The **FTS-2F-R/BL** is a specialized electronic component, typically categorized as a **Foot Switch** or **Pedal Switch**. These are commonly used in industrial machinery, medical equipment, and musical electronics to provide hands-free control. --- ### 1. General Specifications The model name generally breaks down into functional attributes. While specifications can vary slightly by manufacturer (commonly produced by brands like *Focus* or *Fujisoku*), the standard configuration is as follows: | Feature | Specification | | :--- | :--- | | **Type** | Momentary Foot Switch | | **Circuitry** | SPDT (Single Pole Double Throw) | | **Contact Rating** | Usually 10A @ 250VAC | | **Housing Material** | Zinc Die-cast or Heavy-duty Plastic | | **Color Code** | R (Red) / BL (Blue or Black) | | **Action** | Push-to-make (Non-latching) | --- ### 2. Internal Electronic Parts The FTS-2F series consists of several key electromechanical components: * **Microswitch Assembly:** The core electronic part. It is a snap-action switch that triggers when the pedal is depressed. * **Return Spring:** A mechanical component that ensures the switch returns to the "Open" position once foot pressure is removed. * **Wiring Terminals:** Usually features three terminals: 1. **COM (Common):** The input line. 2. **NO (Normally Open):** The circuit is completed only when pressed. 3. **NC (Normally Closed):** The circuit is broken when pressed. * **Strain Relief:** A rubber or plastic grommet at the cable entry point to prevent the internal wires from being pulled out during heavy use. --- ### 3. Wiring Logic To integrate this part into a circuit, you would typically follow this logic: ```c // Logic for a Microcontroller integration (e.g., Arduino) void setup() { pinMode(FOOT_SWITCH_PIN, INPUT_PULLUP); // Connect COM to GND, NO to Pin } void loop() { if (digitalRead(FOOT_SWITCH_PIN) == LOW) { // Action triggered when pedal is pressed activateMachine(); } } ``` --- ### 4. Application Areas * **Industrial:** Controlling sewing machines, press drills, or heavy soldering stations. * **Medical:** Actuating dental chairs or imaging equipment. * **Audio/Visual:** Used as a "Sustain" pedal or a "Talkback" switch in broadcast studios.
