The **W2TG0-1C3-R** is a specific electronic component, typically categorized as a **Micro-Switch** or a **Snap Action Switch**. These parts are commonly used in industrial controls, automotive systems, and consumer appliances due to their reliability and fast switching speed. --- ### 1. General Specifications While specific datasheets can vary slightly by manufacturer (often associated with brands like **Zippy** or similar high-precision switch makers), the part number breakdown generally follows this structure: | Parameter | Specification | | :--- | :--- | | **Component Type** | Snap Action / Micro Switch | | **Circuitry** | SPDT (Single Pole Double Throw) | | **Switch Function** | On-Mom (Momentary) | | **Current Rating** | Typically 0.1A to 3A (Low current/Signal level) | | **Voltage Rating** | 125V AC / 30V DC (Standard) | | **Termination Style** | PCB Terminals (Right Angle or Straight) | --- ### 2. Physical Design & Features The "1C3" and "R" suffixes usually denote the physical configuration of the pins and the lever type: * **Actuator:** Usually a small plunger or a short lever. The "1C3" often refers to the specific force required to actuate the switch (Operating Force). * **Terminal Orientation:** The "R" frequently indicates a **Right Angle** orientation, meaning the pins come out of the side of the switch body to be mounted horizontally on a PCB. * **Gold Contacts:** Many variants in this series use gold-plated contacts to ensure low contact resistance, especially in low-current logic circuits where oxidation could be an issue. --- ### 3. Key Electronic Characteristics #### Contact Configuration (SPDT) The switch features three pins: 1. **COM (Common):** The input line. 2. **NC (Normally Closed):** Connected to COM when the switch is at rest. 3. **NO (Normally Open):** Connected to COM only when the switch is pressed. #### Snap Action Mechanism The "Snap Action" means that the speed at which the contacts move is independent of the speed at which the actuator is moved. This prevents "arcing" and ensures a clean electrical signal. --- ### 4. Common Applications * **Computer Peripherals:** Used in high-end mouse buttons or trackball clicks. * **Safety Interlocks:** Detecting if a door or panel is closed. * **Limit Switches:** In 3D printers or CNC machines to define the "Home" position. * **Automotive:** Detecting seatbelt engagement or door latch status.
