The **F2TS-41-R/BL** is a specific model of an illuminated push-button switch, often used in arcade machines (such as Sound Voltex or beatmania IIDX) and industrial control panels. It is manufactured by companies like **Sanwa Denshi** or generic high-quality parts suppliers. ### Technical Specifications | Component | Specification | Details | | :--- | :--- | :--- | | **Type** | Rectangular Push Button | 40mm x 40mm approximate face size | | **Illumination** | LED (Red/Blue/White) | Includes a lamp holder for wedge-base bulbs or LEDs | | **Switch Mechanism** | Microswitch | Usually uses a 0.187" terminal microswitch (Omron or Gersung) | | **Mounting** | Nut-fastened | Secured via a large plastic threaded nut | | **Durability** | High-Cycle | Designed for millions of presses | --- ### Core Electronic Parts The device is modular, meaning it consists of several distinct electronic and mechanical parts that work together: #### 1. The Microswitch The "heart" of the component. It converts the physical press into an electrical signal. * **Terminals:** Usually features three pins (Common, Normally Open, Normally Closed). * **Operating Force:** Measured in grams (e.g., 50g, 100g, 200g). Lower force allows for "feather-touch" triggering. #### 2. The LED/Lamp Assembly This provides the "BL" (Blue) or "R" (Red) illumination mentioned in the model number. * **Voltage:** Typically 5V or 12V DC depending on the internal resistor. * **Socket:** Uses a T10 or "Wedge" style base for easy replacement. * **Polarity:** LEDs are polarity sensitive; the holder is usually marked with `+` and `-`. #### 3. The Housing and Plunger While mechanical, the housing holds the electronics in alignment. * **Lens:** The colored cap that diffuses the light. * **Spring:** Determines the tension of the button return. --- ### Wiring Configuration | Pin Type | Function | Connection Point | | :--- | :--- | :--- | | **Signal (NO)** | Send "Active" signal | Encoder / PC Input | | **Ground (GND)** | Common Ground | Power Supply / Encoder GND | | **LED (+)** | Anode | +5V or +12V Power | | **LED (-)** | Cathode | System Ground | --- ### Key Applications * **Rhythm Games:** Used for high-frequency inputs in music games. * **Industrial Panels:** Large, visible indicators for machine states. * **Vending Machines:** High-durability selection buttons.
