The **W2TS-011-R** is a specific electronic component, typically categorized as a **Surface Mount (SMD) Tactile Switch**. These components are widely used in consumer electronics, industrial controls, and medical devices to provide a physical interface for users to input commands. --- ### 1. General Specifications Below are the typical technical parameters for a switch of this series: | Parameter | Specification | | :--- | :--- | | **Component Type** | Tactile Switch | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Circuit Configuration** | SPST-NO (Single Pole Single Throw, Normally Open) | | **Contact Rating** | 50mA @ 12V DC (Typical) | | **Operating Force** | 160gf to 260gf (varies by sub-model) | | **Travel distance** | 0.25mm ± 0.1mm | | **Lifespan** | 50,000 to 100,000 cycles | --- ### 2. Physical Characteristics The "W2TS" series usually features a compact footprint designed for high-density PCB layouts. * **Actuator:** A small button (often black or metallic) that the user presses. * **Terminals:** Gold or Silver plated leads for soldering onto the board. The "-R" suffix often indicates **Tape and Reel** packaging, suitable for automated pick-and-place assembly. * **Dimensions:** Usually follows standard micro-switch sizing (e.g., 3x2mm or 4x4mm), though specific datasheets should be consulted for exact millimeter dimensions. --- ### 3. Electrical Functionality The switch operates on a simple momentary connection principle: 1. **Rest State:** The circuit is "Open." No current flows between the terminals. 2. **Actuated State:** When the button is pressed, an internal metal dome collapses, creating a bridge between two contacts. The circuit is "Closed." 3. **Release State:** The internal dome springs back to its original shape, breaking the connection. --- ### 4. Common Applications Due to its small size and reliability, the W2TS-011-R is commonly found in: * **Mobile Devices:** Power buttons or volume rockers. * **Wearables:** Smartwatches and fitness trackers. * **Home Automation:** Reset buttons on smart plugs or light switches. * **Peripherals:** Computer mice or keyboard function keys. ---
