The **TS-2B1-R** is a specific type of **Tactile Switch** (commonly known as a push-button switch). These components are widely used in consumer electronics, automotive controls, and industrial interfaces to provide momentary physical feedback to the user. Below is a detailed breakdown of its electronic and physical characteristics. ### 1. Key Technical Specifications While specific manufacturers may have slight variations, the "TS-2B1-R" typically adheres to the following electrical standards: | Feature | Specification | | :--- | :--- | | **Switch Type** | Momentary (Normally Open) | | **Contact Rating** | 50mA @ 12V DC (typical) | | **Contact Resistance** | ≤ 100mΩ | | **Insulation Resistance** | ≥ 100MΩ | | **Dielectric Strength** | 250V AC for 1 minute | | **Operating Force** | 160gf to 250gf (grams-force) | | **Travel distance** | 0.25mm ± 0.1mm | --- ### 2. Physical Construction and Pins The "R" in the part number often denotes specific packaging (like Tape & Reel) or a Right-Angle mounting orientation. * **Actuator:** The button itself, usually made of plastic. The height can vary. * **Contact Dome:** A metal disc (often stainless steel) that collapses when pressed, creating the "click" sound and completing the circuit. * **Terminal Configuration:** Usually features 2 or 4 pins. In a 4-pin configuration, pairs of pins are internally connected to provide mechanical stability on the PCB. * **Mounting Style:** Usually **Through-Hole (THT)** or **Surface Mount (SMD)**. --- ### 3. Basic Circuit Diagram The switch acts as a bridge. When the button is pressed, the internal dome connects Terminal A to Terminal B. ```text [Button Up] [Button Down] (Open Circuit) (Closed Circuit) Pin 1 Pin 2 Pin 1 ----- Pin 2 | | | | | o / o o----o----o / (Gap) (Contact) ``` --- ### 4. Common Applications * **Consumer Electronics:** Power buttons on routers, volume buttons on remote controls. * **Computer Peripherals:** Reset buttons or mode selectors. * **Microcontroller Projects:** Used as "Input" components for Arduino or Raspberry Pi to trigger software events. ---
