The **KMMLS-1C1-R** is a specific model of a microswitch, typically categorized under subminiature snap-action switches. These components are designed to open or close an electrical circuit with very little physical force or travel distance. --- ### 1. Key Technical Specifications Below are the typical technical parameters associated with this class of electronic switch: | Parameter | Specification (Typical) | | :--- | :--- | | **Switch Type** | Subminiature Snap Action | | **Circuitry** | SPDT (Single Pole Double Throw) | | **Current Rating** | 1A to 3A (depending on DC/AC voltage) | | **Voltage Rating** | 125VAC / 30VDC | | **Actuator Type** | Pin Plunger / Simulated Roller | | **Termination Style** | PCB Terminals (Right Angle or Straight) | | **Operating Force** | ~150gf (Grams-force) | --- ### 2. Functional Components The "Electronic Parts" within this assembly consist of several mechanical and conductive elements that work in unison: * **The Contacts:** Usually made of silver alloy or gold-plating to ensure low electrical resistance and prevent oxidation. * **The Spring Mechanism:** A beryllium copper or stainless steel leaf spring that provides the "snap" action, ensuring the transition between contacts happens rapidly regardless of the speed of the external physical push. * **The Housing:** A thermoset or high-temperature thermoplastic casing that provides electrical insulation and structural integrity. * **Terminals:** Metal pins (usually brass with tin plating) that extend outside the housing to be soldered onto a Printed Circuit Board (PCB). --- ### 3. Connection Diagram (SPDT) The KMMLS-1C1-R typically follows the SPDT logic, which involves three pins: ```text Pin 1: COM (Common) - The input power/signal Pin 2: NC (Normally Closed) - Connected to COM when the switch is idle Pin 3: NO (Normally Open) - Connected to COM when the switch is pressed ``` ### 4. Typical Applications * **Computer Peripherals:** Mouse buttons or keyboard switches. * **Consumer Electronics:** Power buttons or detection sensors in small appliances. * **Industrial:** Limit switches for small-scale robotics or 3D printers.
