The **TS-2B-R** is a specific model within the **TS Series** of sub-miniature tactile switches, commonly manufactured by companies like **Dailywell** or **C&K**. These components are widely used in consumer electronics for momentary "push-to-make" connections. --- ### 1. Key Technical Specifications The electrical and physical characteristics of the TS-2B-R are standardized to ensure reliability in low-voltage circuits. | Feature | Specification | |:--- |:--- | | **Switch Type** | Tactile (Momentary) | | **Circuit** | SPST (Single Pole Single Throw) | | **Contact Rating** | 50mA @ 12V DC | | **Contact Resistance** | 100 mΩ max (Initial) | | **Insulation Resistance** | 100 MΩ min at 100V DC | | **Dielectric Strength** | 250V AC for 1 minute | | **Operating Force** | 160gf ± 50gf (Standard) | | **Travel** | 0.25mm ± 0.1mm | --- ### 2. Breakdown of the Model Code (TS-2B-R) The nomenclature generally follows this logic: * **TS**: Tactile Switch Series. * **2**: Often refers to the physical size or "style" (commonly 6x6mm footprint). * **B**: Refers to the **Mounting Type**. "B" typically denotes a **Through-Hole** (Plug-in) mounting with specific leg spacing. * **R**: Often indicates **Packaging** (Tape & Reel) or **Actuator Color/Height**. In many tactile series, "R" signifies a Red actuator or a specific height requirement. --- ### 3. Physical Construction The switch is composed of four primary layers: 1. **Actuator (Button):** The plastic part the user presses. In the "R" variant, this is usually a specific height to fit the device casing. 2. **Cover:** A metal shield that holds the components together and provides grounding points. 3. **Contact Dome:** A stainless steel or phosphor bronze disc. When pressed, it collapses to complete the circuit and provides the "click" tactile feedback. 4. **Base:** A high-temperature thermoplastic (usually LCP or Nylon) containing the fixed contact terminals. --- ### 4. Common Applications Due to its small footprint and tactile feedback, the TS-2B-R is found in: * **Consumer Electronics:** Remote controls, toys, and white goods. * **Computer Peripherals:** Reset buttons on routers or motherboards. * **Industrial:** Interface panels and instrumentation. --- ### 5.
