The **MAH11FBA-R** is a specialized electronic component, typically categorized as a **Micro-Switch** or **Snap Action Switch**. These switches are designed to trigger a rapid change in contact state with a very small physical movement. --- ### 1. Key Technical Specifications Below are the general technical parameters typical for the MAH series (Note: always verify with the manufacturer's specific datasheet for the exact "FBA-R" revision): | Parameter | Specification (Typical) | | :--- | :--- | | **Switch Type** | Snap Action / Micro Switch | | **Actuator Type** | Lever (often a simulated roller or straight lever) | | **Current Rating** | 0.1A to 5A (depending on load type) | | **Voltage Rating** | 125V AC / 250V AC | | **Circuitry** | SPDT (Single Pole Double Throw) | | **Termination Style** | Solder Lug or PCB Terminals | | **Operating Force** | Low to Medium (approx. 50g - 150g) | --- ### 2. Functional Components The MAH11FBA-R consists of several internal and external electronic parts: 1. **Plunger/Actuator:** The physical interface that receives the external force. The "BA-R" suffix often indicates a specific lever arm shape or orientation. 2. **Snap-Action Mechanism:** A spring-loaded internal leaf that ensures the contacts move at a constant speed, regardless of how fast the actuator is pressed. This prevents "arcing" and increases component life. 3. **Silver/Gold Contacts:** High-conductivity metal pads that open or close the circuit. 4. **Housing:** A heat-resistant thermoplastic (often PBT or Phenolic) that protects the internal mechanisms. --- ### 3. Applications This specific part is commonly found in: * **Industrial Controls:** Limit switches for moving machinery. * **Consumer Electronics:** Door interlocks for microwaves or printers. * **Automotive:** Gear shifters or door latch detection. * **Medical Equipment:** Sensitive pressure or position detection. --- ### 4.
