The **6SWVS-66-R** is a specific model of a **Miniature Tactile Switch** or **DIP Switch**, typically manufactured by companies like **DiPTronics** or similar specialized electronic component vendors. These are fundamental components in electronic circuits used for user input or hardware configuration. --- ## 1. Technical Specifications The following table outlines the typical electrical and mechanical characteristics of the 6SWVS-66-R series: | Parameter | Specification | | :--- | :--- | | **Switch Type** | Tactile Switch | | **Mounting Type** | Through-hole (Vertical) | | **Dimensions** | 6mm x 6mm | | **Actuation Force** | 160gf (Grams-force) | | **Contact Rating** | 50mA, 12V DC | | **Contact Resistance** | 100mΩ Max | | **Insulation Resistance** | 100MΩ Min at 500V DC | | **Dielectric Strength** | 250V AC for 1 minute | | **Life Cycle** | ~100,000 Cycles | --- ## 2. Structural Composition The part consists of four main electronic sub-components: 1. **Actuator (Button):** The top part that the user presses. In the "66" variant, this usually denotes a specific height (e.g., 5.0mm or 7.0mm depending on the manufacturer's datasheet). 2. **Contact Dome:** A metal snap-action disk that provides the "click" feel and completes the electrical circuit when compressed. 3. **Terminals:** Four metal pins designed to be soldered into a Printed Circuit Board (PCB). They are usually arranged in two pairs that are internally connected. 4. **Base/Housing:** Usually made of heat-resistant plastic (like Nylon or PPA) to withstand soldering temperatures. --- ## 3. Circuit Integration When integrating this part into a circuit, it is typically used as a **Normally Open (NO)** momentary switch. ### Example Schematic Connection To use this with a microcontroller (like an Arduino or ESP32), you would typically use a pull-up resistor configuration: ```c // Example Pseudo-code for reading the 6SWVS-66-R state int buttonPin = 2; // Pin connected to one terminal int buttonState = 0; void setup() { pinMode(buttonPin, INPUT_PULLUP); // Use internal resistor } void loop() { buttonState = digitalRead(buttonPin); if (buttonState == LOW) { // Switch is pressed } } ``` --- ## 4. Part Number Breakdown While naming conventions vary slightly by manufacturer, the code generally follows this logic: * **6S:** 6mm x 6mm Square base. * **WV:** Washable or Vertical orientation. * **S:** Surface Mount or specific Stem style. * **66:** Height code (Actuator length). * **R:** Packaging (often stands for "RoHS Compliant" or "Tape & Reel").
