Push button switches play a vital role in elevator and escalator applications. Their main applications include:
Floor selection and navigation:
Buttons in elevators are often used to select the floor you want to reach. These buttons are designed to withstand continued daily use and are often tightly integrated with the elevator’s control system.
Buttons are often equipped with backlights or indicator lights to ensure they are clearly visible even in low light conditions.
In order to improve the user experience, these buttons may be displayed simultaneously with the floor indicator screen in the elevator to increase intuitiveness.
Door control functions:
There are usually buttons inside the elevator that control the opening and closing of the doors. These buttons may include the option to keep the door open, especially when loading and unloading cargo or if more time is needed for entry and exit.
Some elevators may also be equipped with buttons to accelerate door closing, for use during busy periods or emergencies.
Emergency and safety features:
Elevators often have emergency call buttons that are used to communicate with building security personnel or outside services in the event of a malfunction or if passengers require assistance.
Some elevators may also be equipped with other safety-related buttons, such as overload warnings or emergency stops.
Accessible Design:
The button design should fully consider the use needs of people with disabilities. They are usually designed to be larger and lower in order to be easily accessible by wheelchair users and others.
Buttons may have braille markings or voice prompts to help passengers with limited vision identify and use them.
Escalator control:
Escalators may have control buttons at the start and end points to start or stop the escalator when necessary.
These buttons are usually designed to be easily identified and operated to ensure safe use.
Status and indicators:
Buttons may be equipped with status lights, such as a green light to indicate that the elevator or escalator is available, or a red light to indicate that it is under maintenance or unavailable.
Status indicators are important to guide users on the correct use of elevators or escalators, especially in high-traffic public spaces.
Maintenance and service operations:
Maintenance and service personnel may use dedicated buttons to place the elevator into specific maintenance or inspection modes.
These buttons are usually hidden in service panels inside the elevator and are not accessible to regular passengers.
Environmental adaptability:
Elevator and escalator buttons need to be able to adapt to different environmental conditions, such as high humidity, temperature differences or vibrations.
The material and design of the buttons need to meet standards for long-term durability and resistance to wear and tear.
User experience and aesthetics:
The buttons are also designed with user experience in mind, with good tactile feel and quick response.
The exterior design is usually coordinated with the building’s interior to maintain an overall aesthetic appearance.
Push button switches used in escalators need to comply with a series of safety standards and specifications to ensure operational safety and equipment reliability.
International standards: such as those provided by ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission). For example, ISO 18738 defines measurement methods for elevators and escalators, while IEC 60947-5-1 deals with specifications for control circuit equipment and switching elements.
European standards: For example, the EN 81 series of standards, especially EN 81-20 and EN 81-50, which provide safety rules for the design, manufacture and installation of elevators.
North American standards: Such as ASME A17.1/CSA B44, which is the safety standard for elevators and escalators in the United States and Canada.
Electrical safety: Ensure that electrical components, including push button switches, comply with applicable electrical safety standards, such as UL or CE certifications, which ensure the safety and reliability of electrical products.
Environmental adaptability: The push button switch should be able to withstand long-term use and various environmental conditions, such as temperature changes, humidity, vibration and humid environments. In this regard, IP (Protection Level) rating standards (such as IP65 or IP67) are an important indicator of dustproof and waterproof capabilities.
Accessibility Standards: Push button switches should be easily usable by individuals with disabilities in accordance with the ADA (Americans with Disabilities Act) or other similar accessibility standards.
Vandal Resistance and Durability: In high-traffic use areas, push button switches should have a vandal-resistant design and high durability to handle the wear and tear that comes with frequent use.
Emergency stop and safety features: Emergency stop buttons should meet specific safety standards and be able to respond quickly and stop the escalator in an emergency.
How to ensure long-term durability of escalator button switches?
Designed to withstand thousands of operations, these buttons are constructed from wear-resistant materials and specially designed for structural strength.
How do escalator buttons ensure safety in emergencies?
The emergency button is designed to respond quickly and stop the escalator quickly. Some designs also include protection against accidental operation.
How do buttons adapt to the needs of people with disabilities?
Button designs include larger sizes, braille markings, voice prompts, etc. to make them easier for people with disabilities to use.
What is the maintenance and replacement process after the escalator button is damaged?
Typically handled by professional technicians, they are designed to be easily accessible and replaceable to simplify the maintenance process.
How do buttons adapt to different environmental conditions?
By using appropriate materials and sealing techniques, the buttons are ensured to work stably in a variety of temperature, humidity and vibration conditions.
What are the technical specifications and functions of push button switches?
Including voltage, current carrying capacity, mechanical life, etc., functions may include lighting indicators and tactile feedback.
How do buttons comply with safety standards and regulations?
Design and manufacturing must comply with relevant international and regional safety standards such as ISO, IEC, EN or ASME.
