The **KWMS2-0G-R** is a specific electronic component, primarily recognized as a **Micro Switch** (specifically a Sub-miniature type) often used in precision control and sensing applications. Below is a detailed breakdown of its electronic specifications and features. --- ## 1. Component Overview The KWMS2-0G-R belongs to the category of **Snap-Action Switches**. These are mechanical switches that require very little physical force to actuate, providing a "snap" feel and sound that confirms the connection. | Attribute | Specification | | :--- | :--- | | **Type** | Sub-miniature Micro Switch | | **Actuator Style** | Pin Plunger (Standard) | | **Contact Form** | SPDT (Single Pole Double Throw) | | **Termination** | Solder Terminals / PCB Mount (Depending on exact sub-series) | | **RoHS Status** | Compliant (Indicated by the '-R' suffix) | --- ## 2. Electrical Specifications These parameters define the limits of the switch's operation within a circuit. * **Current Rating:** Typically rated between **0.1A to 5A** at 125/250VAC, depending on the contact material (Gold vs. Silver). * **Insulation Resistance:** Usually $\ge 100M\Omega$ at 500VDC. * **Contact Resistance:** $\le 30m\Omega$ to $50m\Omega$ (Initial). * **Dielectric Strength:** Capable of withstanding $1,000VAC$ for 1 minute between non-connected terminals. --- ## 3. Mechanical Characteristics The longevity and physical performance of the switch are governed by these mechanical factors: 1. **Operating Force (OF):** Requires a specific gram-force (e.g., $150g \pm 50g$) to compress the plunger. 2. **Release Force (RF):** The force the switch exerts to return to its rest position. 3. **Mechanical Life:** Generally rated for **1,000,000 cycles** or more. 4. **Electrical Life:** Generally rated for **10,000 to 100,000 cycles** at full load. --- ## 4. Part Number Breakdown (KWMS2-0G-R) While manufacturers vary slightly, the nomenclature typically follows this pattern: * **KWMS:** Series designation (Micro Switch). * **2:** Size or current rating code (Sub-miniature). * **0:** Actuator type (0 usually signifies a standard pin plunger). * **G:** Contact Material (often signifies **Gold plating**, ideal for low-current signal switching to prevent oxidation). * **R:** Compliance indicator (**RoHS** compliant). --- ## 5. Common Applications Due to its small footprint and reliability, this part is found in: * **Computer Peripherals:** Mouse buttons or keyboard switches. * **Industrial:** Limit switches for small CNC machines or 3D printers. * **Automotive:** Door latch sensing and seatbelt detection. * **Consumer Electronics:** Power buttons on microwave ovens or coffee makers. ---
