BAOMAIN 40A 660V 3-Position Momentary Rotary Cam Switch, 12 Terminal 1-0-2 SZW26-40/B303.3 for Motor Reversing, Industrial Control & Testing Equipment

Plastic external material, 3 positions,Momentary action type, 12 screw terminals, fit for 1.3cm panel thickness.Application: circuit control switch, master control switch, testing equipment control switch, or change-over switch for electric welding machinery and other equipment.Pro Tip for Safety: Due to the high amperage, please ensure all 12 screw terminals are tightened firmly during setup; loose connections are the primary cause of heat buildup and potential melting.

• Momentary Auto-Reset Action: Features a specialized 3-position (1-0-2) indexing mechanism with a spring-return function. The handle automatically flips back to the center 0 position when released, making it ideal for precise motor jogging and inching operations.
• Premium Silver Alloy & Safety Tip: Equipped with high-conductivity silver alloy contact points for superior electrical stability 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 high-frequency switching.
• Standard Panel Integration: Features a 66 x 66mm 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 machinery cabinets and control panels.
• Simplified 12-Terminal Logic: Connect with confidence using this clear 3-phase matrix: In Position 1 (-45°), terminals (1-2, 5-6, 9-10) are active. In Position 2 (+45°), terminals (3-4, 7-8, 11-12) are active. All circuits break instantly upon handle release.
