12mm metal push button switch's application

A 12mm metal push button switch is a small-sized control component with a cut-out size diameter of 12mm, made of metal materials and featuring an LED lighting function. It is widely used in various electronic devices and equipment. Here is a detailed introduction:

Appearance and Material

1.Material: Usually made of aluminum alloy or stainless steel. The surface is treated by anodizing, which not only has a delicate touch and a strong metallic texture but also is corrosion-resistant and wear-resistant.

2. Appearance Design: It has a variety of styles, such as a circular head, a ring-shaped head, etc. Some button switches also have a spherical light-emitting design, which can emit a soft light when powered on, increasing the visual effect.

Function

1. Illuminated Function: It is equipped with an LED light source inside, and the light color can be selected from red, blue, green, white, and other colors. The light can be used to indicate the working status of the switch, such as power-on or power-off, or to play a decorative role to enhance the technological sense of the device.

2. Switching Function: There are two main types: self-locking and self-resetting. The self-locking type will lock in the on or off state after being pressed and needs to be pressed again to release it, which is suitable for applications such as power switches. The self-resetting type will automatically return to the original state after being released, which is suitable for momentary control scenarios such as doorbells.

3. Electrical Performance: The rated current of different models varies, generally ranging from 10mA to 5A, and the rated voltage can reach 28VDC or more. Some high-quality products also have characteristics such as high-temperature resistance and anti-sparking, and meet relevant international standards such as UL 61058-1 and IEC 61058-1.

4. Protection Level: Some illuminated metal push button switches have a high protection level, such as IP65 or IP67, which can effectively prevent dust and water jets, and can work stably in outdoor or humid environments.

Application Scenarios

1.Automotive Field: It can be used for the control of car central control panels, audio systems, trunk lights, etc.

2. Computer and Peripherals: As a power switch or reset button for DIY computer cases, or for controlling RGB lighting systems.

3.Audio Equipment: Used for power switches, function control buttons of amplifiers, subwoofers, etc.

4.Industrial Control: Applied to the control panels of industrial equipment, such as the start and stop buttons of machine tools and automated production lines.It usually adopts a standard 12mm aperture design. Just drill a 12mm round hole on the panel, then insert the metal button from the front of the panel, and fix it with a nut or other fixing devices from the back. The wiring is relatively simple, generally only requiring connection to the positive and negative poles to achieve the lighting and switching functions.
