The **SWT8-R1NTR** is an electronic component primarily categorized as a **Tactile Switch**. These are momentary push-button switches commonly used in low-power applications to provide tactile feedback to the user. --- ### 1. General Specifications The following table outlines the typical technical parameters for the SWT8 series: | Parameter | Specifications | | :--- | :--- | | **Switch Type** | Tactile (Momentary) | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Actuation Direction** | Vertical (Top Actuated) | | **Contact Arrangement** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Operating Force** | Typically 160gf to 250gf | | **Dimensions** | 6mm x 6mm (Base) | | **Travel** | 0.25mm ± 0.1mm | --- ### 2. Physical Construction The part number "SWT8-R1NTR" can be broken down into its structural components: * **Housing:** Usually made of high-temperature resistant thermoplastic (LCP or Nylon) to withstand reflow soldering. * **Terminals (R1):** Refers to the lead configuration, designed for surface mounting with "Gull-wing" style leads. * **Actuator:** The "Stem" or button part. The height varies, but it is typically made of plastic or silicon. * **Contact Dome:** A stainless steel or phosphor bronze dome that provides the "click" feel and completes the electrical circuit. * **Packaging (TR):** Indicates **Tape & Reel** packaging, which is essential for automated pick-and-place assembly lines. --- ### 3. Electrical Characteristics Despite its small size, the electrical performance is critical for signal integrity: 1. **Contact Rating:** Maximum 50mA at 12V DC. 2. **Contact Resistance:** Usually < 100mΩ (Initial). 3. **Insulation Resistance:** > 100MΩ at 100V DC. 4. **Dielectric Strength:** 250V AC for 1 minute. 5. **Operating Life:** Rated for 50,000 to 100,000 cycles depending on the specific force rating. --- ### 4. Common Applications Due to its compact SMT footprint, the SWT8-R1NTR is found in: * **Consumer Electronics:** Remote controls, headphones, and cameras. * **Computing:** Mouse buttons, reset switches on PCBs. * **Industrial:** Interface panels and handheld testing equipment. * **Automotive:** Dashboard controls and key fobs.
