Basic button structure

Panel
Elevator buttons are installed on the panel, which is usually made of plastic or metal. Plastic panels are more common because they are of lower cost and easier to process and install. Metal panels look more upscale and are often used in some high-end office buildings, hotels and other places. The main functions of the panel are to fix the buttons, provide a flat installation surface for the buttons, and also play a certain protective role, preventing dust, moisture and other substances from directly contacting the electronic components inside the buttons.

Button Body
Keycap: This is the outermost part of the button that people directly press with their fingers. Keycaps are usually round or square, with a certain curvature on the surface to conform to ergonomics and make it convenient for users to press. They can be made of materials such as plastic or rubber. Plastic keycaps are relatively hard in texture and have a shiny appearance; rubber keycaps feel soft and elastic, providing a better tactile sensation when pressed. The keycaps are usually marked with floor numbers, letters (used for special functions, such as "B" for basement) or symbols (such as open/close door symbols). These markings are either printed on the surface of the keycap by printing technology or fixed on the keycap by inlaying a sheet with the markings.
Button Housing: Located beneath the keycap, it is used to wrap and protect the internal mechanical or electronic components. It is generally made of hard plastic, with a shape and size that match the keycap. The design of the housing should ensure that the internal components will not be damaged during normal pressing and can provide stable support, enabling the button to maintain good performance during long-term use.

Trigger Mechanism
Mechanical Trigger:
There is a mechanical switch inside this type of elevator button. When the keycap is pressed, the keycap will push a mechanical connecting rod or plunger, causing the mechanical switch to close and thus generating an electrical signal. The mechanical switch is usually a microswitch, which is characterized by being small and sensitive. Inside the microswitch, there is an elastic metal sheet. When subjected to an external force, the metal sheet will deform and come into contact with another contact point, realizing the conduction of the circuit. The advantages of mechanical trigger buttons are simple structure, high reliability, and obvious tactile feedback when pressed, allowing users to know that the button has been pressed.
Capacitive Trigger:
Capacitive elevator buttons do not have a mechanical triggering part. They work by utilizing the capacitance characteristics of the human body. When a finger approaches or touches the keycap, the capacitance value between the human body and the capacitance sensing electrode inside the button will change. After the circuit inside the button detects this capacitance change, it will generate a triggering signal. The advantages of capacitive buttons are that their appearance can be made more beautiful. Since there are no mechanical parts, the keycap can be made very thin, and they have a long service life without being damaged due to mechanical wear. However, their disadvantages are that they are sensitive to environmental factors (such as humidity, static electricity, etc.), and in some cases, mis-triggering may occur.

Circuitry
The circuitry part of the elevator button mainly includes signal transmission lines and control chips. When the triggering mechanism generates a signal, the signal will be transmitted to the control chip through the lines on the printed circuit board (PCB). The control chip processes the signal and converts it into an instruction that the elevator control system can recognize, for example, telling the elevator which floor to go to. The printed circuit board is the carrier of the entire circuit, on which there are various electronic components such as resistors, capacitors, integrated circuits, etc. These components work together to ensure the stable transmission and correct processing of the signal.
Indicator Light
Most elevator buttons are equipped with indicator lights. When the button is pressed, the indicator light will light up, showing the users that their operation has been received. The indicator lights are usually light-emitting diodes (LEDs) because LEDs have the advantages of high brightness, low energy consumption and long service life. The colors of the indicator lights can be various, with common ones being red, green or white. Red is generally used to represent stop, fault and other states; green is used to represent normal operation, running and other states; white is more used for decoration or providing basic visual hints. The position of the indicator light is usually in the center or around the button, and through the transparent or semi-transparent part of the keycap, users can clearly see the state of the indicator light.
