Versatile 4-Position Selection: Features a precise 0-1-2-3 (OFF-1-2-3) indexing mechanism with 12 terminals. Specifically designed for synchronized 3-phase switching, providing high-efficiency control for multi-circuit industrial systems. Premium Silver Alloy & Safety Tip: Equipped with high-conductivity silver alloy contact points for superior electrical performance under heavy 40A loads. Industrial Grade Specifications: Rated for an Insulation Voltage Ui 660V and a robust Ith 40A Thermal Current. Constructed with reinforced flame-retardant PC housing to ensure maximum safety and low thermal buildup during long-term operation. Standard Panel Integration: Features a 65 x 65mm square faceplate designed for mounting on boards with a thickness of 1mm to 4mm. The robust internal build and standardized dimensions make it an ideal fit for heavy-duty control cabinets and machinery panels. Simplified Wiring Logic: Connect with confidence using this clear 3-phase matrix: In Position 1, terminals (1-2, 3-4) are connected. In Position 2, terminals (5-6, 7-8) are connected. In Position 3, terminals (9-10, 11-12) are connected. Position 0 serves as a complete system disconnect.

4 position control and 12 terminals design.

Suitable for the thickness between 1mm to 4mm of the mounting board.

Suitable for a wide range of applications, it can be applied as a circuit control switch, master control switch, testing equipment control switch, or change-over switch for electric welding machinery and other equipment.
