Based on the part number **W2AC-AACB-R/Q**, this component belongs to the **W2 Series** of miniature rocker switches, typically manufactured by companies like **CIT Relay & Switch** or similar industrial component suppliers. Below is the technical breakdown of its electronic and physical specifications. --- ### 1. Part Number Breakdown | Segment | Code | Description | | :--- | :--- | :--- | | **Series** | W2 | Miniature Rocker Switch (Power Rated) | | **Circuit** | AC | **DPDT** (Double Pole Double Throw) | | **Function** | A | **ON-ON** (Maintained positions) | | **Actuator** | A | Standard Rocker Actuator | | **Housing** | C | Standard Black Housing | | **Terminal** | B | **Solder Lug** (standard connection) | | **Rating** | R/Q | Contact Material (Silver/Gold over Silver) | --- ### 2. Technical Specifications These switches are designed for high-density power switching in a compact form factor. #### Electrical Ratings * **Contact Rating:** Typically 6A @ 125VAC or 3A @ 250VAC. * **Contact Resistance:** $< 50 \text{ m}\Omega$ (initial). * **Insulation Resistance:** $> 1000 \text{ M}\Omega$ at 500VDC. * **Dielectric Strength:** $1500 \text{ V}_{\text{RMS}}$ minimum at sea level. #### Physical Attributes * **Mounting Type:** Panel Mount (Snap-in). * **Operating Temperature:** $-40^\circ\text{C}$ to $+85^\circ\text{C}$. * **Mechanical Life:** 30,000 to 50,000 cycles. * **Actuator Material:** Nylon 6/6, UL 94V-2 flame retardant. --- ### 3. Circuit Configuration (DPDT) The **AC** designation indicates a Double Pole Double Throw configuration. This allows the switch to control two separate circuits simultaneously, toggling between two output paths. ```text Terminal 1 ---| |--- Terminal 4 Terminal 2 (Common A) Terminal 5 (Common B) Terminal 3 ---| |--- Terminal 6 ``` --- ### 4. Contact Material (R/Q) The **R/Q** suffix usually denotes a dual-rated contact system: 1. **Silver Plating:** Best for high-current AC power applications. 2. **Gold over Silver:** Provides a reliable connection for low-level (logic) signals while still maintaining the capacity for power switching if the gold layer wears off. ---
