The **KTS-13-R** is an electronic component primarily classified as a **Side Actuated Tactile Switch**. These switches are widely used in consumer electronics, industrial controls, and portable devices where a physical user interface is required to provide tactile feedback (a "click") when pressed. --- ### 1. General Specifications The KTS-13-R is designed for Surface Mount Technology (SMT) applications. Below are the typical technical parameters for this part: | Parameter | Specification | | :--- | :--- | | **Type** | Tactile Switch (Momentary) | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Orientation** | Right Angle / Side Actuated | | **Contact Arrangement** | SPST (Single Pole Single Throw) | | **Current Rating** | 50mA | | **Voltage Rating** | 12V DC | | **Operating Force** | Typically 160gf to 250gf | | **Travel distance** | 0.25mm ± 0.1mm | --- ### 2. Physical Construction The "R" in the suffix usually denotes "Right Angle," meaning the actuator is pressed horizontally relative to the PCB surface. 1. **Actuator:** The button that the user presses. In the KTS-13-R, this is often a small plastic stem located on the side of the housing. 2. **Contact Dome:** A metal disc (usually stainless steel) that provides the "snap" feeling and completes the electrical circuit when compressed. 3. **Housing:** A heat-resistant plastic (LCP or Nylon) capable of withstanding lead-free reflow soldering temperatures. 4. **Terminals:** Silver-plated or gold-plated copper alloy pins for electrical connectivity. --- ### 3. Pinout and Circuitry As an **SPST-NO (Normally Open)** switch, the KTS-13-R has a very simple internal logic: * **State A (Idle):** The circuit is open; no current flows. * **State B (Pressed):** The dome collapses, connecting the input terminal to the output terminal; the circuit is closed. ```text [ Terminal 1 ] ----/ ---- [ Terminal 2 ] (Switch) ``` --- ### 4. Common Applications Due to its low profile and side-actuation, the KTS-13-R is found in: * **Mobile Devices:** Volume rockers or power buttons on smartphones. * **Wearables:** Side buttons on smartwatches or fitness trackers. * **Computing:** Reset buttons on motherboards or peripherals. * **Audio Equipment:** Function selection on MP3 players or Bluetooth speakers. ---
