The SZW26-32/3GS is a rotary power switch with a three-section (layer) design, specifically engineered for on/off control. Its core feature is the use of three independent contact layers, totaling six pairs (1-2 to 11-12) of silver alloy contacts working in parallel. These contacts are simultaneously connected in the "ON" position, significantly increasing current carrying capacity and distributing arc and heat, ensuring long-term stability and contact reliability at a rated current of 32A. In the "OFF" position, all contacts are completely disconnected, providing a clear electrical isolation point. The product features thickened copper components and a flame-retardant, high-temperature resistant housing, meeting industrial environment requirements from -25°C to +40°C, with a mechanical life of 100,000 cycles and an electrical life of 30,000 cycles.
Application Scenarios
This switch is suitable for applications requiring high current capacity and high-reliability switching performance, particularly as a main power isolation switch or load control switch for high-power equipment.
Core Applications: As a main power input switch or main circuit disconnect switch for high-power motors (such as fans, water pumps, compressors), industrial electric heating equipment, large power cabinets, and distribution boxes.
Key Advantage Scenarios: In vibrating environments, frequent start-stop cycles, or circuits requiring extremely high contact reliability, its multi-contact parallel design provides redundancy, superior to ordinary single-section or double-section switches.
