How to Choose a Metal Button?

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:

• Button Type: Latching or Momentary
• Head Type: Raised or Flat
• Light: Illuminated or Non-illuminated
• Light Symbol: With Power Icon or Without

Momentary Metal Button

Momentary metal button is a type of momentary switch that only activates the circuit while being pressed, thanks to a built-in spring mechanism.

Features:

• 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.

Where is it used?

• Doorbell buttons

• Machine start/stop controls

• Automation systems

• Test circuits

Example:

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

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.

Features:

• 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.

Where is it used?

• Electronic power on/off systems

• Vehicle control panels

• Industrial machines

• Computer case power buttons for fixed on/off applications

What's the difference?

• Momentary button: Works while being pressed; returns when released.

• Latching button: Stays in position when pressed; changes only with another press.
