## Technical Overview of M2PHSW-23-R2/N The **M2PHSW-23-R2/N** is a specific model within a series of industrial-grade **Tactile Switches** (often referred to as Push Switches). These components are primarily used in consumer electronics, automotive dashboards, and industrial control panels where a tactile "click" feedback is required. --- ### 1. Key Technical Specifications Based on the standard nomenclature for this series, here are the primary electrical and mechanical specifications: | Feature | Specification | | :--- | :--- | | **Switch Type** | Momentary Push Button (Tactile) | | **Circuit Configuration** | SPST (Single Pole Single Throw) | | **Current Rating** | 50mA to 100mA (typical for signal level) | | **Voltage Rating** | 12V DC to 24V DC | | **Contact Resistance** | ≤ 100 mΩ | | **Insulation Resistance** | ≥ 100 MΩ (at 250V DC) | | **Operating Force** | 160gf to 250gf (grams-force) | | **Life Expectancy** | ~100,000 Cycles | --- ### 2. Component Structure and Materials The "R2/N" suffix often denotes specific mounting and material variations. The internal electronic parts include: 1. **Actuator (Button):** The top part pressed by the user. In the "R2" variant, this is usually a raised stem to accommodate a keycap. 2. **Contact Dome:** A precision-engineered metal alloy (often stainless steel or phosphor bronze) that snaps down to complete the circuit, providing the tactile "click." 3. **Terminals:** Silver-plated brass or copper. The "/N" often indicates a **Through-Hole** mounting style (standard pins) rather than Surface Mount (SMD). 4. **Base/Housing:** High-temperature resistant thermoplastic (e.g., LCP or PBT) capable of withstanding wave soldering. --- ### 3. Electronic Functionality The M2PHSW-23-R2/N acts as a **Normally Open (NO)** switch. * **State 1 (Idle):** The internal metal dome is arched, preventing electrical flow between the input and output pins. * **State 2 (Pressed):** The actuator pushes the dome down. The dome flattens, bridging the gap between the internal contacts. * **State 3 (Released):** The dome's elasticity causes it to spring back to its original shape, instantly breaking the circuit. --- ### 4. Typical Applications * **Control Panels:** Start/Stop or Reset buttons. * **Consumer Electronics:** Volume controls, power buttons on appliances. * **Interface Modules:** Used on PCB boards for mode selection or user input.
