The **FTS-8A-R/BL** is a specialized electronic component, typically categorized as a **Foot Switch** or **Pedal Switch**, often used in industrial machinery, medical devices, or musical equipment for hands-free operation. Below is an explanation of its technical specifications and electronic characteristics. --- ### Technical Specifications | Feature | Description | | :--- | :--- | | **Model Number** | FTS-8A-R/BL | | **Contact Type** | Momentary (SPDT - Single Pole Double Throw) | | **Current Rating** | Typically 5A to 10A (depending on manufacturer load) | | **Voltage Rating** | 125V AC / 250V AC | | **Color Coding** | **R**: Red / **BL**: Blue (Refers to housing or button color) | | **Material** | Heavy-duty Plastic or Die-cast Metal | ### Internal Electronic Components 1. **Microswitch Mechanism**: Inside the housing is a high-precision microswitch. When the pedal is pressed, a physical lever triggers the switch to change the state from **Normally Open (NO)** to **Closed**. 2. **Contact Terminal Configuration**: * **COM (Common):** The input line. * **NO (Normally Open):** Circuit is completed only when the pedal is pressed. * **NC (Normally Closed):** Circuit is broken when the pedal is pressed. 3. **Spring Return System**: A mechanical compression spring ensures the switch returns to its original electronic state immediately after the user removes their foot. ### Wiring Diagram Logic To use this part in a circuit, follow this logic: ```c // Example logic for a microcontroller integration if (FTS_8A_State == HIGH) { Activate_Machine(); // When pedal is pressed } else { Idle_Mode(); // Default state } ``` ### Application Use Cases * **Industrial Control:** Operating pneumatic valves or motor starters. * **Medical Equipment:** Controlling dental chairs or imaging devices. * **Audio/Visual:** Triggering "Talkback" systems or effects loops. ---
