Based on the part number **W2PP-92YR-R**, this component is a **miniature push-button switch** typically manufactured by companies like **NKK Switches** or similar electronic component vendors. Below is a detailed breakdown of its specifications and electronic characteristics. --- ### 1. Component Overview The W2PP series represents a line of compact, high-reliability push-button switches designed for PCB (Printed Circuit Board) mounting. The "-R" suffix usually denotes compliance with **RoHS** environmental standards. ### 2. Technical Specifications | Feature | Specification | | :--- | :--- | | **Switch Type** | Push-button | | **Circuit Type** | SPDT (Single Pole Double Throw) | | **Switch Function** | Momentary (On) - Mother spring returns to original position | | **Contact Rating** | Usually 0.4VA Max @ 28V AC/DC (Logic Level) | | **Termination Style** | PC Pins (Through-hole) | | **Actuator Style** | Plunger / Button | | **Operating Force** | ~1.5 to 2.5 Newtons | | **Mechanical Life** | ~50,000 to 100,000 Cycles | --- ### 3. Key Electronic Characteristics * **Logic Level Contacts:** These switches are generally designed for "logic level" applications. They often use gold-plated contacts to ensure reliable switching in low-voltage, low-current circuits where oxidation could otherwise cause signal failure. * **Bounce Time:** As a mechanical switch, it will exhibit a "bounce" period (typically <5ms). In digital circuits, software or hardware **debouncing** is required. * **Dielectric Strength:** Usually rated to withstand 1,000V AC for one minute, ensuring insulation between the contacts and the casing. * **Insulation Resistance:** Typically 1,000 Megohms minimum at 500V DC. ### 4. Typical Applications * **Consumer Electronics:** Reset buttons or mode selection. * **Industrial Controls:** Low-power signal switching in handheld devices. * **Medical Equipment:** Interface buttons on diagnostic tools. * **Telecommunications:** Configuration switches on networking hardware. --- ### 5. Circuit Symbol (SPDT) The internal wiring for this part follows the SPDT configuration: ```text [Common] ----/ ---- [NC - Normally Closed] | +------ [NO - Normally Open] ```
