What Are the Common Voltages Used for Elevator Buttons?
In an elevator system, the elevator button is one of the most basic yet frequently used control components.Whether on the car operating panel or the landing call box, it serves as the input and signal transmission interface between passengers and the control system.The voltage used in these buttons not only affects signal stability but also determines system compatibility and safety.
Today, A-FLY Elevator & Escalator Parts Supplier explains the common voltage types for elevator buttons and their application scenarios.

1. Basic Concept of Elevator Button Voltage
An elevator button is essentially a low-voltage control switch that sends a signal to the main control board by opening or closing a circuit.
Its working voltage depends on the design of the control system — different voltages correspond to different signal logic and operating environments.
Common elevator button voltages include:
DC12V (Direct Current 12V)
DC24V (Direct Current 24V)
AC110V / AC220V (Alternating Current)
Among them, DC12V and DC24V are the most widely used standards in modern elevator systems.
2. Common Voltage Types and Their Features
(1) DC12V Elevator Buttons
The DC12V standard is a safe, low-voltage control mode often used in modern smart elevators, residential buildings, and low-power control systems.
Key features:
Stable voltage and low power consumption
Minimal electromagnetic interference — ideal for sensitive control systems
Excellent compatibility with LED backlight circuits
Safe maintenance, preventing high-voltage electric shock risks
A-FLY’s 12V elevator button series is widely used in smart elevators worldwide, offering sensitive response, soft illumination, and customizable language and logo options.
(2) DC24V Elevator Buttons
The DC24V model is currently the most common standard in elevator control systems.
It is compatible with most major elevator control systems, including Monarch NICE3000, STEP, BL6, STEP8000, and others.
Main advantages:
More stable signal transmission and stronger anti-interference capability
Supports long-distance signal communication
Compatible with various display boards and power modules
Suitable for high-rise and heavy-load elevator systems
A-FLY’s 24V Elevator Push Button Series features high-sensitivity contacts and integrated LED modules, ensuring long service life and strong compatibility — an ideal choice for maintenance and modernization projects.
(3) AC110V / AC220V Elevator Buttons
Some older elevators or specific control systems still use AC voltage, typically AC110V or AC220V.
For example, older Japanese models or legacy control cabinets often adopt this standard.
While AC buttons offer stronger driving power, they are gradually being replaced by safer low-voltage DC systems in modern elevators.
However, A-FLY continues to supply compatible AC button solutions for customers engaged in old elevator refurbishment projects.
3. Importance of Voltage Matching
Incorrect voltage matching can lead to several issues:
Button light malfunction (flickering or no illumination)
Signal transmission failure, causing call button inoperability
Control board damage from overvoltage or mismatched current
Therefore, when purchasing or replacing elevator buttons, it’s crucial to match the voltage specifications with the elevator’s control system and power output.
A-FLY provides technical guidance and voltage matching services to ensure full safety and compatibility.
