The **M2AS1-5414-R** is a specific electronic component typically identified as a **tactile switch** or a low-profile push-button switch. These components are fundamental in human-interface devices for providing physical feedback when a circuit is closed. --- ### 1. Key Technical Specifications Based on the standard nomenclature for this series, here are the general technical parameters: | Parameter | Specification | | :--- | :--- | | **Type** | Tactile Switch (Momentary) | | **Mounting Type** | Surface Mount (SMT / SMD) | | **Circuit** | SPST (Single Pole Single Throw) | | **Actuation Force** | Typically 160gf to 250gf | | **Operating Life** | ~100,000 to 500,000 cycles | | **Contact Rating** | 50mA @ 12VDC (Common) | | **Operating Temp** | -25°C to +70°C | --- ### 2. Physical Construction The part is comprised of several distinct layers that work together to provide mechanical and electrical functionality: 1. **Actuator (Button):** The top part that the user presses. In the "R" variant (often denoting RoHS compliant or specific Reel packaging), the height is minimized for sleek devices. 2. **Cover/Frame:** A metal or plastic housing that protects the internal dome. 3. **Contact Dome:** A snap-action metal disc (usually stainless steel). This provides the "click" feel and bridges the gap between contacts when pressed. 4. **Base:** The plastic housing containing the terminal pins. 5. **Terminals:** Silver-plated or gold-plated leads designed for soldering onto a PCB. --- ### 3. Applications and Usage This part is commonly found in consumer electronics where space is at a premium and a tactile "click" is required: * **Mobile Devices:** Volume rockers or power buttons. * **Industrial Controls:** Reset switches on embedded boards. * **Peripherals:** Mouse buttons or keyboard function keys. * **Home Appliances:** Control panels for microwaves or coffee makers. --- ### 4. Schematic Representation In an electrical circuit, the M2AS1-5414-R functions as a "Normally Open" (NO) switch: ```text [Pin 1] ----/ ---- [Pin 2] (Press to Close) ``` ---
