The **SWT6-R1BTR** is a specific model of a **Tactile Switch** (commonly known as a tact switch). These are momentary push-button switches used in low-power applications to close an electrical circuit when pressed. --- ### 1. Technical Specifications Below are the typical electrical and mechanical characteristics for this series: | Parameter | Specification | | :--- | :--- | | **Switch Type** | Tactile (Momentary) | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Actuator Style** | Round Button | | **Circuit** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Contact Rating** | 50mA @ 12V DC | | **Operating Force** | 160gf (Grams-force) | | **Travel (Stroke)** | 0.25mm | | **Operating Life** | 100,000 Cycles | --- ### 2. Physical Dimensions The "6" in the part number usually refers to the base size of the switch. * **Base Size:** 6.0mm x 6.0mm. * **Height:** The specific height is designated by the suffix, but standard versions range from 4.3mm to 5.0mm. * **Packaging:** The "TR" in the suffix stands for **Tape and Reel**, indicating it is packaged for automated pick-and-place assembly machines. --- ### 3. Pin Configuration and Circuitry The SWT6-R1BTR typically features 4 pins. Internally, pins are connected in pairs to provide mechanical stability on the PCB. ```text [ Pin 1 ]----[ Pin 2 ] | | (Switch Mechanism) | | [ Pin 3 ]----[ Pin 4 ] ``` * **Operation:** When the button is pressed, the connection is made between the top pair (1 & 2) and the bottom pair (3 & 4). * **Feedback:** It provides "tactile feedback," meaning the user feels a physical "click" when the actuation point is reached. --- ### 4. Common Applications These switches are ubiquitous in consumer electronics due to their small footprint and reliability: * **User Interfaces:** Volume buttons on tablets or side buttons on smartphones. * **Peripherals:** Computer mice, keyboards, and printers. * **Industrial:** Reset buttons on PCBs and mode selection switches. * **Home Appliances:** Control panels for microwaves, washing machines, and coffee makers. ---
