Elevator Push Button Failures & Solutions
In an elevator system, elevator push buttons are the most direct interface between passengers and the equipment. They are also among the most frequently used components and, consequently, one of the parts with the highest failure rates. Once a button fails, it not only affects passenger experience but may also lead to incorrect operation, frequent service calls, and even impact normal elevator operation.
As a professional elevator & escalator spare parts supplier, A-FLY has summarized the most common causes of elevator button failures and provides practical solutions based on extensive maintenance and modernization project experience.
1. Common Symptoms of Elevator Button Failure
In daily operation, elevator button issues usually present as:
No response when pressed; floor commands cannot be registered
Indicator light does not illuminate or stays on continuously
Slow or delayed response, requiring repeated pressing
Button sticking or poor rebound
Repeated failure of a specific floor button or button row
These issues are typically the result of long-term wear rather than sudden failure.
2. Main Causes of Elevator Button Malfunction
1. Worn or Oxidized Contacts
Traditional mechanical buttons experience frequent high-cycle use. Over time, internal contacts may wear, oxidize, or burn, resulting in poor electrical contact—this is the most common failure cause.
2. Internal Mechanical Wear
Spring fatigue or deformation of plastic components can cause insufficient travel or failure to reset, leading to “hard to press” or “no response” issues.
3. Indicator Light or LED Board Failure
Aging LED boards or circuit damage may cause the indicator light to stop working. In some cases, the command is registered, but users mistakenly believe the button has failed.
4. Voltage or Signal Mismatch
Different elevator systems use different button voltages, such as DC 12V or DC 24V. Incorrect voltage or incompatible signal types can cause unstable operation or premature failure.
5. Loose Wiring or Aged Cables
Long-term vibration may loosen terminals, while aging cables—especially in older elevators—can cause intermittent or unstable signals.
6. Environmental Factors
Moisture, dust, or cleaning liquid ingress can accelerate contact corrosion and reduce service life. This is especially common in underground parking garages and coastal environments.
3. Potential Risks of Ignoring Button Failures
If button problems are not addressed in time, they may lead to:
Passenger complaints due to perceived elevator malfunction
Incorrect operation affecting elevator logic
Increased maintenance costs due to repeated single-button replacement
Failure during safety inspections or annual certification
Therefore, button failure is not a “minor issue” but a key factor affecting overall elevator reliability.
4. Effective Solutions for Elevator Button Failures
1. Evaluate the System as a Whole
If multiple buttons begin to fail, it is recommended to replace the entire button set or the COP / HOP panel rather than repairing individual buttons repeatedly.
2. Choose High-Quality, Long-Life Buttons
Premium elevator buttons feature durable contact structures, stable LED light sources, and reliable sealing designs, significantly extending service life.
3. Confirm Voltage and Interface Compatibility
Before replacement, always verify working voltage, wiring configuration, and signal type to ensure compatibility with the existing control system.
4. Consider Upgrade Options
For modernization projects, upgrading to touchless or non-contact elevator buttons can greatly reduce mechanical wear and long-term maintenance frequency.
