The **W2CE-11Y-R/N** is a specific model of an **Illuminated Push Button Switch**, typically used in industrial control panels, automation systems, and machinery interfaces. It is characterized by its compact design, color coding, and electrical ratings. --- ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Model Number** | W2CE-11Y-R/N | | **Switch Type** | Momentary Push Button | | **Contact Configuration** | 1NO + 1NC (1 Normally Open + 1 Normally Closed) | | **Illumination** | LED Integrated | | **Color** | Red (R) or Yellow (Y) depending on specific suffix variants | | **Voltage Rating** | Typically 12V to 24V DC/AC (Model specific) | | **Mounting Diameter** | 22mm (Standard industrial size) | --- ### 2. Breakdown of the Part Number Components The alphanumeric code provides specific details about the component's architecture: * **W2 Series:** Refers to the physical series/body style, often signifying a 22mm mounting diameter which is a global standard for industrial panels. * **CE:** Usually indicates the contact block type or a specific environmental certification (such as CE marking for European safety standards). * **11:** Represents the contact arrangement. "11" typically denotes **1 NO** and **1 NC** contact. * **Y:** Often indicates the shape or mounting style (e.g., Round or Flush). * **R/N:** * **R:** Generally stands for **Red**, indicating the color of the actuator or the LED. * **N:** Can denote a specific terminal type (like Screw Terminals) or a Neon/LED lamp type. --- ### 3. Key Electronic Components Inside this unit, there are three primary electronic/mechanical parts: 1. **The Actuator:** The physical button that the operator presses. In the "R" variant, this is a translucent red cap designed to disperse light from the internal LED. 2. **The LED Module:** An integrated Light Emitting Diode. Unlike old incandescent bulbs, these are vibration-resistant and have a long lifespan (approx. 50,000+ hours). 3. **The Contact Block:** This is the electrical switch mechanism. * The **NO (Normally Open)** circuit closes when the button is pressed. * The **NC (Normally Closed)** circuit opens when the button is pressed. --- ### 4. Typical Application Circuit The switch is often wired in a "Control Circuit" where the LED is powered separately from the load to indicate status. ```cpp // Logic representation of the NO contact if (Button_Pressed == TRUE) { Motor_Relay = ON; Status_LED = ON; } else { Motor_Relay = OFF; Status_LED = OFF; } ``` ---
