The **DLB22-R11XY** is typically identified as a high-quality **industrial pushbutton switch**, commonly manufactured by brands like **NKK Switches**. These components are designed for panel mounting in control systems, medical equipment, and broadcast consoles. --- ## 1. Technical Specifications The part number "DLB22-R11XY" follows a specific nomenclature that defines its electronic and physical characteristics: | Specification | Details | | :--- | :--- | | **Switch Type** | Pushbutton (Snap-Action) | | **Circuit Configuration** | DPDT (Double Pole Double Throw) | | **Switching Function** | ON-ON (Maintained/Alternate action) | | **Current Rating** | 5A @ 125V AC / 3A @ 250V AC | | **Contact Material** | Silver Clad (standard for power circuits) | | **Illumination** | Non-Illuminated (Standard for this specific suffix) | | **Terminal Type** | Solder Lug | --- ## 2. Internal Electronic Components ### A. Contact Mechanism The "22" in the model name indicates a **DPDT** configuration. Internally, it contains two separate sets of contacts that switch simultaneously. This allows the switch to control two independent circuits at once (e.g., turning on a motor while simultaneously lighting a status indicator). ### B. Snap-Action Spring The DLB series utilizes a rugged snap-action mechanism. This provides: * **Tactile Feedback:** A physical "click" felt by the operator. * **Arc Reduction:** Rapid contact transfer minimizes electrical arcing, extending the lifespan of the silver contacts. ### C. Terminals The terminals are usually silver-plated brass, designed for **Solder Lug** connections. This ensures a low-resistance electrical path and high vibration resistance compared to screw terminals. --- ## 3. Physical & Environmental Attributes * **Mounting:** Designed for a 12.5mm (approx. 0.5 inch) circular panel cutout. * **Mechanical Life:** Typically rated for over 30,000 cycles. * **Dielectric Strength:** Usually 1,000V AC minimum between contacts, providing safety against high-voltage surges. --- ## 4. Typical Applications Due to the DPDT nature and the 5A rating, this part is commonly used in: 1. **Industrial Control Panels:** As a master toggle or mode selector. 2. **Audio/Visual Gear:** For routing dual signals. 3. **Test Equipment:** Where reliable signal switching is required over thousands of operations.
