The **2TS-04-R** is an electronic component primarily identified as a **Tactile Switch** (also known as a momentary push-button switch). These components are widely used in consumer electronics, industrial controls, and PCB assemblies to provide user input through a physical "click" sensation. --- ### 1. Technical Specifications Below are the typical electrical and mechanical specifications for the 2TS-04-R series: | Parameter | Value / Specification | | :--- | :--- | | **Switch Type** | Tactile (Momentary) | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Circuit** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Contact Rating** | 50mA @ 12V DC (Typical) | | **Operating Force** | 160gf to 260gf (Grams-force) | | **Travel** | 0.25mm ± 0.1mm | | **Operating Life** | 100,000 to 500,000 Cycles | | **Contact Resistance** | < 100mΩ | --- ### 2. Physical Characteristics The "04" in the part number often refers to the height or specific size dimension of the switch. * **Actuator:** Usually a small round button or a flat surface flush with the casing. * **Terminals:** Designed for SMT (Surface Mount Technology), allowing for automated "pick and place" assembly on a Printed Circuit Board. * **Material:** High-temperature plastic (LCP or Nylon) to withstand the heat of reflow soldering. * **Feedback:** Provides a distinct tactile "click" (haptic feedback) to the user when the circuit is closed. --- ### 3. Internal Circuitry The device operates as a simple bridge. In its default state, the circuit is open. When the button is pressed, a metal dome inside collapses to connect the internal leads. ```mermaid graph LR A[Pin 1] --- B((Switch)) B --- C[Pin 2] style B fill:#f9f,stroke:#333,stroke-width:2px ``` --- ### 4. Common Applications * **Consumer Electronics:** Remote controls, microwave buttons, and smart home devices. * **Computing:** Mouse buttons, reset switches on motherboards, and keyboard function keys. * **Medical:** Interface buttons for handheld diagnostic tools. * **Industrial:** Interface panels for PLC (Programmable Logic Controllers).
