The **W2PE-1AE-R2/UL** is a specific model of an **Industrial Toggle Switch** (commonly used in heavy-duty machinery and control panels). Below is a detailed breakdown of its electronic specifications and features. --- ### 1. General Specifications The part number indicates a high-performance, panel-mounted toggle switch designed for industrial durability. | Component Feature | Specification | | :--- | :--- | | **Type** | Toggle Switch | | **Circuitry** | SPST (Single Pole Single Throw) | | **Switch Function** | ON - OFF | | **Current Rating** | Typically 15A - 20A (depending on voltage) | | **Voltage Rating** | 125VAC / 250VAC | | **Mounting Type** | Panel Mount (Nut and Washer) | | **Certification** | UL Recognized (indicated by the /UL suffix) | --- ### 2. Detailed Technical Parts Breakdown #### **A. Actuator and Lever** * **Material:** Usually a chrome-plated brass or high-grade metal alloy. * **Design:** Heavy-duty bat-style handle for ease of operation with gloved hands. #### **B. Contact Mechanism** * **Material:** Silver-plated copper or silver-cadmium oxide. Silver is used to ensure high conductivity and to resist arcing under high-load switching. * **Spring System:** Uses a "Wiping" contact design, which helps clear oxidation from the contact surface every time the switch is toggled. #### **C. Housing and Insulation** * **Material:** Thermoset Phenolic or Polycarbonate base. * **Resistance:** Designed for high dielectric strength to prevent electrical tracking (arcing across the surface). #### **D. Termination (Wiring Connection)** * **Style:** Screw Terminals (indicated by the -R2 variant). * **Function:** Allows for secure mechanical connections of wires (usually ring or spade terminals), essential in high-vibration environments. --- ### 3. Key Differentiators * **Environmental Protection:** The "W" prefix often refers to "Weather-resistant" or "Waterproof" sealing (O-rings) inside the bushing to prevent moisture from entering the electronics. * **UL Approval:** The `/UL` ensures the switch meets Underwriters Laboratories safety standards for fire safety and electrical load management in North America. ### 4. Common Applications 1. **Industrial Machinery:** Power cut-off switches for motors. 2. **Marine Equipment:** Navigation lights or bilge pumps (due to environmental sealing). 3. **Automotive/Transport:** Auxiliary light controls or hydraulic controls.
