The **D4G0106N-R30C** is a high-quality rotary switch manufactured by **Electroswitch**. This specific component is part of their "D4" series, designed for heavy-duty industrial and commercial applications requiring reliable multi-position switching. --- ### 1. Technical Specifications Below are the primary electronic and mechanical parameters for the D4G0106N-R30C: | Parameter | Specification | | :--- | :--- | | **Number of Positions** | 2 to 6 (Adjustable) | | **Number of Decks** | 1 Deck | | **Number of Poles** | 1 Pole | | **Current Rating** | 0.5A @ 125VAC / 0.25A @ 28VDC | | **Contact Timing** | Non-Shorting (Break-before-Make) | | **Indexing Angle** | 30° | | **Mounting Type** | Panel Mount | | **Termination Style** | Solder Lug | --- ### 2. Key Electronic Features #### A. Contact Mechanism (Non-Shorting) The "N" in the part number indicates a **Non-Shorting** (Break-before-make) contact. This means the connection to the previous position is broken before the connection to the next position is established. This is critical in circuits where two power sources or signals must never be connected simultaneously. #### B. Indexing and Rotation * **30° Throw:** This indicates the physical distance between each switch position. * **Adjustable Stops:** The "R30C" suffix often denotes that the switch has an adjustable stop mechanism, allowing the user to limit the rotation to a specific number of positions (e.g., locking it to 4 positions instead of the maximum 6). #### C. Materials and Durability * **Contacts:** Typically silver-plated brass or silver alloy to ensure low contact resistance and long life. * **Insulation:** Usually constructed with glass-reinforced nylon or diallyl phthalate (DAP), providing high dielectric strength and heat resistance. --- ### 3. Application Examples The D4G series is commonly found in equipment where manual signal routing or mode selection is required: * **Audio Equipment:** Selecting input sources or gain stages. * **Test Instruments:** Selecting measurement ranges (Voltage, Amperage, Resistance). * **Industrial Controls:** Mode selection (Manual/Auto/Off) for heavy machinery. * **Avionics:** Cockpit control panels requiring high-reliability tactile feedback. --- ### 4.
