The **KWTS-6BC-R** is a specific electronic component typically identified as a **tactile switch** (or tact switch). These are momentary push-button switches commonly used in low-voltage, low-current signal circuits. --- ### 1. General Specifications The "KWTS" series generally follows industry standards for miniature switches. Below is a breakdown of the typical technical parameters for this part: | Parameter | Typical Value | | :--- | :--- | | **Switch Type** | Tactile (Momentary) | | **Circuit Configuration** | SPST-NO (Single Pole Single Throw, Normally Open) | | **Contact Rating** | 50mA @ 12V DC | | **Contact Resistance** | ≤ 100mΩ | | **Insulation Resistance** | ≥ 100MΩ (100V DC) | | **Operating Force** | 160gf to 250gf (Commonly 160gf) | | **Operating Life** | 100,000 to 500,000 cycles | --- ### 2. Physical Characteristics The suffix codes in the part number often refer to the physical dimensions and mounting styles: * **Size (6x6mm):** The "6" usually indicates a base size of 6mm x 6mm, which is the most common footprint for through-hole tact switches. * **Stem Height:** The "B" or "C" segments often denote the height of the plunger (the part you press). Height can range from 4.3mm to 9.5mm depending on the specific revision. * **Terminal Type:** This part typically features **Through-Hole Technology (THT)** pins, allowing it to be soldered into holes on a PCB. * **Color/Material:** The "R" may signify a specific color for the plunger (Red) or a specific packaging type (like "Reel" for SMD versions, though this specific model is usually THT). --- ### 3. Internal Schematic The switch acts as a simple bridge. When the plunger is pressed, a metal dome collapses to connect the internal terminals. ```text Pin 1 ----| |---- Pin 2 | | (Push to Close) Pin 3 ----| |---- Pin 4 ``` *Note: Usually, Pins 1 & 2 are internally connected, and Pins 3 & 4 are internally connected.* --- ### 4. Common Applications Due to its small size and reliability, the KWTS-6BC-R is found in: * **Consumer Electronics:** Remote controls, microwave panels, and digital cameras. * **Industrial:** Reset buttons on motherboards or PLC interfaces. * **DIY/Prototyping:** Breadboard-friendly buttons for Arduino and Raspberry Pi projects. ---
