The **W2SP-1BB-R2** is a specific electronic component typically classified as a **Slide Switch** or a **Miniature Selection Switch**. These components are widely used in industrial control panels, consumer electronics, and circuit configuration. --- ### 1. Component Overview The W2SP series represents a robust line of slide-action switches designed for PCB (Printed Circuit Board) mounting or panel mounting, depending on the specific housing. | Feature | Specification | | :--- | :--- | | **Component Type** | Slide Switch / Miniature Switch | | **Contact Form** | SPDT (Single Pole Double Throw) | | **Switch Function** | ON-ON (2 positions) | | **Mounting Type** | Through-Hole / PCB Mount | | **Terminal Material** | Silver or Gold Plating (R2 indicates specific plating) | --- ### 2. Technical Characteristics The "R2" suffix in the part number often indicates specific environmental or material ratings. * **Actuator Style:** Usually features a raised slide handle for manual operation. * **Electrical Rating:** Typically rated for low-power signal switching (e.g., 0.4VA at 20V AC/DC) or standard power (e.g., 5A at 125V AC). * **Durability:** Designed for high mechanical life cycles (often exceeding 20,000 - 50,000 operations). * **Sealing:** Many variations in this series include an epoxy seal at the base of the terminals to prevent flux contamination during soldering. --- ### 3. Pin Configuration & Logic As a **Single Pole Double Throw (SPDT)** switch, the W2SP-1BB-R2 typically features 3 pins: 1. **Pin 1:** Input/Output A 2. **Pin 2 (Center):** Common (COM) 3. **Pin 3:** Input/Output B When the slide is moved to Position 1, Pin 2 connects to Pin 1. When moved to Position 2, Pin 2 connects to Pin 3. --- ### 4. Common Applications * **Power Selection:** Switching between battery power and DC jack input. * **Mode Selection:** Toggling between different operating modes in a device (e.g., Manual vs. Auto). * **User Interface:** Simple ON/OFF functionality for handheld devices. --- ### 5.
