The **G3T23AP-R** is a high-quality, subminiature toggle switch manufactured by **NKK Switches**. It is specifically designed for logic-level applications and is widely used in telecommunications, medical equipment, and instrumentation. --- ### 1. Key Technical Specifications The following table outlines the core electronic and mechanical parameters of the G3T23AP-R: | Feature | Specification | | :--- | :--- | | **Switch Function** | DPDT (Double Pole Double Throw) | | **Switch Operation** | ON-OFF-ON | | **Current/Voltage Rating** | 0.4VA max @ 28V AC/DC max | | **Mounting Type** | Surface Mount (SMD/SMT) - Gull Wing | | **Terminal Type** | PC Pin (Gull Wing) | | **Contact Material** | Phosphor Bronze with Gold Plating | | **Operating Temperature** | -30°C to +85°C | | **Life Cycle (Mechanical)** | 50,000 Cycles | --- ### 2. Functional Characteristics #### **Circuitry: DPDT (Double Pole Double Throw)** This part controls two separate circuits. Because it is a "Double Throw" switch with an **ON-OFF-ON** configuration, it has three positions: 1. **Position 1:** Circuit A is closed. 2. **Center Position:** All circuits are open (OFF). 3. **Position 2:** Circuit B is closed. #### **Logic Level Switching** The G3T series is designed specifically for **low-energy** (logic level) applications. The use of gold-plated contacts ensures high reliability when switching very low voltages and currents where silver contacts might fail due to oxidation. #### **Process Sealed Construction** The switch features a fully sealed body. This allows the component to withstand automated soldering processes and subsequent washing/cleaning without the risk of flux or contaminants entering the internal contact mechanism. --- ### 3. Physical Design and Packaging * **Subminiature Size:** It is one of the smallest toggle switches available, making it ideal for high-density PCB layouts. * **Heat Resistant Resin:** The housing is made of high-temperature-resistant polyphenylene sulfide (PPS), which survives infrared (IR) reflow soldering. * **Tape & Reel (The "-R" Suffix):** The "R" at the end of the part number indicates that the product is supplied on **Tape and Reel** packaging, which is necessary for high-speed automated pick-and-place assembly. --- ### 4. Application Examples * **Handheld Devices:** Due to its tiny footprint. * **Test & Measurement:** Used as a mode selector or reset switch. * **Telecommunications:** Signal routing in networking hardware.
