The **M2PHSW-1D-R** is a specific electronic component typically identified as a **Micro-Miniature Slide Switch**. These switches are designed for compact electronic devices where space is at a premium and a physical "on/off" or "state-selection" mechanism is required. --- ### 1. General Specifications The following table outlines the typical technical parameters for this type of slide switch: | Feature | Specification | | :--- | :--- | | **Switch Type** | Slide Switch | | **Circuit Configuration** | SPDT (Single Pole Double Throw) | | **Switch Function** | On-On (or On-Off depending on wiring) | | **Mounting Type** | Through-Hole (Right Angle / Vertical options) | | **Contact Rating** | Usually 0.3A @ 6V DC or 0.1A @ 12V DC | | **Termination Style** | PC Pin (Solder) | | **Actuator Type** | Side or Top Actuated | --- ### 2. Physical Construction The part number breakdown often reveals the construction style: * **M2P Series:** Refers to the micro-miniature form factor. * **HSW:** Indicates a Horizontal Slide Switch (Side-actuated). * **1D:** Refers to the circuit logic (Single Pole). * **R:** Usually denotes "Right Angle" orientation or "RoHS" compliance depending on the manufacturer’s datasheet prefix. --- ### 3. Internal Circuit (SPDT) A Single Pole Double Throw (SPDT) switch has three pins. When you move the slider, you connect the center pin (Common) to one of the two outer pins. ```text [ Slider ] | | (1)-------(2)-------(3) Pin 1 Common Pin 2 ``` * **Position A:** Pin 2 (Common) is connected to Pin 1. * **Position B:** Pin 2 (Common) is connected to Pin 3. --- ### 4. Common Applications Due to its small footprint, the M2PHSW-1D-R is commonly found in: 1. **Handheld Devices:** Power switches for small toys, MP3 players, or voice recorders. 2. **Wearables:** Mode selection for fitness trackers or smart accessories. 3. **Prototyping:** Often used on breadboards or small PCBs (Printed Circuit Boards) for logic level switching. 4. **Configuration:** Serving as a "DIP switch" alternative to set hardware addresses or modes on a circuit. --- ### 5. Installation Note When soldering the M2PHSW-1D-R, it is important to avoid excessive heat. Because the body is made of plastic/thermoplastic, overheating the pins can melt the internal housing and cause the switch to jam or fail.
