The part number **10TK-3B0-R** typically refers to a specific series of **Touch Switches (Tactile Switches)**, often manufactured by companies like **Dipty** or other electronic component suppliers specializing in interface hardware. Below is a breakdown of its features, specifications, and typical applications. --- ### 1. Component Overview The 10TK series represents a sub-miniature tactile switch designed for PCB (Printed Circuit Board) mounting. These are momentary "push-to-make" switches that provide physical feedback (a "click") when pressed. | Feature | Description | | :--- | :--- | | **Component Type** | Tactile Switch | | **Mounting Type** | Through-Hole (THT) or SMD (depending on specific suffix) | | **Actuation Force** | Typically 160gf to 260gf | | **Contact Arrangement** | SPST (Single Pole Single Throw) | | **Function** | Momentary (Normally Open) | --- ### 2. Part Number Breakdown (Typical) While manufacturers vary slightly, the nomenclature usually follows this logic: * **10TK**: Series identifier (Size/Design). * **3B0**: Often refers to the **height** of the actuator (plunger) or the specific casing dimensions. * **R**: Generally indicates the **Packaging** (e.g., RoHS Compliant or Tape & Reel) or **Actuation Color/Force**. --- ### 3. Technical Specifications These switches are designed for low-power signal switching rather than high-power loads. | Specification | Value (Standard) | | :--- | :--- | | **Maximum Voltage** | 12V DC | | **Maximum Current** | 50mA | | **Dielectric Strength** | 250V AC for 1 minute | | **Contact Resistance** | ≤ 100mΩ | | **Insulation Resistance** | ≥ 100MΩ (100V DC) | | **Operating Temperature** | -25°C to +70°C | | **Life Cycle** | 100,000 to 500,000 cycles | --- ### 4. Physical Dimensions Tactile switches like the 10TK series usually come in a **6x6mm** or **12x12mm** square footprint. The "3B0" suffix commonly points to a plunger height of approximately **3.0mm to 3.5mm** measured from the base of the switch to the top of the button. --- ### 5. Applications Due to their small size and reliability, these parts are found in: 1. **Consumer Electronics**: Remote controls, microwave panels, and calculators. 2. **Industrial Controls**: Reset buttons on PCBs and interface panels. 3. **Computer Peripherals**: Power buttons and adjustment toggles on monitors. 4. **DIY/Prototyping**: Commonly used on breadboards for Arduino/Raspberry Pi projects. --- ### 6. Installation (Pinout) The switch typically has 4 pins. Internally, pins are connected in pairs. When the button is pressed, it bridges the two pairs, completing the circuit. ```text (1) --- [ Switch ] --- (2) | | (3) --- [ Gap ] --- (4) *Pins 1 & 3 are usually connected internally. *Pins 2 & 4 are usually connected internally. ``` ---
