The **DPPL07R** refers to a specific series of **DIP Switches** (Dual In-line Package) produced by various electronic component manufacturers (such as **Diptronics**). These are manual electromechanical switches used to customize the behavior of electronic devices. --- ### 1. Technical Specifications The "07" in the part number typically indicates a **7-position** configuration (7 individual switches in one housing), while the "R" often refers to the packaging or actuator style (e.g., Recessed or Reel). | Parameter | Common Specification | | :--- | :--- | | **Number of Positions** | 7 | | **Switch Type** | SPST (Single Pole Single Throw) | | **Contact Rating (Switching)** | 25mA, 24VDC | | **Contact Rating (Non-switching)** | 100mA, 50VDC | | **Operating Force** | 800gf max. | | **Operating Temperature** | -25°C to +70°C | --- ### 2. Physical Design and Construction The device is built to fit standard breadboards and PCB layouts using a **2.54mm (0.1 inch) pitch**. * **Housing:** Usually made of high-temperature UL94V-0 grade thermoplastic (typically blue or red). * **Actuator:** The sliding mechanism. The "R" variant often features a **Recessed Actuator**, which prevents accidental switching and allows for tape-sealing during the soldering process. * **Terminals:** Gold-plated or Tin-plated brass to ensure low contact resistance and prevent oxidation. --- ### 3. Connection Diagram (Internal) Each switch in the 7-position array operates independently. ```text TOP VIEW +-----------+ 1 | [ ] ON | 14 2 | [ ] | 13 3 | [ ] | 12 4 | [ ] | 11 5 | [ ] | 10 6 | [ ] | 9 7 | [ ] | 8 +-----------+ ``` --- ### 4. Common Applications DIP switches like the DPPL07R are used in scenarios where settings do not need to be changed frequently: 1. **Address Setting:** Configuring the unique ID for a device on a bus (e.g., RS-485 or DMX512). 2. **Configuration:** Selecting hardware modes (e.g., setting the baud rate for a communication module). 3. **Security Codes:** Setting the digital key for garage door openers or older wireless remotes. 4. **Hardware Options:** Enabling or disabling specific features on a motherboard or industrial PLC.
