The **KWMS2-DZ-R** is an electronic component primarily classified as a **surface-mount (SMD) tact switch** or a specific type of **micro-switch**. While part numbering can vary slightly between manufacturers (commonly associated with brands like Diptronics or similar regional electronics suppliers), it typically follows a standard profile for user-interface buttons. ### 1. Key Technical Specifications The following table highlights the typical electronic and mechanical characteristics of the KWMS2-DZ-R series: | Parameter | Typical Value | Unit | | :--- | :--- | :--- | | **Circuit Type** | SPST (Single Pole Single Throw) | - | | **Mounting Type** | SMD (Surface Mount Device) | - | | **Switch Function** | Momentary (Normally Open) | - | | **Contact Rating** | 50mA @ 12V DC | - | | **Operating Force** | 160gf to 250gf (Depending on sub-variant) | Gram-force | | **Travel distance** | 0.25 ± 0.1 | mm | | **Life Cycle** | 100,000 to 500,000 | Cycles | --- ### 2. Physical & Material Composition The "DZ" and "R" suffixes in the part number usually provide details regarding the physical orientation and packaging: * **D/DZ:** Often refers to the specific height of the actuator (the button part) or a "Side Actuated" (Right Angle) orientation. * **R:** Generally stands for **Tape and Reel** packaging, indicating it is designed for automated pick-and-place assembly lines. * **Contacts:** Usually silver-plated or gold-plated copper alloy to ensure low contact resistance. * **Base/Cover:** High-temperature thermoplastic (LCP or Nylon) to withstand reflow soldering temperatures. --- ### 3. Common Applications Because of its small footprint and tactile feedback, this part is found in: 1. **Consumer Electronics:** Volume buttons on smartphones, Bluetooth headsets, and digital cameras. 2. **Computing:** Reset buttons on motherboards or peripheral input devices. 3. **Industrial:** Handheld testing equipment and interface panels. --- ### 4. Schematic Representation In an electronic circuit, the part is represented as follows: ```text (Terminal 1) ----/ ---- (Terminal 2) (Switch) ``` *When the actuator is pressed, the circuit closes (ON); when released, the internal spring returns it to the open position (OFF).*
