The **WRPPB-KAM5N-R** is a specific part number typically associated with professional-grade **Push Button Switches**, often used in industrial control panels or specialized electronics. Based on the nomenclature, this component belongs to a series of ruggedized, illuminated, or waterproof switches. ### 1. Component Specifications Below is a breakdown of the typical technical characteristics for this type of electronic part: | Parameter | Specification | | :--- | :--- | | **Component Type** | Push Button Switch | | **Circuit Configuration** | SPST (Single Pole Single Throw) or DPDT | | **Actuation Type** | Momentary (Spring Return) or Latching | | **Voltage Rating** | Usually 12V - 24V DC / 125V - 250V AC | | **Current Rating** | 2A to 5A (typical for control signals) | | **Contact Material** | Silver Alloy or Gold-plated | | **Termination Style** | Solder Lug or Screw Terminals | | **IP Rating** | Often IP65 or IP67 (Waterproof/Dustproof) | --- ### 2. Breakdown of the Part Number (Naming Convention) While specific to the manufacturer (often associated with brands like **Well Buying** or similar industrial suppliers), the code usually breaks down as follows: * **WRPPB**: Series identifier (Waterproof Round Push Button). * **KA**: Actuator style (often refers to a flat or high-head button). * **M5**: Mounting size (e.g., 16mm, 19mm, or 22mm diameter hole). * **N**: Contact arrangement (Normally Open or Normally Closed). * **R**: LED Color / Cap Color (Red). --- ### 3. Key Features * **Environmental Protection:** Designed with an internal O-ring to prevent moisture and dust ingress, making it suitable for outdoor or marine environments. * **Illumination:** The "R" suffix often indicates a Red LED ring or power symbol illumination, requiring a specific resistor for the LED circuit. * **Durability:** Mechanical life is typically rated for over 1,000,000 cycles, and electrical life for 50,000+ cycles. * **Housing:** Usually constructed from stainless steel, nickel-plated brass, or high-strength polycarbonate. --- ### 4. Typical Wiring Diagram The part usually features 4 or 5 pins: two for the switch contacts and two/three for the LED illumination. ```cpp // Schematic Representation [Pin 1] ---- (Switch Common) [Pin 2] ---- (Normally Open Contact) [Pin +] ---- (LED Anode +) [Pin -] ---- (LED Cathode -) ```
