LHB-008A Elevator Hall Call Button PCB Board LED Illuminated Landing Push Button Lift Operation Replacement Spare Parts

LHB-008A is the original landing call button circuit board for Mitsubishi passenger elevators. It is installed on each floor landing operating panel, equipped with high-brightness LED indicator light and stable micro-contact switch. The flame-retardant small PCB board features anti-surge circuit design, strong anti-electromagnetic interference, and stable signal output. Standard size and wiring interface allow direct replacement without modifying the original landing panel, compatible with mainstream Mitsubishi elevator control systems.

• Send Floor Call Request Signals
  Passengers press the button to send upward or downward landing call signals to the elevator main control board, so the system arranges elevator arrival scheduling.
  Call Receiving LED Indication
  After the mainboard receives the call command, the LED light stays on to remind passengers the call has been registered successfully. The light turns off automatically when the elevator arrives at this floor.
  Stable Human-Machine Interaction Module
  As basic landing operation component, it realizes convenient signal interaction between waiting passengers and elevator control system, improving user riding experience.

Elevator Push Button – FAQs

Q1: Are elevator push buttons universal?
No. Elevator push buttons differ in mounting dimensions, electrical contacts, illumination voltage, connector design, and required functions.

Q2: What is the difference between mechanical and touch-sensitive elevator buttons?
Mechanical buttons use a physical actuation mechanism, while touch-sensitive buttons detect an input without conventional mechanical travel. Their electrical interfaces and application requirements may differ.

Q3: Can an elevator push button be replaced without changing the complete operating panel?
In many panel designs, an individual button can be replaced if a compatible part is available. The electrical connection and mounting configuration must be checked.

Q4: Why does an elevator push button light up but fail to register a call?
Possible causes include contact faults, wiring issues, input circuit problems, or controller-related faults. Illumination alone does not confirm that the call signal is functioning.

Q5: What specifications are needed to identify a replacement elevator button?
Please provide the original model, mounting dimensions, contact type, illumination voltage, connector photos, and required symbol.
