The **W2TS-3BC-R** is a specific electronic component, typically categorized under **Pushbutton Switches** or **Panel-Mount Indicators**, often produced by manufacturers like Nidec Copal Electronics or similar industrial suppliers. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. Key Technical Specifications The part number indicates a specific configuration involving the mounting style, circuit logic, and illumination. | Parameter | Specification (Typical) | | :--- | :--- | | **Switch Type** | Pushbutton / Tactile Switch | | **Circuit** | SPDT (Single Pole Double Throw) or DPDT | | **Switching Function** | Momentary (Non-locking) | | **Current Rating** | ~0.1A to 3A @ 125VAC (Depends on specific load) | | **Contact Resistance** | 20mΩ Max | | **Operating Force** | 1.5N to 2.5N | | **Illumination** | Red LED (Indicated by "-R") | | **Mounting Type** | Panel Mount / Through-hole | --- ### 2. Breakdown of the Part Number In the W2TS series, each character represents a specific feature: * **W2TS**: The series identifier (usually representing a waterproof or sub-miniature toggle/pushbutton family). * **3BC**: Refers to the terminal type and the specific mechanical layout (e.g., straight PC terminals or specific bushing sizes). * **R**: Denotes the color **Red**. This usually applies to the LED illumination color or the color of the actuator cap. --- ### 3. Internal Construction * **Contacts:** Usually made of silver-plated copper or gold-plated alloys to ensure high conductivity and prevent oxidation. * **Housing:** High-temperature plastic (e.g., Polyamide or PBT) to withstand soldering heat. * **Sealing:** The "W" in many series suggests a degree of environmental sealing (IP60/IP64) to protect the internal contacts from dust and moisture. --- ### 4. Typical Applications This component is commonly found in industrial and commercial electronics due to its durability: 1. **Control Panels:** Used as a reset or start button. 2. **Instrumentation:** Used in testing equipment where a visual status (Red LED) is required. 3. **Medical Devices:** Used for user interface controls that require tactile feedback. --- ### 5.
