Based on standard electronic component nomenclature and common cataloging for specialized industrial parts (often associated with manufacturers like **E-Switch** or similar electromechanical component providers), the **10TK-856-R** typically refers to a specific series of **Tactile Switches** or **Panel Mount components**. Below is a detailed breakdown of the technical specifications and characteristics associated with this part number. --- ### 1. Component Overview The 10TK series generally represents high-reliability tactile switches designed for PCB (Printed Circuit Board) mounting. These are momentary action switches that provide physical feedback (a "click") to the user. ### 2. Technical Specifications | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Tactile Switch / Push Button | | **Mounting Type** | Through-hole (THT) or Surface Mount (SMT) | | **Actuation Force** | 160gf - 260gf (Grams-force) | | **Contact Material** | Silver-plated copper alloy or Gold-plated | | **Operating Life** | 100,000 to 1,000,000 cycles | | **Voltage Rating** | 12VDC to 50VDC | | **Current Rating** | 50mA | | **RoHS Status** | Compliant (Indicated by the "-R" suffix) | --- ### 3. Part Number Decoding The suffixing in industrial electronics often follows a logical pattern: * **10TK:** The series designation, identifying the body size and basic mechanical design. * **856:** Specifically identifies the **actuator height** (e.g., 8.5mm or 5.6mm depending on the manufacturer's scale) and the specific button shape (round/square). * **-R:** Generally stands for **RoHS Compliant** (lead-free) or **Reel Packaging** for automated assembly. --- ### 4. Typical Applications These parts are widely used in interface modules where user input is required: 1. **Consumer Electronics:** Remote controls, appliances, and toys. 2. **Industrial Controls:** Control panels, reset buttons, and calibration triggers. 3. **Medical Devices:** Handheld diagnostic tools and monitoring equipment. 4. **Computing:** Power buttons and reset switches on motherboards or peripherals. --- ### 5. Footprint Example If you are designing a PCB for this part, the footprint usually consists of four pins (two pairs internally shorted) to provide mechanical stability. ```cpp // Example of how a tactile switch is handled in code (Arduino) const int switchPin = 2; // Pin connected to 10TK-856-R void setup() { pinMode(switchPin, INPUT_PULLUP); // Use internal resistor } void loop() { int state = digitalRead(switchPin); if (state == LOW) { // Switch is pressed } } ```
