what is 16mm Rugged Metal Pushbutton with Blue LED Ring

The 16mm Rugged Metal Pushbutton with Blue LED Ring is a meticulously engineered switching solution, specifically optimized for applications in harsh and demanding environments. It masterfully combines robust structural integrity with intuitive status indication, making it a reliable choice for various industrial and commercial uses.

Designed with seamless panel integration in mind, this pushbutton requires a standard 16mm mounting hole, ensuring compatibility with a wide range of existing panel setups. It can accommodate panel thicknesses spanning from 1mm to 13mm, providing flexibility for different installation scenarios. The pushbutton is securely fastened using a hex nut, guaranteeing stability during operation. Additionally, it is sealed with a high-quality rubber gasket, which serves as an effective barrier against environmental elements, protecting the internal components from dust, moisture, and debris.

Constructed from top-tier materials, such as chrome-plated brass or 304 stainless steel, this pushbutton exhibits exceptional durability. These materials endow it with remarkable resistance to scratches, corrosion, and vandalism, enabling it to maintain optimal functionality even in challenging settings, including chemically aggressive environments, wet conditions, or areas with high dust levels. Its rugged build quality is further underscored by its IP65/IP67 ratings. The IP65 rating ensures complete dust tightness and protection against water jets from any direction, while the IP67 rating offers enhanced protection against temporary water immersion. Moreover, it can operate reliably within a wide temperature range of -20°C to +70°C, making it suitable for use in diverse climates and industrial processes.

The 16mm metal switch offers both momentary actuation as standard, providing a quick and responsive operation, and also has an optional latching function for applications that require a maintained state. With an operating force of 1.5-2.5N and a 2mm stroke, it delivers a distinct and satisfying tactile feedback, ensuring positive actuation even when the user is wearing gloves. This feature is crucial in industrial settings where operators often need to wear protective gear. In terms of electrical performance, the pushbutton has an impressive 3A/250VAC rating, ensuring it can handle significant electrical loads. It also boasts a low contact resistance of <50mΩ, minimizing power loss and ensuring efficient operation, and an insulation resistance of >1000MΩ, enhancing safety and reliability. Its mechanical lifespan exceeds 500,000 cycles, demonstrating its long-term durability and reducing the need for frequent replacements.

A standout feature of this pushbutton is the 180° visible blue LED ring. Illuminating with a clear and bright blue light, it provides instant visual feedback, making it easy to identify the status of the switch, especially in low-light conditions or high-traffic environments. The LED is powered by a versatile 3-24VDC supply, offering flexibility in different electrical systems. It comes with a built-in resistor, simplifying the wiring process, although an external 470Ω resistor is required for 12V/24V systems to ensure proper operation. The LED and switch circuits are independent, allowing for flexible wiring configurations. For example, users can choose to have the LED always on for continuous status indication, or only illuminated when the button is pressed, depending on the specific requirements of their application.

This metal pushbutton is ideally suited for a wide array of applications, including industrial control panels, where precise and reliable switching is essential; transportation systems, such as trains, buses, and control panels in vehicles; security terminals, where durability and visibility are key; and outdoor equipment, which needs to withstand harsh weather conditions. By combining operational reliability with intuitive status signaling, it provides a critical advantage in environments where quick and accurate identification of the switch status is paramount.
