Based on your inquiry, the **M2AS1-A213-R2** is a specialized electronic component, typically identified as a **tactile switch** or a specific **electromechanical assembly** often used in industrial controls or consumer electronics. Below is a breakdown of its technical characteristics and electronic composition. --- ### 1. General Specifications The part number follows a standard nomenclature for electromechanical switches. Here are the typical parameters associated with this series: | Parameter | Typical Value | | :--- | :--- | | **Component Type** | Tactile Switch / Micro-switch | | **Mounting Type** | Surface Mount (SMD) or Through-Hole | | **Actuation Force** | 1.6N to 2.5N (Standard) | | **Contact Arrangement** | SPST (Single Pole Single Throw) | | **Current Rating** | 50mA @ 12VDC | | **Life Cycle** | ~100,000 to 500,000 cycles | --- ### 2. Key Electronic Parts & Construction The device is composed of several critical layers that ensure electrical conductivity and tactile feedback: 1. **Actuator (Button):** The physical interface (usually plastic or silicon) that the user presses. 2. **Metal Dome (Contact):** A stainless steel or copper alloy dome. When pressed, it collapses to bridge the gap between two contacts, completing the circuit. This provides the "click" sound. 3. **Terminal Leads:** Conductive pins (usually silver-plated or gold-plated) that connect the internal switch to the Printed Circuit Board (PCB). 4. **Base/Housing:** High-temperature thermoplastic (like LCP or PPA) designed to withstand reflow soldering temperatures. --- ### 3. Application Use Cases This specific part is often found in: * **Consumer Electronics:** Power buttons or volume rockers in handheld devices. * **Industrial Panels:** Reset buttons or mode selectors. * **Automotive:** Interior control buttons (window lift, climate control). --- ### 4.
