BAOMAIN 20A 660V 3-Position Changeover Switch, 12 Terminal 1-0-2 Selector SZW26-20/D303.3 for Motor Reversing, Generator Transfer & Industrial Power Control

BAOMAIN 20A 660V 3-Position Changeover Switch, 12 Terminal 1-0-2 Selector SZW26-20/D303.3 for Motor Reversing, Generator Transfer & Industrial Power Control

• Multi-Scene Application: Engineered for professional motor reversing, generator transfer, and manual power selection. The precise 1-0-2 (ON-OFF-ON) indexing mechanism ensures safe and synchronized circuit switching for industrial or workshop projects.
• Premium Silver Alloy & Installation Tip: Equipped with high-conductivity silver alloy contacts for efficient power transmission and oxidation resistance.
• Heavy-Duty Industrial Specs: Features a 660V Insulation Voltage (Ui) and a 20A Thermal Current (Ith). Constructed from reinforced flame-retardant PC material, it provides excellent heat resistance and high-temperature insulation safety under rigorous loads.
• Standard Panel Mounting: Designed for mounting boards with a thickness of 1mm to 4mm. The compact 50 x 50mm square faceplate and robust internal build make it ideal for integration into control cabinets and industrial automation panels.
• Simplified Wiring Logic: To assist with setup, the 12-terminal matrix follows a clear logic: In Position 1, terminals (1-2, 5-6, 9-10) are connected; in Position 2, terminals (3-4, 7-8, 11-12) are connected. Please refer to the Truth Table in our images for full schematic details.
