## Overview of the MA11TAG-R The **MA11TAG-R** is a specific electronic component, typically categorized as a **Micro-Miniature Toggle Switch** manufactured by companies like **NKK Switches** or similar high-precision component firms. These switches are designed for PCB (Printed Circuit Board) mounting where space is at a premium. --- ### Key Technical Specifications | Feature | Description | | :--- | :--- | | **Switch Type** | Toggle Switch | | **Circuit Configuration** | SPDT (Single Pole Double Throw) | | **Switch Function** | ON-OFF-ON (or ON-NONE-ON depending on sub-series) | | **Mounting Type** | Right Angle Through-Hole | | **Current Rating** | Typically 0.4VA Max @ 28V AC/DC (Logic Level) | | **Actuator Style** | Bat Lever / Standard Toggle | | **Terminal Material** | Gold-plated (optimized for logic-level switching) | --- ### Internal Electronic Construction The MA11TAG-R is comprised of several critical sub-components that ensure electrical connectivity and mechanical durability: 1. **Actuator (Lever):** The physical handle used to toggle the switch. Usually made of chrome-plated brass or high-temp plastic. 2. **Movable Contact:** A spring-loaded internal mechanism (often a "rocker" or "seesaw" style) that bridges the common terminal to one of the output terminals. 3. **Stationary Terminals:** The physical pins that solder into the PCB. In the "-R" variant, these are bent at a **90-degree angle** for side-mounting. 4. **Housing/Base:** Constructed from heat-resistant resin (like Diallyl Phthalate) to withstand wave soldering temperatures. --- ### Applications Because of its **Right Angle (-R)** orientation and **Logic Level** rating, this part is commonly found in: * **Handheld Devices:** Where the switch needs to be accessible from the side of the enclosure. * **Telecommunications:** For resetting or selecting modes on networking hardware. * **Medical Instrumentation:** High-reliability switching in compact diagnostic tools. * **Testing Equipment:** Used as a configuration or "DIP-style" toggle for user settings. --- ### Typical Pinout Diagram (SPDT) ```text [ Lever ] | +----|----+ | [1] [2] [3] | <-- Terminals (90-degree bend) +-------------+ 1: Fixed Contact A 2: Common (Center) 3: Fixed Contact B ```
