The **TSKD-2JLE-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, automotive interfaces, and industrial controls to provide a physical "click" sensation and complete an electrical circuit when pressed. --- ### 1. Technical Specifications Below is a breakdown of the typical technical parameters for this part: | Parameter | Specification | |:---|:---| | **Switch Type** | Tactile / Momentary | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Circuit** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Actuation Force** | Typically 160gf to 250gf (varies by sub-series) | | **Dimensions** | Standard compact footprint (e.g., 3.5mm x 2.9mm or similar) | | **Termination Style** | J-Bend or Gull-wing Leads | | **RoHS Status** | Compliant (Lead-free) | --- ### 2. Key Electronic Features * **Momentary Action:** The switch only remains closed (ON) while it is being physically depressed. Once released, the internal spring mechanism returns the contact to the open (OFF) position. * **Tactile Feedback:** The "TS" in the prefix usually denotes "Tactile," meaning the user feels a sharp mechanical resistance (the "click") confirming the switch has been triggered. * **Low Power Rating:** These switches are designed for logic-level signals (low voltage/current). They are not intended to switch power loads directly but rather to send signals to a Microcontroller (MCU). * **SMD Design:** The "JLE" suffix often refers to the lead configuration (J-Leads), which are designed to be soldered directly onto the surface of a PCB, saving space compared to through-hole components. --- ### 3. Common Applications Due to its small form factor and reliability, the TSKD series is frequently found in: 1. **Wearable Electronics:** Smartwatches and fitness trackers. 2. **Portable Devices:** Handheld gaming consoles, remote controls, and digital cameras. 3. **Medical Equipment:** Control panels for portable diagnostic tools. 4. **Automotive:** Steering wheel buttons or dashboard controls. --- ### 4. Circuit Diagram Representation In a standard electronic schematic, the TSKD-2JLE-R is represented as follows: ```text [Push Button] Pin 1 ----/ ---- Pin 2 | (Normally Open) ``` When the button is pressed, the bridge closes, allowing current to flow from Pin 1 to Pin 2, pulling a microcontroller pin to either Ground or VCC (depending on your pull-up/pull-down resistor configuration).
