What Details Are Needed to Order or Replace Elevator Buttons?
Elevator buttons are one of the most frequently used components in an elevator, and also the parts that are most prone to wear, damage, and aging. When buttons become unresponsive, the light does not turn on, the touch feels abnormal, or the appearance is damaged, timely replacement is extremely important. However, during procurement or replacement, many customers often provide insufficient information, leading to mismatched models, incorrect dimensions, or wrong voltage.
To help you quickly and accurately find the correct elevator button model, A-FLY Elevator & Escalator Parts Supplier has prepared the most complete ordering guide for you.
The following will tell you:
What key information is required when ordering buttons, and why each item is important.

1. Confirm the model: Elevator brand, control system model, or button model
Different elevator brands use different button specifications and interfaces.
If you can provide the following information, the matching efficiency will be greatly improved:
Elevator brand
Control system model (such as NICE3000, STEP, BLT system, etc.)
Whether the button belongs to the COP or LOP
Different systems correspond to different materials, key modules, LED boards, and wiring methods.
This is the most important first step in choosing the right model.
2. Provide appearance photos of the button (front + back)
A clear photo is more accurate than any description—especially the back of the button, including:
Button module structure
LED board interface
Connector terminal shape
PCB board layout
LED positions
The model marking on the back of the button
Even buttons from the same brand may vary greatly between different production years.
The clearer the photo, the faster the matching.
3. Confirm the installation hole size
Each button must be installed onto the panel, so the hole diameter determines whether installation is possible.Common hole sizes include 32mm, 36mm, 42mm, 46mm, or customized openings.If the hole size does not match, the button cannot be installed or will be loose and fall off.You should measure:
Opening diameter
Panel thickness
Outer frame size of the button (round or square)
4. Confirm the button operating voltage
The lighting voltage of the elevator button must match the system; otherwise:
Too high → burns instantly
Too low → light does not turn on
Wrong wiring → button cannot trigger signal
Common voltages include DC 12V, DC 24V, and occasionally AC 110V or AC 220V (mainly older elevators).If you are not sure, A-FLY can determine the voltage based on the control system.
5. Confirm the button function type
Different functions correspond to different internal structures and wiring methods.Please confirm whether the button is used for:
Floor selection buttons (1F, 2F, 3F…)
Up/Down call buttons
Door Open (DO)
Door Close (DC)
Alarm (ALM)
Fireman’s button
Card reader / accessibility / emergency functions
Touchless sensor button
Each function uses different modules and cannot be mixed.
6. Confirm light color and material requirements
Many projects require unified appearance. You may specify:
Light color (white, blue, red, dual-color)
Button material (stainless steel, acrylic, glass)
Button shape (round/square)
Whether braille is required
Whether custom labeling or LOGO is needed
A-FLY supports OEM/ODM customization to meet various elevator decoration styles.
7. Confirm whether the installation position is COP or LOP
COP (Car Operating Panel) and LOP (Landing Operating Panel) buttons differ in usage environment:
COP → more functions, more complex structure
LOP → more durable, anti-vandal, brighter
The LED board and connectors between the two are often not compatible, so the location must be confirmed.
