The **2TS-5A-R** is a specific model of a **Tactile Switch** (also known as a momentary push-button switch). These components are widely used in consumer electronics, industrial controls, and PCB designs where a physical "click" feedback is required. --- ### 1. Technical Specifications The part number typically follows a standard nomenclature for electronic switches. Below are the common technical parameters for this component: | Feature | Specification (Typical) | | :--- | :--- | | **Switch Type** | Tactile (Momentary) | | **Mounting Type** | Through-Hole (THT) or Surface Mount (SMD) | | **Circuit** | SPST-NO (Single Pole Single Throw, Normally Open) | | **Current Rating** | 50mA | | **Voltage Rating** | 12V DC | | **Actuation Force** | 160gf to 250gf (Grams-force) | | **Operating Life** | 100,000 to 1,000,000 cycles | | **Contact Resistance** | < 100 mΩ | --- ### 2. Physical Characteristics The "2TS" series generally refers to the physical footprint and the "R" suffix often denotes packaging (like **Tape & Reel**) or a specific orientation (like **Right Angle**). * **Actuator:** Usually a small round button made of plastic. * **Terminals:** Typically has 4 pins. Even though it is a SPST switch, 4 pins are used for mechanical stability on the PCB. * **Tactile Feedback:** Provides a distinct "snap" or "click" sensation when pressed, letting the user know the connection has been made. --- ### 3. Pin Configuration (SPST) Internally, the switch connects two sets of pins when pressed. ```text (1)-------(2) <- Internal Connection | | [ ] OFF [ ] <- Button Open | | (3)-------(4) <- Internal Connection ``` * **Pins 1 and 2** are internally shorted. * **Pins 3 and 4** are internally shorted. * When the button is **pressed**, all four pins (1, 2, 3, and 4) become electrically connected. --- ### 4. Common Applications * **Consumer Electronics:** Power buttons on monitors, volume buttons on remote controls. * **Computing:** Reset buttons on motherboards or peripheral input devices. * **Industrial:** Interface panels for machinery. * **Prototyping:** Frequently used with Arduino or Raspberry Pi breadboard projects. ---
