Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Air Pressure Control: Designed to regulate air pressure in systems such as spa jets, garbage disposers, and industrial machinery, ensuring safe and efficient operation.
  • Multi-Current Handling: Supports maximum current ratings of 3A, 5A, and 21A with SPST/SPDT contact arrangements, enabling versatility for low to high-power applications.

Key features

  • 1. Copper Contacts for Enhanced Durability

    • With copper contacts, ensure reliable electrical conductivity and corrosion resistance, outperforming switches with lower-quality materials like brass in harsh environments.*

  • 2. Versatile SPST/SPDT Contact Arrangements

    • With SPST (Single Pole Single Throw) and SPDT (Single Pole Double Throw) configurations, you can adapt to both simple and complex circuit needs, offering more flexibility than single-configuration switches.*

  • 3. High-Performance Current and Voltage Handling

    • With a maximum current of 21A and 250V rating, handle heavy-duty applications more effectively than standard switches rated at 15A/120V, ensuring stability in power-intensive systems.*

  • 4. Commercial-Grade Wet Environment Compatibility

    • Designed for food waste disposers, this switch ensures safe and efficient operation in damp or wet industrial settings, unlike general-purpose switches not rated for such conditions.*

  • 5. UL Certification for Safety and Compliance

    • With UL certification, meet North American safety and performance standards, guaranteeing reliability compared to non-certified alternatives.*
