The **2RS-02-R** typically refers to a **2-position, Right-Angle (RA) Slide Switch** or a **DIP Switch** variant, commonly used in PCB design for configuration and signal routing. Below is a detailed breakdown of its specifications, mechanical structure, and common applications. --- ### 1. General Specifications The "2RS" series is often associated with sub-miniature or micro-switch components. | Feature | Specification (Typical) | | :--- | :--- | | **Switch Type** | Slide Switch / DIP Switch | | **Positions** | 2 positions (ON-ON or ON-OFF) | | **Orientation** | Right-Angle (Horizontal mounting) | | **Terminal Type** | Through-hole (THT) | | **Contact Rating** | 0.4VA @ 20V (AC/DC) or 300mA @ 30V DC | | **Contact Resistance** | < 20 mΩ | | **Insulation Resistance** | > 1000 MΩ | | **Operating Life** | 10,000 to 30,000 cycles | --- ### 2. Mechanical Structure The "R" suffix usually denotes the **Right-Angle** orientation, which is critical for side-access on a device enclosure. * **Actuator:** A small plastic slider used to change the state of the circuit. * **Housing:** Typically made of high-temperature PBT or Liquid Crystal Polymer (LCP) to withstand soldering. * **Terminals:** Brass or copper alloy, often gold-plated to prevent oxidation and ensure reliable low-voltage switching. --- ### 3. Pinout Configuration For a standard 2-position slide switch (SPDT - Single Pole Double Throw): 1. **Pin 1:** Terminal A 2. **Pin 2:** Common (COM) 3. **Pin 3:** Terminal B *When the slider is moved to position 1, Pin 2 connects to Pin 1. When moved to position 2, Pin 2 connects to Pin 3.* --- ### 4. Common Applications * **Power Selection:** Switching between battery power and USB power. * **Mode Configuration:** Setting a device to "Master" or "Slave" mode. * **Logic High/Low:** Setting a digital input pin to either VCC or GND. * **Consumer Electronics:** Power switches for small handheld toys, remote controls, or IoT sensors. --- ### 5. Soldering and Handling * **Manual Soldering:** Use a temperature-controlled iron (approx. 350°C) for no more than 3 seconds to avoid melting the plastic housing. * **Cleaning:** If using an aqueous wash, ensure the switch is a "sealed" model; otherwise, flux ingress can cause contact failure. ---
