Inspection / normal switch (NO)
LA137-BD21
The elevator pit buffer switch lxp1-3SE3-020-1a is a limit switch used near the lift pit to sense when the car reaches the buffer area. Its job is to send a clear signal to the controller so the system can stop movement during checks or when the car rests on the buffer. This switch is made for steady use in lift pits where dust, moisture, and vibration are present. It supports safe inspection work, helps confirm buffer contact, and ensures that the lift responds correctly during maintenance or fault conditions. Its simple contact action and secure mounting design make it suitable for many lift models used in the region.
