The **T-2B6-R** is a specific model of a **Tactile Switch** (also known as a push-button switch) manufactured by companies like **DiPTronics** or similar electronic component vendors. These are commonly used in consumer electronics, automotive controls, and industrial interfaces. --- ### 1. Technical Specifications The T-2B6-R belongs to the category of surface-mount or through-hole tactile switches. Below are the typical technical parameters: | Parameter | Specification (Typical) | | :--- | :--- | | **Switch Type** | Tactile (Momentary) | | **Circuit** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Current Rating** | 50mA | | **Voltage Rating** | 12V DC | | **Contact Resistance** | 100mΩ Max | | **Operating Force** | 160gf (Grams-force) | | **Travel** | 0.25mm | --- ### 2. Key Physical Features * **Form Factor:** It is designed for compact PCB (Printed Circuit Board) integration. * **Actuator:** Usually features a circular button or "stem" that provides a physical "click" sensation (tactile feedback) when pressed. * **Mounting:** The "R" suffix often denotes **RoHS compliance** or specific packaging (like Tape & Reel for automated assembly). * **Durability:** Most T-2B6 series switches are rated for **100,000 to 500,000 cycles**, making them highly reliable for frequent use. --- ### 3. Pinout and Internal Logic The switch acts as a simple bridge. When the button is depressed, it completes the circuit between the input and output pins. ```text Pin 1 ----| |---- Pin 2 | | Pin 3 ----| |---- Pin 4 ``` *Note: In most 4-pin tactile switches, Pin 1 is internally connected to Pin 2, and Pin 3 is connected to Pin 4. Pressing the button connects both pairs.* --- ### 4. Common Applications Due to its small size and reliable feedback, the T-2B6-R is found in: 1. **Computer Peripherals:** Reset buttons, power buttons on monitors. 2. **Home Appliances:** Microwave control panels, washing machine settings. 3. **Industrial:** PLC (Programmable Logic Controller) input modules. 4. **DIY Electronics:** Breadboard prototyping and Arduino projects.
