Metal button is a type of switch made from durable materials such as stainless steel or aluminum, used for on-off operations in electronic circuits. When pressed, it opens or closes the circuit. It is commonly used in the following areas:
Industrial machinery
Automation systems
Elevators
Vehicle control panels
Water and dust resistant models are also available, making them a popular choice for outdoor or harsh environments. LED-illuminated versions are also available.
The features to consider when selecting a metal button are as follows:
Momentary metal button is a type of momentary switch that only activates the circuit while being pressed, thanks to a built-in spring mechanism.
Thanks to the spring mechanism, it returns to its original position automatically when released.
Usually “NO (Normally Open)”; it closes the circuit when pressed.
“NC (Normally Closed)” versions are also available.
Doorbell buttons
Machine start/stop controls
Automation systems
Test circuits
When you press an elevator button, it calls the floor, but when you release it, the button returns to its original position — this is a momentary metal button.
Latching metal button is a type of "latching" switch used to open or close a circuit, but it maintains its position when pressed. Unlike momentary buttons, it keeps the circuit continuously on or off after being pressed.
Activates the circuit on the first press,
Deactivates the circuit on the second press (or vice versa).
Mechanically changes position (has a locking mechanism instead of a spring).
Usually has a stainless metal body, durable.
Commonly available with LED illumination.
Electronic power on/off systems
Vehicle control panels
Industrial machines
Computer case power buttons for fixed on/off applications
Momentary button: Works while being pressed; returns when released.
Latching button: Stays in position when pressed; changes only with another press.
