Title: φ16(B) Push Button & Indicator (English Version) Description: The φ16(B) Push Button & Indicator refers to a specific type of electrical component commonly used in the industrial automation and control systems. Here, "φ16" indicates that the button or switch has an outer diameter of 16 millimeters, which is typically measured in accordance with ISO metric standards for push buttons. The letter "B" could refer to various things such as button style (e.g., flat, mushroom, or toggle), button function (momentary or maintained action), or a series code within a particular manufacturer's product line. The "Push Button" part is a mechanical device that, when pressed, sends an electrical signal to the control circuit, usually for switching on/off, activating a process, or providing input to a PLC (Programmable Logic Controller) or other electronic devices. It serves as a user interface for manual operation and control. The "Indicator" mentioned likely refers to an illuminated display element adjacent to or integrated with the push button, which provides visual feedback to indicate the status of the system or the button itself - whether it's in the resting position (off) or activated (on). This might include LED lights, LCD displays, or any other form of illumination that communicates the operational state clearly to the operator. In summary, the φ16(B) Push Button & Indicator is a standard-sized button paired with a status indicator designed for ease of use and clear indication in electrical and automation applications.
