It belongs to the **D4 Series** manufactured by **Electroswitch**, known for their rugged construction and high reliability. --- ### ## Technical Specifications Below are the primary electrical and mechanical characteristics of the D4D0106S-R60C: | Feature | Specification | | :--- | :--- | | **Circuitry** | 1 Pole (1P) | | **Positions** | 2 to 6 positions (Adjustable stop) | | **Index Angle** | 30° indexing | | **Contact Timing** | Shorting (Make-Before-Break) | | **Current Rating** | 1.5 Amps @ 115 VAC; 0.25 Amps @ 28 VDC | | **Contact Material** | Silver Alloy | | **Termination Style** | Solder Lug | | **Mounting Type** | Panel Mount | --- ### ### Key Electronic Components & Design #### 1. Contact Mechanism (Shorting) The "S" in the part number suffix typically indicates **Shorting** contacts (Make-Before-Break). This means that during the transition between positions, the switch momentarily connects the new contact before disconnecting from the old one. This is critical in audio or power applications to prevent "pops" or open-circuit spikes. #### 2. Wiping Action The internal contacts utilize a "wiping" action. As the switch rotates, the contacts rub against each other, which helps to: * Remove surface oxidation. * Maintain low contact resistance over the life of the component. * Ensure signal integrity in low-voltage circuits. #### 3. Rugged Materials * **Insulation:** Usually constructed with Glass Epoxy or Diallyl Phthalate, providing high dielectric strength and resistance to heat. * **Silver Plating:** The silver-plated brass or solid silver alloy ensures excellent conductivity and minimizes signal loss. --- ### ### Common Applications This specific rotary switch is designed for precision switching in demanding environments: * **Test Equipment:** For range selection in multimeters or oscilloscopes. * **Communication Radios:** For frequency or channel selection. * **Industrial Controls:** Heavy-duty mode selection for machinery. * **Medical Instrumentation:** Where high reliability is non-negotiable. --- ### ### Schematic Representation (Generic 1P6T) ```text (Common) | /-----*-----\ | | | | | | 1 2 3 4 5 6 (Output Positions) ```
