The **D4C0106N-R60A** is a specific model of a **Rotary Switch** manufactured by Electroswitch. These components are designed to manually open or close electrical circuits by rotating a knob or shaft. --- ## 1. Technical Specifications The part number describes a specific configuration within the D4 series. Below are the primary technical characteristics: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Electroswitch | | **Series** | D4 Series | | **Number of Positions** | 2 to 6 (Adjustable) | | **Number of Poles** | 1 Pole | | **Number of Decks** | 1 Deck | | **Angle of Throw** | 30° | | **Contact Timing** | Non-Shorting (Break-Before-Make) | | **Current Rating** | 500mA @ 115VAC / 1.5A @ 28VDC | | **Mounting Type** | Panel Mount | --- ## 2. Part Number Breakdown (Nomenclature) The code represents a modular build. Here is how to interpret the segments: 1. **D4**: The Series identifier (High-quality, rugged construction). 2. **C**: Refers to the physical size and construction style (Compact). 3. **01**: Indicates the number of **Poles** (1 pole in this case). 4. **06**: Indicates the number of **Positions** (Up to 6 positions). 5. **N**: Denotes **Non-Shorting** contacts. This means the connection to one position is broken before the connection to the next is made. 6. **R60A**: Specifies the shaft length, finish, and specific rotation limits (30-degree indexing). --- ## 3. Key Internal Components * **Rotor:** The moving part connected to the shaft that makes contact with different terminals. * **Stator (Deck):** The stationary ceramic or diallyl phthalate insulation board that holds the terminals. * **Detent Mechanism:** A spring-loaded ball or "star wheel" that provides the tactile "click" and ensures the switch stays in the selected position. * **Silver Plated Contacts:** Used to ensure low contact resistance and long life. --- ## 4. Typical Applications This switch is often used in industrial or high-end audio equipment where reliability is critical: * **Signal Routing:** Selecting between different audio inputs. * **Mode Selection:** Changing operating modes in test equipment (e.g., Oscilloscopes, Multimeters). * **Industrial Controls:** Manually overriding automated settings or selecting power levels.
