### Overview of W2TS-213-R The **W2TS-213-R** is a specific model of a **Miniature Toggle Switch**. It is commonly utilized in industrial control panels, medical equipment, and telecommunications for low-power signal switching. --- ### Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Circuit Configuration** | SPDT (Single Pole Double Throw) | | **Switching Function** | ON - ON (2-Position) | | **Contact Rating** | 3A @ 125VAC / 1A @ 250VAC | | **Mounting Type** | Panel Mount / Through-Hole | | **Terminal Type** | Solder Lug / PC Pin | | **Operating Temperature** | -25°C to +85°C | --- ### Detailed Electronic Components #### 1. Internal Contacts The internal switching mechanism typically uses **Silver-plated copper** or **Gold over Silver** contacts. * **Silver:** High conductivity for power switching. * **Gold:** Prevents oxidation, making it ideal for low-energy (logic level) circuits. #### 2. Actuator (Toggle) The "2" in the part number often refers to the actuator length or style. It is usually a chrome-plated brass bat-style handle that provides mechanical leverage to move the internal contact bridge. #### 3. Housing and Base * **Case:** Often made of Diallyl Phthalate (DAP), a high-strength, flame-retardant plastic that maintains high insulation resistance even under heat. * **Bushings:** Standard threaded bushings (typically 1/4-40) allow for secure panel mounting using a locking nut and washer. --- ### Terminal Configuration (SPDT) As an SPDT switch, the W2TS-213-R features **three terminals**: 1. **Common (Center):** The input or shared point. 2. **Position 1 (Top):** Connected to Common when the toggle is in the "Down" position. 3. **Position 2 (Bottom):** Connected to Common when the toggle is in the "Up" position. --- ### Typical Applications * **Audio Equipment:** Signal routing and bypass switching. * **Test Instruments:** Power on/off or mode selection. * **DIY Electronics:** Logic high/low state selection for microcontrollers.
