The **SWT6-R8RTR** is a specific electronic component, typically categorized as a **Tactile Switch** (or Micro Switch) often used in consumer electronics, automotive interfaces, and industrial controls. Below is a detailed breakdown of its electronic specifications and characteristics. --- ### 1. General Specifications The SWT6 series generally refers to 6x6mm square tactile switches. The "R8RTR" suffix defines its physical orientation, operating force, and packaging. | Feature | Specification (Typical) | | :--- | :--- | | **Type** | Tactile Switch (Momentary) | | **Dimensions** | 6.0mm x 6.0mm | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Actuator Height** | 5.0mm (Standard for R8 series) | | **Operating Force** | 160gf to 260gf (Grams-force) | | **Contact Arrangement** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Packaging** | Tape & Reel (TR) | --- ### 2. Electrical Characteristics These parameters define the limits under which the switch can safely operate without damage or electrical failure. * **Contact Rating:** Usually rated at **50mA / 12V DC**. It is designed for logic signals, not for high-power switching. * **Contact Resistance:** Typically less than **100mΩ** (initial). * **Insulation Resistance:** Minimum of **100MΩ** at 100V DC. * **Dielectric Strength:** 250V AC for 1 minute. * **Bounce Time:** Usually **<10ms** (important for software debouncing in microcontrollers). --- ### 3. Mechanical & Environmental Properties * **Life Expectancy:** Generally rated for **100,000 to 500,000 cycles**, depending on the specific material used for the internal dome. * **Operating Temperature:** Typically ranges from **-25°C to +70°C**. * **Travel:** The vertical distance the button moves before making contact, usually **0.25mm ± 0.1mm**. --- ### 4. Part Number Breakdown (SWT6-R8RTR) While naming conventions vary slightly by manufacturer (like Diptronics or generic clones), the code usually breaks down as follows: 1. **SWT6:** The series family (6x6mm size). 2. **R8:** Defines the actuator height and shape (Right angle or vertical stem height). 3. **R:** Often indicates "Red" or a specific operating force/material. 4. **TR:** Stands for **Tape & Reel**, indicating the part is packaged on a reel for automated Pick-and-Place assembly. --- ### 5. Common Applications * **Consumer Electronics:** Power buttons on routers, monitors, or remote controls. * **Embedded Systems:** Reset buttons on PCBs (Arduino, ESP32 boards). * **Automotive:** Dash buttons and climate control interfaces.
