The **KMS-6-R/CE** is a specific electronic component typically categorized as a **Surface Mount (SMT) Micro Switch** or tactile switch, often utilized in consumer electronics, automotive interfaces, and industrial controls. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The KMS series is known for being a side-actuated, low-profile tactile switch. The suffix "R" usually denotes "Right Angle" mounting, and "CE" refers to specific contact materials or compliance standards. | Feature | Specification | | :--- | :--- | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Orientation** | Side-Actuated (Right Angle) | | **Switch Function** | Momentary (Normally Open - NO) | | **Operating Force** | Typically 1.6N to 4N (depending on sub-variant) | | **Contact Rating** | 50 mA @ 32 V DC | | **Lifetime** | Up to 100,000 cycles | --- ### 2. Key Electronic Components & Materials The internal construction of the KMS-6-R/CE ensures reliability in small-footprint designs: * **Contacts:** Usually gold-plated or silver-plated to ensure low contact resistance and prevent oxidation. * **Actuator:** A miniature plunger designed for tactile feedback (the "click" sensation). * **Housing:** High-temperature thermoplastic capable of withstanding lead-free reflow soldering processes. * **Terminals:** "Gull-wing" or J-bend leads for secure SMT soldering to the PCB. --- ### 3. Dimensional Profile One of the primary reasons for selecting this part is its physical footprint: * **Compact Design:** Designed for tight spaces where height is limited. * **Side Actuation:** Allows the user to press the button from the edge of a PCB rather than from the top. --- ### 4. Typical Applications The KMS-6-R/CE is found in devices requiring a high-quality user interface in a small form factor: 1. **Consumer Electronics:** Volume buttons on smartphones or tablets. 2. **Medical Devices:** Handheld diagnostic tools. 3. **Automotive:** Key fobs, steering wheel controls, or dashboard interfaces. 4. **Industrial:** Reset switches on embedded circuit boards. --- ### 5. Soldering & Environmental * **RoHS Compliant:** The "CE" designation often aligns with European compliance for hazardous substances. * **Reflow Compatibility:** Designed to withstand standard IR reflow soldering temperatures (approx. 260°C).
