The **F2TS-2B-R/BL** is a specific model of an illuminated push-button switch, commonly used in industrial controls, arcade machines, or custom panels. Below is a breakdown of its electronic components and specifications. --- ### 1. Component Breakdown The part number typically follows a structured nomenclature: | Component Code | Description | | :--- | :--- | | **F2TS** | Series identifier (Flat/Flush Square/Round push-button series). | | **2B** | Configuration (Likely 2-pole or a specific mounting size, often 22mm or 30mm). | | **R** | **Red** button cap color. | | **BL** | **Blue** Illumination (LED color). | ### 2. Technical Specifications Most switches in this category share these common electrical characteristics: * **Switching Type:** Momentary (the switch remains active only while pressed). * **Contact Configuration:** Usually 1NO (Normally Open) + 1NC (Normally Closed). * **Voltage Rating:** Typically rated for 12V to 24V DC for the LED, while the switch contacts can often handle up to 250V AC. * **Current Rating:** Standard contacts are rated between 3A to 5A. * **Terminals:** 4 to 5 pins (2 for the switch contacts, 2 for the LED power, and sometimes a common ground). ### 3. Electronic Parts Diagram Internally, the switch consists of three main electronic/mechanical sections: 1. **The Actuator:** The physical "button" that the user presses. 2. **The LED Module:** A light-emitting diode with a built-in resistor (in some versions) to allow direct connection to a power source without burning out. 3. **The Contact Block:** The mechanical bridge that opens or closes the circuit. --- ### 4. Connection Guide (Typical) | Pin Label | Function | Connection | | :--- | :--- | :--- | | **+ / LED+** | LED Anode | Connect to positive power supply (e.g., +12V). | | **- / LED-** | LED Cathode | Connect to Ground/Negative. | | **NO** | Normally Open | Connect to the device you want to turn "ON" when pressed. | | **NC** | Normally Closed | Connect to the device you want to turn "OFF" when pressed. | | **C / COM** | Common | The input power for the device being switched. |
