The **ADE02** is a specific part number typically associated with **DIP Switches** (Dual In-line Package) produced by manufacturers like TE Connectivity (Alcoswitch) or similar electronic component vendors. These are manual electric switches packaged with standard integrated circuit spacing. --- ### 1. Technical Specifications The ADE02 is a **2-position, surface mount (SMD)** or through-hole DIP switch designed for low-current logic switching. | Feature | Specification | | :--- | :--- | | **Number of Positions** | 2 | | **Contact Form** | SPST (Single Pole Single Throw) | | **Actuator Type** | Extended or Flush Slide | | **Current Rating (Switching)** | 25mA to 100mA | | **Voltage Rating** | 5V DC to 24V DC | | **Mounting Type** | Gull-wing (SMD) or Through-hole | | **Operating Temperature** | -30°C to +85°C | --- ### 2. Internal Construction The device consists of several key electronic elements: * **Contacts:** Usually gold-plated to prevent oxidation and ensure reliable electrical connection over long periods of inactivity. * **Housing:** High-temperature plastic (PPS or PBT) capable of withstanding reflow soldering temperatures. * **Sealing:** Often comes with a top tape seal (removable) to allow for automatic washing/cleaning after the soldering process. --- ### 3. Common Applications The ADE02 is used primarily for **configuration** rather than user interaction. Common use cases include: 1. **Address Setting:** Assigning a unique binary ID to a device on a bus (e.g., RS-485 or I2C). 2. **Mode Selection:** Switching between "Debug" and "Normal" operation modes on a PCB. 3. **Hardware Options:** Enabling or disabling specific hardware features (like a pull-up resistor) without changing firmware. --- ### 4. Circuit Diagram Example In a typical digital circuit, the ADE02 is used to pull a microcontroller pin to Ground or VCC. ```arduino // Logic configuration for a 2-position DIP switch VCC (3.3V) | [Resistor 10k] <-- Pull-up | +---- Pin A0 (Microcontroller) | [ADE02 Switch Pos 1] | GND ```
