Key Technical Specifications Below are the primary electrical and mechanical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Series** | D4 Series | | **Number of Positions** | 6 Positions | | **Number of Decks** | 1 Deck | | **Number of Poles** | 1 Pole | | **Contact Timing** | Shorting (Make-Before-Break) | | **Voltage Rating (AC)** | 115 VAC | | **Voltage Rating (DC)** | 28 VDC | | **Current Rating** | 1.5A @ 115VAC / 1.5A @ 28VDC | | **Termination Style** | Solder Lug | --- ### 2. Deep Dive into Electronic Features #### A. Contact Timing: Shorting (Make-Before-Break) The "S" in the part number indicates a **Shorting** configuration. - **Mechanism:** As you turn the switch, the wiper connects to the next position before it disconnects from the current one. - **Benefit:** This prevents "electrical noise" or "arcing" during switching, which is critical for audio equipment or sensitive power circuits where a momentary open circuit could cause a spike or system failure. #### B. Materials and Durability - **Contacts:** Typically silver-plated brass or solid silver, ensuring low contact resistance and high conductivity. - **Insulation:** Uses high-grade thermoset plastic or ceramic materials to ensure high dielectric strength and resistance to carbon tracking. - **Housing:** Rugged construction designed to withstand mechanical shock and vibration. #### C. Mounting and Form Factor The unit is designed for **Panel Mounting**. It features a standard threaded bushing and a D-shaped shaft (or flatted shaft) to ensure the knob is oriented correctly and does not slip during high-torque rotation. --- ### 3. Common Applications Due to its robust build, the D4D0106S-R60F is commonly found in: 1. **Industrial Controls:** Selecting modes of operation for heavy machinery. 2. **Test Equipment:** Switching between different measurement ranges or input channels. 3. **Communication Gear:** Frequency or channel selection in radio transceivers. 4. **Audio Engineering:** Input selection in high-fidelity preamplifiers. ---
