Are different elevator button brands hard to replace?
In elevator maintenance and modernization projects, elevator buttons are among the components that fail most frequently and require the most frequent replacement. However, many maintenance engineers encounter the same problem: elevator button models from different brands are completely incompatible, making replacement extremely difficult!
There are many brands in the elevator industry, and button styles, sizes, wiring methods, working voltages, and frame structures all differ. Without fully understanding these differences, it is easy to encounter issues such as buying buttons that do not fit, mismatched plugs, unusable wiring, incorrect voltage causing the LED not to light or burning the circuit board, or inconsistent appearance that affects the overall aesthetics.
Today, the technical team from A-FLY Elevator & Escalator Parts Supplier will explain why elevator buttons are not interchangeable and how to easily solve replacement challenges.

1. Core Reasons Why Elevator Buttons Are Not Interchangeable
1. Each brand has its own structural standards
Every brand designs its buttons differently.
Differences include:
Frame dimensions
Panel thickness
Mounting structure (clip-on / screw-mounted / embedded)
Backlight module design
Therefore, a button from Brand A cannot be directly replaced with one from Brand B. This is the fundamental reason.
2. Wiring terminals and plug interfaces differ
Elevator button wiring types include:
Pin-type
Socket-type
Harness-type
Terminal screw-type
Different brands also define pin assignments differently. Random replacement may cause signal errors or even damage the main board.
3. Working voltage and light source standards vary
Common button voltages include:
DC 12V
DC 24V
AC 110V
AC 220V
Voltage mismatch may cause:
LED not lighting
Signal not transmitting
Severe cases: COP/LOP PCB damage
4. Functional logic varies
Such as:
Up/Down hall call indicator
Handicap button
Alarm button
Door Open / Door Close
Fireman operation button
Different brands use different logical programming, so the replacement must match perfectly to function.
2. Buttons Are Not Interchangeable, but Replacement Is NOT Difficult — The Key Is Choosing the Right Supplier
Even though different brands and models are not interchangeable, it does not mean the button cannot be replaced. You only need to do two things:
1. Confirm essential parameters
Before ordering, you must confirm:
Elevator brand and model
COP or LOP location
Button frame size
Plug type & pin definition
Working voltage
Button function (floor / DO / DC / alarm, etc.)
Light color & material requirements
The more accurate the information, the smoother the replacement.
