The **W2PV-C2SB1-R** is a specific part number belonging to the **W2PV** series of miniature tactile switches manufactured by **Omron Electronic Components**. This component is designed for Surface Mount Technology (SMT) and is characterized by its extremely low profile and side-actuated mechanism. --- ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Switch Type** | Tactile Switch (Momentary) | | **Mounting Type** | Surface Mount (SMT) / Side-actuated | | **Contact Form** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Operating Force** | 1.6 N {approx. 163 gf} | | **External Dimensions** | 2.5 × 1.6 × 1.0 mm (Ultra-compact) | | **Actuator Type** | Side-push (Side-actuated) | | **Operating Life** | 100,000 operations (minimum) | | **Rated Voltage/Current** | 1 to 50 mA, 3 to 12 VDC | --- ### Key Electronic & Physical Characteristics 1. **Ultra-Miniature Design:** With a height of only 1.0 mm, this switch is ideal for high-density mounting in slim electronic devices. 2. **Side-Actuated Mechanism:** Unlike traditional "top-push" switches, this part is triggered from the side. This is essential for devices where the button must be on the edge of a PCB (like volume buttons on a smartphone). 3. **Gold-Plated Contacts:** Typically features high-quality plating to ensure low contact resistance and high reliability over the component's lifespan. 4. **Environmental Protection:** Designed to withstand high-temperature lead-free reflow soldering processes. ### Common Applications Due to its small footprint and side-actuation, the W2PV-C2SB1-R is commonly found in: * **Mobile Devices:** Smartphones, tablets, and smartwatches (power/volume buttons). * **Wearables:** Fitness trackers and medical monitoring devices. * **Portable Audio:** Bluetooth headsets and MP3 players. * **Compact Consumer Electronics:** Digital cameras and handheld gaming consoles. --- ### Schematic Representation The electronic logic of this switch is simple: it remains "Open" (no current flows) until the button is pressed, which closes the circuit temporarily. ```text [ Terminal A ] | ______|______ | | [Button] --> [ Contact ] |______ ______| | [ Terminal B ] ```
