19MM Metal Push Button Switch with Power Logo: A Robust and Visible Control Solution

The 19MM Metal Push Button Switch with a power logo is a high - performance component designed for various applications where durability, clear indication, and reliable operation are crucial.

Physical Design and Construction

With a diameter of 19mm, this round metal push button switch is engineered to fit standard mounting holes, ensuring easy integration into control panels. The switch housing is constructed from durable metals such as brass nickel - plated or stainless steel. Brass nickel - plated versions offer excellent corrosion resistance and an attractive finish, while stainless - steel housings are ideal for environments where extreme durability and resistance to harsh conditions are required. This robust construction allows the switch to withstand mechanical stress, vibration, and impact, making it suitable for industrial, automotive, and marine applications.

Power Logo Illumination

One of the standout features of this rugged metal switch is the power logo illumination. The switch comes with a built - in lighting system that illuminates the power logo. This illumination serves a dual purpose. Firstly, it provides a clear visual indication of the switch's status. In low - light or dark environments, the illuminated power logo makes it easy for operators to locate and identify the switch, enhancing user - friendliness. Secondly, it can act as a power - on indicator. When the connected device is powered, the power logo lights up, giving an immediate visual cue that the system is operational. The lighting is available in different colors, such as blue, red, green, or white, depending on the model, allowing for customization to match the color - coding or aesthetic requirements of the application.

Operational Modes

The 19MM round Metal Push Button Switch offers two main operational modes: momentary (self - resetting) and maintained (self - locking). In momentary mode, when the button is pressed, the switch contacts close, and an electrical connection is made. Once the pressure on the button is released, the switch returns to its original state, and the connection is broken. This mode is suitable for applications where a short - term action is required, such as triggering a single - cycle operation or a momentary signal. In maintained mode, the metal push switch remains in the actuated position after being pressed until it is pressed again to return to the off state. This is useful for functions that need to be kept in a particular state, like power - on/off switches for devices that should remain in operation until deliberately turned off.

Electrical ratings of these metal button switches typically range from 1A to 15A at voltages up to 250VAC, depending on the specific model. They are designed to handle the electrical loads associated with a wide range of applications, from low - power consumer electronics to higher - power industrial equipment. The contact resistance of the switch is kept low, usually less than 50 milliohms initially, ensuring efficient electrical conduction and minimizing power loss. Over time, the switch is engineered to maintain stable contact performance, with a long - lasting mechanical and electrical lifespan. Mechanical lifespans can reach up to 1,000,000 operations, and electrical lifespans can be as high as 50,000 operations, providing reliable performance over an extended period.

Protection and Certification

Many models of the 19MM Metal Switch with a power logo are designed to meet high - level protection standards. They often have an IP (Ingress Protection) rating of IP65 or IP67. An IP65 rating means the switch is protected against dust ingress and water jets from any direction, making it suitable for use in environments where there may be exposure to dust or splashing water, such as industrial plants or outdoor equipment. An IP67 rating offers even more protection, as the switch can be temporarily submerged in water up to 1 meter deep for 30 minutes without damage, which is beneficial for applications in marine or highly humid environments. Additionally, these switches are often compliant with international certifications such as CE, UL, and RoHS. CE compliance indicates that the switch meets the essential health, safety, and environmental protection requirements of the European Union. UL certification from Underwriters Laboratories ensures that the switch has been tested and meets safety standards in North America. RoHS compliance means that the switch is free from hazardous substances, making it environmentally friendly.

Applications

Due to its versatile features, the 19MM round Metal Push Button Switch with a power logo finds applications in various industries. In industrial settings, it is used in control panels for machinery, where its durability and clear indication are essential for operators. In the automotive industry, it can be used for functions such as starting engines, controlling auxiliary equipment like winches or inverters in trucks and off - road vehicles, or as power switches for aftermarket accessories. In the marine industry, its waterproof and corrosion - resistant properties make it suitable for use on boats and ships, controlling navigation lights, pumps, or other electrical systems. It is also used in medical equipment, where reliable operation and clear status indication are crucial for patient safety and equipment functionality, as well as in consumer electronics products that require a durable and visually appealing switch for power or function control.
