The **M2PHS2W-1C-R** is a specific part number typically associated with high-precision, small-form-factor electronic components, most commonly identified as a **Micro-Switch** or a **Tactile Limit Switch**. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications This part is designed for PCB mounting and is used in applications requiring tactile feedback and high reliability. | Feature | Specification | | :--- | :--- | | **Component Type** | Micro-Switch / Snap Action Switch | | **Contact Configuration** | SPDT (Single Pole Double Throw) | | **Switching Function** | 1C (Changeover) | | **Terminal Type** | Solder Terminals / Through-hole | | **Mounting Style** | PCB Mount | | **Actuator Type** | Pinhole / Plunger (W-type variant) | --- ### 2. Electrical Characteristics The internal electronics are designed to handle signal-level currents or low-power control circuits. * **Contact Rating:** Usually rated for **3A to 5A at 125/250VAC** (depending on the specific sub-series manufacturer). * **Contact Resistance:** Typically less than **30mΩ** (initial). * **Insulation Resistance:** Minimum **100MΩ** at 500VDC. * **Dielectric Strength:** Capable of withstanding **1000VAC** for 1 minute between non-consecutive terminals. --- ### 3. Mechanical & Environmental Properties The "R" suffix often denotes specific compliance or packaging (like RoHS compliance or Tape & Reel). * **Operating Force (OF):** High sensitivity, usually requiring between **50g to 150g** of force to actuate. * **Durability:** * Mechanical life: > 1,000,000 cycles. * Electrical life: > 100,000 cycles at full load. * **Operating Temperature:** Typically rated from **-25°C to +85°C**. --- ### 4. Pinout Configuration (1C Style) As a "1C" (SPDT) switch, it features three distinct electrical contact points: 1. **COM (Common):** The input terminal. 2. **NC (Normally Closed):** Connected to COM when the switch is at rest. 3. **NO (Normally Open):** Connects to COM only when the actuator is pressed. --- ### 5. Common Applications * **Computer Peripherals:** Mouse buttons or printer limit sensors. * **Industrial Automation:** End-stop sensors for CNC machines or 3D printers. * **Consumer Electronics:** Safety interlocks for small appliances. * **Automotive:** Door latch or seatbelt detection signals.
