The **2TS-2B-R** is a specific type of **tactile switch** (often referred to as a tact switch) commonly used in consumer electronics, automotive controls, and industrial interfaces. It is designed to provide "tactile feedback" (a physical click) to the user when pressed. Below is a detailed breakdown of its technical specifications and characteristics. --- ### 1. General Specifications The 2TS-2B-R belongs to a family of micro-switch components. While specifications can vary slightly by manufacturer (such as Dailywell or SHOU HAN), the standard parameters are typically as follows: | Feature | Specification | | :--- | :--- | | **Type** | Momentary Push Button (SPST) | | **Contact Rating** | 50mA @ 12V DC | | **Insulation Resistance** | 100MΩ min. at 500V DC | | **Dielectric Strength** | 250V AC for 1 minute | | **Operating Force** | 160gf to 260gf (Grams-force) | | **Travel Distance** | 0.25mm ± 0.1mm | | **Operating Life** | 50,000 to 100,000 cycles | --- ### 2. Physical Construction The "2B" and "R" in the part number usually denote the physical configuration and packaging: * **Form Factor:** It is a through-hole or SMD component (depending on the specific series suffix). * **Actuator:** Usually a short, round plunger. * **Terminals:** Typically has 4 pins. Even though it is a Single Pole Single Throw (SPST) switch, the 4 pins provide mechanical stability on the PCB. Inside, pins 1-2 are connected and pins 3-4 are connected; pressing the button bridges the two pairs. * **"R" Suffix:** Often indicates **RoHS Compliance** (Restriction of Hazardous Substances) or **Tape & Reel** packaging for automated assembly. --- ### 3. Internal Circuit Diagram The internal logic is simple. It remains "Normally Open" (NO) until the actuator is depressed. ```text Terminal 1 ●-------● Terminal 2 | [Switch] | Terminal 3 ●-------● Terminal 4 ``` --- ### 4. Common Applications Due to its small footprint and reliability, the 2TS-2B-R is found in: * **Consumer Electronics:** Reset buttons on routers, volume buttons on MP3 players/radios. * **Home Appliances:** Control panels for microwaves or washing machines. * **Computer Peripherals:** Internal buttons on mice or keyboards. * **Instrumentation:** Mode selection buttons on multimeters or medical devices. --- ### 5. Soldering Recommendations To ensure the longevity of the part, specific thermal profiles should be followed: * **Hand Soldering:** Max 350°C for 3 seconds. * **Reflow Soldering:** Peak temperature of 260°C for a maximum of 10 seconds (if SMD version). ---
