The **SWT6-R4NTR** is a specific type of **Tactile Switch** (or tact switch) commonly used in consumer electronics, instrumentation, and control panels. These are momentary push-button switches that provide tactile feedback to the user. Below is a detailed breakdown of its electronic and mechanical specifications. --- ## 1. Technical Specifications The SWT6 series is characterized by its compact form factor and Surface Mount Technology (SMT) compatibility. | Parameter | Typical Value | | :--- | :--- | | **Switch Type** | Momentary (Normally Open) | | **Mounting Style** | Surface Mount (SMD/SMT) | | **Footprint Size** | 6mm x 6mm | | **Current Rating** | 50mA | | **Voltage Rating** | 12V DC | | **Actuation Force** | Usually 160gf or 250gf (varies by suffix) | | **Contact Resistance** | < 100mΩ | | **Travel Distance** | 0.25mm ± 0.1mm | --- ## 2. Key Features & Construction The "R4NTR" suffix provides specific details about the physical packaging and height of the component: * **SMD Design:** Designed for automated "pick and place" assembly lines. The leads are bent outward (Gull-wing style) to sit on PCB pads. * **Tape & Reel (TR):** The "TR" at the end signifies that the parts are supplied on a Tape and Reel, which is essential for high-volume industrial manufacturing. * **Tactile Feedback:** The switch uses a metal dome internally. When pressed, the dome collapses to bridge the contacts, creating a "click" feel. * **Durability:** Most switches in this class are rated for **100,000 to 500,000 cycles**, depending on the materials used. --- ## 3. Pin Configuration (Typical) Most 6x6mm tact switches have 4 pins. Internally, these pins are connected in pairs. | Pin Pair | Function | | :--- | :--- | | **1 & 2** | Internally connected together | | **3 & 4** | Internally connected together | | **1/2 to 3/4** | The circuit is closed only when the button is pressed. | --- ## 4. Common Applications Due to its small size and reliability, the SWT6-R4NTR is found in: * **Consumer Electronics:** Remote controls, microwave ovens, and printers. * **Computer Peripherals:** Reset buttons on motherboards or function keys. * **Industrial:** Interface panels for PLC controllers. ---
