The **TS-0B-R/C** generally refers to a specific series of **Miniature Tactile Switches** (Tact Switches). These are momentary push-button switches commonly used in low-power signal switching applications. Below is a detailed breakdown of its electronic specifications and characteristics. --- ### 1. General Specifications Tactile switches like the TS-0B-R/C are designed for "tactile" feedback, meaning the user feels a "click" when the circuit is completed. | Parameter | Typical Value | | :--- | :--- | | **Contact Type** | SPST (Single Pole Single Throw) | | **Circuitry** | Momentary (Normally Open) | | **Current Rating** | 50mA | | **Voltage Rating** | 12V DC | | **Contact Resistance** | ≤ 100mΩ | | **Insulation Resistance** | ≥ 100MΩ (100V DC) | | **Dielectric Strength** | 250V AC for 1 minute | --- ### 2. Key Electronic Components Internally, the switch consists of four primary parts that dictate its electrical behavior: 1. **The Cover:** Usually metal, protects the internal mechanism. 2. **The Plunger (Actuator):** The part you press. In the "R/C" designation, "R" often refers to a **Round** actuator shape. 3. **The Contact Dome:** A stainless steel or copper alloy disc. This is the heart of the switch. When pressed, it collapses to bridge the gap between the stationary contacts. 4. **The Base:** A high-temperature plastic (LCP or PPA) that holds the stationary terminals. --- ### 3. Pin Configuration and Mounting The TS-0B series usually utilizes **SMD (Surface Mount Device)** or **Through-Hole** pins depending on the specific suffix. * **SMD (Gull-wing):** Ideal for automated PCB assembly. * **Terminals:** Usually 4 pins. Note that pins are often connected in pairs internally (Pin 1 to 2, and Pin 3 to 4). Pressing the switch connects the two pairs. --- ### 4. Application Circuit Example Because these switches handle very low current (50mA), they are almost always used as **Input signals** for Microcontrollers (MCU) rather than power switches for motors or lights. ```cpp // Typical Arduino Wiring // Pin 1: Connected to Ground (GND) // Pin 3: Connected to Digital Pin 2 (with Internal Pull-up Resistor) void setup() { pinMode(2, INPUT_PULLUP); } void loop() { int buttonState = digitalRead(2); if (buttonState == LOW) { // Switch is pressed, contact is made } } ``` --- ### 5. Common Use Cases * **Consumer Electronics:** Remote controls, cameras, and audio equipment. * **Computer Peripherals:** Keyboards and mouse buttons. * **Industrial:** Reset buttons on PCBs and interface navigation. ---
