### G3T13AB-R Electronic Component Overview The **G3T13AB-R** is a specific model of a subminiature process-sealed toggle switch manufactured by **NKK Switches**. It is widely used in electronic circuits where space is limited and protection against soldering contaminants is required. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Circuit Type** | SPDT (Single Pole Double Throw) | | **Switch Function** | ON-OFF-ON | | **Current Rating** | 0.4VA Max @ 28V AC/DC Max (Logic Level) | | **Termination Style** | Right Angle PC Terminals | | **Actuator Style** | Standard Lever | | **Mounting Type** | Through-hole, Surface Mount compatible (G3T series) | | **Operating Temp** | -30°C to +85°C | --- ### 2. Physical Design and Construction - **Subminiature Size:** Designed for high-density PCB mounting. - **Process Sealed:** The switch is constructed to withstand automated soldering and washing processes. It features an internal O-ring and a sealed base to prevent flux or cleaning solvents from entering the contact mechanism. - **Twin Crossbar Contact:** Uses a gold-plated "Twin Crossbar" mechanism which ensures high reliability, especially in low-voltage/logic-level applications where oxidation could otherwise cause failures. --- ### 3. Part Number Breakdown Understanding the nomenclature helps in identifying specific features of the **G3T13AB-R**: 1. **G3T**: The series identifier (Subminiature Process Sealed Antistatic Toggles). 2. **13**: Represents the circuit/pole configuration (SPDT, ON-OFF-ON). 3. **A**: Refers to the actuator (Standard 3.8mm toggle). 4. **B**: Indicates the terminal type/material (Gold contacts, suited for logic levels). 5. **-R**: Specifically denotes **Right Angle** orientation for the terminals. --- ### 4. Common Applications - **Handheld Devices:** Due to its small footprint. - **Telecommunications:** Signal switching in networking gear. - **Medical Equipment:** Where reliability and sealing against fluids are necessary. - **Test & Measurement:** Used in portable diagnostic tools. --- ### 5. Schematic Representation The SPDT (ON-OFF-ON) configuration functions as follows: ```text (OFF) / (1)---(2)---(3) ``` - **Position 1:** Pin 2 connected to Pin 1. - **Center Position:** All pins disconnected (Open). - **Position 2:** Pin 2 connected to Pin 3. ---
