The SZW26-324GS is a heavy-duty rotary power switch designed for high-current switching applications. Its core features a four-section (layer) structure, with eight sets of parallel silver alloy contacts (1-2 to 15-16) operating synchronously. In the "ON" position, all contacts are connected. This multi-contact parallel design significantly increases the conductive cross-section, effectively reducing contact resistance and temperature rise, and providing redundant contact protection. This ensures high current carrying stability and electrical life at a rated current of 32A. In the "OFF" position, all contacts are completely disconnected, providing a clear physical isolation point. The product uses thickened copper conductors and a high-strength flame-retardant casing, suitable for industrial environments 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 specifically designed for critical electrical circuits requiring stringent reliability, current carrying capacity, and long-term stability.
Core Application: Used as a main power isolation switch or main circuit disconnect switch for high-power industrial equipment (such as large motors, electric furnaces, rectifier power supplies, and heavy machinery).
