The **FSE-262-R** is a specific electronic component, typically categorized as a **Surface Mount (SMD) Tactile Switch** or a specific type of **Miniature Slide/Push Switch**, often manufactured by companies like Diptronics or similar electronic hardware suppliers. Below is a detailed breakdown of its electronic characteristics and technical specifications. --- ## 1. Component Overview The FSE-262-R is designed for low-power signal switching in compact electronic devices. It is frequently found in consumer electronics, industrial controls, and medical handheld devices. ### Key Technical Specifications | Feature | Specification (Typical) | | :--- | :--- | | **Switch Type** | Tactile / Push Button (Momentary) | | **Mounting Type** | Surface Mount Technology (SMT) | | **Contact Rating** | 50mA, 12V DC | | **Contact Resistance** | 100mΩ Max | | **Insulation Resistance** | 100MΩ Min at 500V DC | | **Dielectric Strength** | 250V AC for 1 minute | | **Operating Force** | 160gf to 260gf (variation dependent) | | **Operating Life** | 50,000 to 100,000 cycles | --- ## 2. Structural & Material Composition The "R" in the suffix usually denotes **RoHS compliance** or **Tape & Reel packaging**, which is standard for automated pick-and-place assembly lines. * **Contacts:** Usually silver-plated stainless steel or phosphor bronze to ensure high conductivity and corrosion resistance. * **Base/Stem:** High-temperature thermoplastic (e.g., LCP or Nylon) capable of withstanding lead-free reflow soldering temperatures (approx. 260°C). * **Terminals:** Gull-wing or J-lead style for SMT soldering. --- ## 3. Pinout and Circuit Configuration Most components in this series use a **SPST (Single Pole Single Throw)** normally open configuration. ```text [ Terminal 1 ] ----\ ---- [ Terminal 2 ] \ (Switch Gap) [ Terminal 3 ] ----/ ---- [ Terminal 4 ] ``` *Note: In 4-pin tactile switches, terminals 1 & 2 are usually internally connected, as are 3 & 4. Pressing the button bridges the two pairs.* --- ## 4. Typical Applications The FSE-262-R is utilized in circuits where a user interface trigger is required: 1. **Reset Buttons:** For microcontrollers (Arduino, ESP32, etc.). 2. **User Input:** Volume buttons, power switches, or mode selectors in small gadgets. 3. **Keyboards:** Membrane-style keyboards or control panels. ---
