The **TSKC-3SLP-R** is a specific model of a **Tactile Switch** (often referred to as a micro-switch or push-button switch). These components are widely used in consumer electronics for user interface controls due to their small footprint and tactile feedback. --- ## 1. Component Overview The TSKC-3SLP-R belongs to the category of **Surface Mount Technology (SMT)** tactile switches. It is designed to be soldered directly onto the surface of a Printed Circuit Board (PCB). ### Key Specifications Table | Feature | Description | | :--- | :--- | | **Switch Type** | Tactile (Momentary Push) | | **Mounting Type** | SMT (Surface Mount) | | **Circuit Configuration** | SPST (Single Pole, Single Throw) | | **Operating Force** | Typically 160gf to 250gf (Standard) | | **Orientation** | Right Angle / Side Actuated | | **Contact Material** | Silver Plated (Standard for low resistance) | | **Termination Style** | Gull-wing or J-bend leads | --- ## 2. Structural and Electronic Design The "SLP" and "R" in the part number usually denote specific mechanical orientations and packaging: * **Side-Actuated (Right Angle):** The "R" often signifies a right-angle orientation. Unlike standard vertical switches, this switch is pressed from the side, making it ideal for buttons located on the edge of a device (e.g., volume buttons on a smartphone). * **Momentary Action:** The circuit is only "Closed" (ON) while the button is actively being pressed. Once released, the internal spring mechanism returns the button to the "Open" (OFF) position. * **Low Profile:** The "LP" designation typically stands for **Low Profile**, meaning the component has a very small height to accommodate slim electronic enclosures. --- ## 3. Typical Application Schematic In a digital circuit, the TSKC-3SLP-R is usually connected to a microcontroller (MCU) pin with a pull-up or pull-down resistor to prevent a "floating" state. ```cpp // Typical Arduino/MCU logic for this switch const int buttonPin = 2; void setup() { pinMode(buttonPin, INPUT_PULLUP); // Internal resistor keeps pin HIGH } void loop() { int buttonState = digitalRead(buttonPin); if (buttonState == LOW) { // Switch is pressed (circuit completed to GND) } } ``` --- ## 4. Common Applications Due to its small size and side-actuation, you will find this part in: * **Wearables:** Smartwatches and fitness trackers. * **Mobile Devices:** Power or volume rockers. * **IoT Modules:** Reset buttons or pairing buttons. * **Portable Medical Gear:** Handheld diagnostic tools.
