The **17TG-B6-R** is a specific electronic component typically identified as a **Miniature Toggle Switch** manufactured by **Copal Electronics** (now part of Nidec Components). These switches are widely used in industrial control panels, medical equipment, and telecommunications due to their reliability and compact size. --- ### 1. Key Technical Specifications Below are the fundamental electrical and mechanical characteristics of the 17TG-B6-R: | Feature | Specification | | :--- | :--- | | **Switch Type** | Toggle Switch | | **Contact Form** | SPDT (Single Pole Double Throw) | | **Switching Function** | ON - ON | | **Current Rating** | ~6A @ 125VAC / 3A @ 250VAC | | **Termination Style** | PC Pin (Through-hole) | | **Actuator Style** | Standard Bat Lever | | **Mounting Type** | PCB Mount / Panel Mount with Nut | --- ### 2. Breakdown of Parts and Materials The switch is constructed using high-quality materials to ensure longevity and electrical conductivity: * **Actuator (Lever):** Typically made of chrome-plated brass for durability and corrosion resistance. * **Housing/Body:** Usually made of Diallyl Phthalate (DAP), a high-strength thermoset plastic with excellent insulation properties. * **Contacts:** Silver-plated or gold-plated copper alloy to minimize contact resistance. * **Terminals:** Sealed to prevent flux or contaminants from entering the switch during the soldering process. --- ### 3. Pin Configuration and Circuitry As an **SPDT** switch, it has three terminals. The operation follows this logic: 1. **Terminal 1:** Output A 2. **Terminal 2:** Common (COM) 3. **Terminal 3:** Output B In the "ON-ON" configuration, the Common pin is always connected to either Terminal 1 or Terminal 3, depending on the position of the toggle lever. There is no "Center OFF" position for this specific model. --- ### 4. Application Use Cases * **Audio Equipment:** Routing signals between two different outputs. * **Power Supplies:** Switching between high/low voltage modes or input sources. * **Industrial Controls:** Manual override switches for automated systems. * **Test Instruments:** Selecting between different measurement ranges or functions.
