more details about the 16MM Led Metal Button Switch

The 16MM Led Metal Button Switch comes with a wide array of features that make it a top - notch choice for multiple applications.

1. Construction and Durability

Housing Materials: This switch offers flexibility in housing materials. Options typically include brass, stainless steel, and anodized aluminum alloy. Brass provides good electrical conductivity and a classic look. Stainless steel is highly resistant to corrosion, making it suitable for harsh environments such as outdoor installations or in industrial settings where exposure to moisture and chemicals is common. Anodized aluminum alloy is lightweight yet strong, and its anodized finish further enhances its durability and gives it an attractive appearance.

Insulation and Protection: With an insulation resistance of at least 1000 MΩ, it effectively prevents electrical leakage, ensuring safe operation. Many models also come with a high - level protection rating, often reaching IP65 or even IP67. An IP65 rating means the switch is protected against dust ingress and low - pressure water jets from any direction. An IP67 rating offers even more protection, allowing the switch to be temporarily submerged in water up to a certain depth without damage, making it suitable for use in wet or humid conditions.

2. Electrical Specifications

Rated Load: The rated load of the metal button switch can vary, but common ratings include 5A at 110V AC or 2A at 36V DC. This means it can handle a specific amount of electrical current and voltage, making it compatible with a range of electrical systems. For example, in industrial control equipment, it can be used to control motors or other electrical components within its rated capacity.

Contact Resistance: The contact resistance is usually very low, typically ≤ 100 mΩ or even lower in high - quality models. Low contact resistance ensures efficient electrical conduction, minimizing power loss and heat generation during operation. This is crucial for maintaining the performance and longevity of the switch, especially when used in applications where frequent switching occurs.

LED Voltage: The LED in the metal push button switch can operate at different voltage levels. Common options are AC/DC 3 - 6V, AC/DC 12 - 24V, and in some cases, AC 220V. This wide range of LED voltage options allows for easy integration into different electrical systems. For instance, in automotive applications, where the electrical system typically operates at 12V or 24V, the switch can be powered accordingly. In household or industrial settings with a 220V power supply, there are versions available that can directly interface with this voltage for the LED illumination.

3. Operation Modes

Momentary: In the momentary mode, when the button is pressed, the electrical circuit is closed only for as long as the button is held down. As soon as the pressure is released, the switch returns to its original state. This mode is ideal for applications such as starting a short - term process, like triggering a machine to perform a single operation or sounding an alarm for a brief period.

Self - Locking: The self - locking mode, also known as latching, is different. When the button is pressed once, it remains in the "on" position until it is pressed again to turn off. This is useful for applications where a continuous state needs to be maintained, such as keeping a particular electrical device powered on or a control system in a specific operating mode.

4. Customization Options

LED Color: The LED ring around the button is available in a wide spectrum of colors. Standard options include red, green, blue, yellow, white, and sometimes bi - color combinations like red - green or red - blue. The choice of color can be used to convey different meanings. For example, red is often associated with danger or stop, green with go or normal operation, and blue with information or standby status. In industrial control panels, different - colored LEDs can help operators quickly identify the status of various functions.

Button Symbols: Some manufacturers offer the option to customize the button symbols. This allows users to add their own logos, labels, or specific symbols relevant to their application. For example, in a custom - built control panel for a unique piece of machinery, the switch can be labeled with symbols that are meaningful to the operators of that particular equipment
