The **KWTS-62B-R** is a specific model of a **Tactile Switch** (also known as a momentary push-button switch). These components are widely used in consumer electronics, automotive interfaces, and industrial controls due to their small footprint and tactile feedback. --- ## 1. Technical Specifications Below are the typical electronic and physical specifications for the KWTS-62B-R series: | Parameter | Specification | | :--- | :--- | | **Switch Type** | Tactile (Momentary) | | **Mounting Type** | Through-hole (DIP) | | **Contact Arrangement** | SPST (Single Pole Single Throw) | | **Operating Force** | 160gf ± 50gf (Standard) | | **Contact Rating** | 50mA, 12V DC | | **Insulation Resistance** | 100MΩ min. at 100V DC | | **Dielectric Strength** | 250V AC for 1 minute | | **Travel (Stroke)** | 0.25mm ± 0.1mm | --- ## 2. Component Structure The "B-R" designation usually refers to specific physical attributes: * **KWTS-62:** Refers to the series size, typically **6x6mm** square base. * **B:** Often denotes the height of the plunger (stem). In this series, "B" usually corresponds to a specific height (e.g., 5.0mm), though this can vary by manufacturer. * **R:** Generally signifies **Red** actuator color or **RoHS** compliance, depending on the specific vendor's datasheet. ### Internal Parts: 1. **Cover:** Metal plate protecting the internal mechanism. 2. **Contact Dome:** A circular metal disc that provides the "click" feel and completes the circuit when pressed. 3. **Base:** Heat-resistant plastic (usually LCP or PPA). 4. **Terminals:** Four pins (internally connected in pairs) for PCB mounting. --- ## 3. Circuit Diagram The switch functions as a simple bridge. When the button is pressed, the internal dome collapses and connects the input pins to the output pins. ```text Pin 1 ----| |---- Pin 2 | | <-- Internal Connection Pin 3 ----| |---- Pin 4 ``` *Note: Usually, Pin 1-2 are connected and Pin 3-4 are connected internally. Pressing the switch connects 1-2 to 3-4.* --- ## 4. Common Applications * **Computer Peripherals:** Reset buttons, power buttons. * **Household Appliances:** Microwave panels, washing machine controls. * **Instrumentation:** Digital multimeters, oscillators. * **Consumer Electronics:** Remote controls, toys. ---
