The **W2TS-313-R** is a specific electronic component, typically categorized as a **Surface Mount (SMD) Tactile Switch**. These switches are designed for low-power signal switching in compact consumer electronics and industrial interfaces. --- ### 1. Key Technical Specifications The following table highlights the general electrical and mechanical characteristics typical for this series: | Property | Specification (Typical) | | :--- | :--- | | **Switch Type** | Tactile / Momentary | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Actuation Force** | 160gf to 250gf (varies by sub-model) | | **Current Rating** | 50mA | | **Voltage Rating** | 12V DC | | **Contact Resistance** | ≤ 100mΩ | | **Operating Life** | 50,000 to 100,000 cycles | --- ### 2. Physical Design Features * **Sealed Construction:** The "W" in the prefix often denotes a "Washable" or "Waterproof" design, meaning the internal contacts are protected against flux during soldering or environmental moisture. * **Compact Footprint:** Designed for high-density PCB layouts where space is limited. * **Tactile Feedback:** Provides a distinct "click" sensation to the user, confirming that the circuit has been closed. * **Lead-Free (R):** The "R" suffix generally indicates compliance with **RoHS** (Restriction of Hazardous Substances) standards and may also imply "Tape and Reel" packaging for automated pick-and-place assembly. --- ### 3. Functional Applications The W2TS-313-R is commonly found in the following types of devices: 1. **Consumer Electronics:** Power buttons on digital cameras, volume controls on MP3 players, or select buttons on smartwatches. 2. **Home Appliances:** Control panels for microwave ovens, washing machines, and thermostats. 3. **Medical Devices:** Handheld diagnostic tools and portable monitors. 4. **Computing:** Reset switches on motherboards or function keys on peripheral devices. --- ### 4. Comparison to Standard Switches Unlike a latching switch (which stays on or off), the W2TS-313-R is **momentary**. The circuit is only completed while the physical button is being depressed. Once released, an internal spring mechanism returns the button to its original position and breaks the connection.
