Based on the part number **D-S-10-R**, this typically refers to a **Single-Pole, Single-Throw (SPST) DIP Switch**. These components are widely used on printed circuit boards (PCBs) to manually configure device settings or select operating modes. --- ### Technical Specifications The following table outlines the general characteristics of a standard 10-position DIP switch like the D-S-10-R: | Feature | Specification | | :--- | :--- | | **Switch Type** | DIP (Dual In-line Package) | | **Number of Positions** | 10 individual switches | | **Actuator Style** | Raised (Slide) | | **Circuit Configuration** | SPST (Single Pole Single Throw) | | **Contact Rating** | 25mA @ 24VDC (Switching) / 100mA @ 50VDC (Non-switching) | | **Mounting Type** | Through-hole (THT) | | **Pitch** | 2.54mm (0.1 inch) | --- ### Part Number Breakdown The nomenclature can be broken down to understand the component's physical attributes: * **D**: DIP Switch category. * **S**: Slide type actuator (as opposed to piano or rotary types). * **10**: Indicates **10 positions** (10 independent toggle switches in one housing). * **R**: Generally signifies **Raised** actuators (easier to flip by hand) or **Red** housing color, depending on the specific manufacturer (like Excel Cell Electronic or similar brands). --- ### Component Features 1. **Gold-Plated Contacts**: Most "R" series switches use gold plating on contacts to prevent oxidation and ensure long-term reliability in low-voltage logic circuits. 2. **Heat Resistance**: The base and cover are usually made of high-temperature thermoplastic (PBT or Nylon), allowing the part to withstand wave soldering. 3. **Standard Spacing**: The 2.54mm pitch ensures it fits perfectly into standard breadboards and universal PCB grids. --- ### Common Applications * **Address Settings**: Used in RS-485 or DMX512 networks to set unique device IDs. * **Configuration**: Selecting baud rates or enabling/disabling specific hardware features. * **Prototyping**: Manually simulating digital inputs (High/Low) during the debugging phase of a microcontroller project.
