The **KWTS-2BC-R/BL** is a specific model of a **Push Button Switch**, commonly utilized in consumer electronics, automotive interiors, and industrial control panels. It is known for its compact design and integrated LED illumination. --- ## 1. Technical Specifications Below are the primary electrical and physical characteristics of the KWTS-2BC-R/BL: | Parameter | Specification | | :--- | :--- | | **Switch Type** | Momentary Push Button | | **Circuit Configuration** | SPST (Single Pole Single Throw) | | **Rated Voltage/Current** | 12V DC / 50mA | | **Illumination Color** | Red (R) / Blue (BL) Dual-color or bi-color option | | **Mounting Type** | Through-hole (PCB Mount) | | **Contact Resistance** | $\leq$ 100m$\Omega$ | | **Insulation Resistance** | $\geq$ 100M$\Omega$ (at 250V DC) | | **Operating Force** | 160g $\pm$ 50g | --- ## 2. Key Components & Construction The part is comprised of several critical sub-components that define its functionality: ### A. The Actuator (Stem) The "button" part of the switch. In the **R/BL** series, this is usually translucent or transparent to allow the internal LED light to diffuse evenly through the cap. ### B. LED Integration The "R/BL" suffix indicates the lighting configuration: * **R:** Red LED. * **BL:** Blue LED. * The switch contains four or more pins: two for the switch circuit and two (or three for common cathode/anode) for the internal LEDs. ### C. Contact Dome A precision-engineered metal dome (usually stainless steel or copper alloy) that provides the "tactile" click feel. When pressed, it bridges the gap between PCB traces to close the circuit. --- ## 3. Pinout Configuration While specific layouts can vary by manufacturer, the standard 6-pin layout for an illuminated tactile switch like this usually follows this logic: ```text Pin 1 & 2: Switch Contact (Normally Open) Pin 3 & 4: LED 1 (Red) Anode/Cathode Pin 5 & 6: LED 2 (Blue) Anode/Cathode ``` --- ## 4. Typical Applications * **Audio/Video Equipment:** Used as "Play/Stop" or "Selection" buttons where status feedback (via light) is required. * **Medical Devices:** Compact interfaces where visual confirmation of a "power on" state is necessary. * **Custom Keyboards/Macro Pads:** Integrated into PC peripherals for aesthetic and functional signaling.
