The **G3T22AH-R** is a high-quality, subminiature process-sealed toggle switch manufactured by **NKK Switches**. It is specifically designed for logic-level applications and surface-mount technology (SMT). --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Circuit Type** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON - ON | | **Contact Rating** | 0.4VA Max @ 28V AC/DC Max (Logic Level) | | **Mounting Type** | Surface Mount (SMT), Right Angle | | **Actuator Style** | Toggle (Gray, Heat Resistant) | | **Mechanical Life** | 50,000 Operations | | **Operating Temp** | -30°C to +85°C | --- ### 2. Major Electronic & Design Components #### A. Contact Mechanism The internal contacts are typically **gold-plated**. This is critical for "logic level" switching because gold does not oxidize, ensuring reliable electrical connectivity even when the voltage and current are too low to break through an oxide layer (arc-less switching). #### B. Process-Sealed Body The "H" in the part number often signifies its sealing properties. The device is constructed to withstand **automated soldering and washing processes**. It features: * An internal O-ring. * Ultrasonically welded housing. * Epoxy-sealed terminals to prevent flux or cleaning agents from entering the contact area. #### C. Terminal Design The terminals are designed for SMT (Surface Mount Technology). The "R" suffix usually denotes the packaging type (**Tape & Reel**), which is essential for automated pick-and-place assembly machines. --- ### 3. Usage Scenarios Because of its small footprint and reliability, the G3T22AH-R is commonly found in: * **Handheld Devices:** Due to its subminiature size. * **Telecommunications:** For signal routing where high current is not required. * **Medical Equipment:** Where reliability and resistance to cleaning fluids are necessary. * **Test & Measurement:** For switching internal logic states or configurations. --- ### 4. Dimensional and Mounting Data The **Right Angle** orientation allows the toggle to be actuated from the side of a PCB, making it ideal for edge-mounting on devices where the user interacts with the side panel.
