by complete door-opening and closing tests. Secure mounting is essential to prevent displacement caused by vibration, thereby avoiding poor connections and false alarms while ensuring safe and stable operation of the elevator door circuit.
