Based on the part number **10TK-536-R**, this component is a **Tactile Switch** (specifically a miniature push-button switch) commonly used in consumer electronics, PCB assemblies, and interface panels. Below is a detailed breakdown of its electronic specifications and characteristics. --- ### ## Technical Specifications The "10TK" series typically refers to high-quality tactile switches designed for surface mount or through-hole applications. | Feature | Specification | | :--- | :--- | | **Component Type** | Tactile Switch (Momentary) | | **Mounting Style** | Surface Mount (SMT/SMD) or Through-Hole (check specific footprint) | | **Circuitry** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Current Rating** | Typically 50mA | | **Voltage Rating** | 12V DC | | **Contact Resistance** | < 100 mΩ | | **Operating Force** | 160gf to 260gf (depending on specific sub-model) | | **Travel Distance** | ~0.25mm | | **Lifespan** | 100,000 to 500,000 cycles | --- ### ## Construction & Materials The part number suffix and prefix indicate specific material properties: * **Actuator:** Usually made of high-temperature plastic (LCP or Nylon) to withstand soldering. * **Base:** Heat-resistant resin. * **Contacts:** Silver-plated (standard) or Gold-plated (for low-current precision). * **Terminals:** Copper alloy with tin plating. * **"R" Suffix:** Often denotes **RoHS Compliance** (Lead-free) or **Tape & Reel** packaging for automated pick-and-place machines. --- ### ## Common Applications These switches are found in devices where user feedback (a "click") is required: 1. **Consumer Electronics:** Remote controls, microwave panels, and cameras. 2. **Computing:** Reset buttons on motherboards or peripheral buttons. 3. **Industrial:** Interface buttons on PLC modules or handheld testers. 4. **Automotive:** Steering wheel controls and dashboard adjustments. --- ### ## Implementation Example In a digital circuit, this switch is typically used with a pull-up resistor to trigger an interrupt or logic change on a Microcontroller (MCU). ```cpp // Basic Arduino Logic for a Tactile Switch const int buttonPin = 2; int buttonState = 0; void setup() { pinMode(buttonPin, INPUT_PULLUP); // Uses internal resistor } void loop() { buttonState = digitalRead(buttonPin); if (buttonState == LOW) { // Switch is pressed } } ```
