The **M2AS1-6221-R/CE** is a specialized electronic component, typically categorized as a **Micro-Switch** or **Snap Action Switch**. These components are widely used in industrial controls, automotive systems, and home appliances for position sensing or safety interlocking. --- ### 1. Key Technical Specifications Based on the standard nomenclature for this series of switches, here are the core electronic and physical attributes: | Feature | Specification | Description | | :--- | :--- | :--- | | **Switch Type** | Snap Action / Micro-Switch | High-speed transition regardless of actuation speed. | | **Contact Form** | SPDT (Single Pole Double Throw) | Features one common (COM), one normally open (NO), and one normally closed (NC) terminal. | | **Current Rating** | ~5A to 10A | Rated for standard power loads (varies by specific voltage). | | **Voltage Rating** | 125V / 250V AC | Designed for mains power or high-voltage DC control circuits. | | **Actuator Type** | Lever / Roller Lever | Usually features a mechanical arm to reduce the force required for activation. | | **Termination** | Solder or Quick Connect | Standard metal tabs for wiring or PCB mounting. | --- ### 2. Internal Electronic Structure The internal mechanism of the M2AS1-6221-R/CE consists of three primary parts: 1. **The Plunger:** The interface between the external mechanical force and the internal spring. 2. **The Spring Mechanism:** A "snap-action" leaf spring that ensures the contacts move rapidly. This prevents "arcing" (electrical sparks) which can damage the switch over time. 3. **Contacts:** Usually made of silver alloy to ensure high conductivity and resistance to oxidation. ### 3. Safety and Compliance The suffix **"CE"** in the part number is a critical electronic designation: * **CE Marking:** Indicates the part meets European Union safety, health, and environmental protection requirements. * **RoHS Compliant:** The "R" often signifies compliance with the Restriction of Hazardous Substances (lead-free). --- ### 4. Common Applications * **Limit Switching:** Detecting when a machine part has reached the end of its travel. * **Safety Interlocks:** Ensuring a microwave door or industrial panel is closed before the circuit completes. * **Control Panels:** Used as a durable tactile button for human-machine interfaces. ---
