🔒 Overspeed Governor Switch
Installed on the elevator governor, this normally closed safety switch is designed to detect overspeed conditions. Once triggered, it immediately cuts off the safety circuit, activates the brake, and brings the elevator to a safe stop—protecting passengers at the most critical moment.
🎯 Leveling Photoelectric Switch
Used to detect precise floor arrival, this sensor works on the photoelectric principle. When the elevator reaches the target floor, the light signal is blocked or reflected, converted into an electrical signal to ensure accurate leveling. Typically installed 4 pcs per car (top, bottom, left, right), with NO / NC types identified by label circuit diagrams.
✔ Reliable detection
✔ Accurate positioning
✔ Essential for safe and smooth elevator operation
