Commercial Induction Cooker 8-Level Knob Magnetic Control Switch Circuit Board
## 1. Product Overview
Our factory specializes in manufacturing circuit boards for commercial induction cookers featuring 8-position rotary magnetic control switches. Utilizing a DC5V Hall-effect contactless sensing solution, the rotary knob interface delivers uniform linear voltage output across 8 power levels. The system ensures stable gear recognition and maintains consistent performance without gear jumping or slipping, even in high-vibration kitchen environments with heavy steam and grease.

## II. Core Process Advantages
1. Contactless Hall Sensing
Eliminates traditional metal contacts by using magnetic sensing for gear switching, preventing common failures like oil contamination, oxidation, contact burnout, and gear malfunction. Service life is extended several times over.
2. Thickened Three-Proof PCB
Thickened fiberglass-copper clad substrate with full-panel nano-conformal coating for waterproof, oil-proof, and moisture-proof protection. Withstands high-temperature kitchen splashes and ensures stable operation without short circuits during continuous use.
3. Standard Linear Voltage Divider Curve
8 Power levels feature a clear gradient, with distinct settings for simmering, slow cooking, steaming, medium heat, stir-frying, high-heat stir-frying, searing, and intense frying. Smooth power transitions adapt to all culinary needs.
4. Interference-Resistant Industrial Design
Fully automated SMT assembly with widened conductive copper foil and built-in EMC interference suppression circuit. Designed for 380V high-power induction cooktops to ensure stable signal transmission without screen blackouts or interference issues.

## 3. Supported Devices
Compatible with commercial induction cooktops ranging from 6kW to 30kW: single and double wok burners, large pot stoves for cafeterias, soup kettles, noodle boilers, and concave high-power burners;
Designed for OEM production and replacement of old stoves. Features standard connector terminals for direct installation without stove modification.

## IV. Supply and After-Sales Service
1. In-stock bulk direct shipping; small-batch distribution and long-term supply for OEMs are all available.
2. Customization supported: voltage divider parameters, flex cable length, terminal definitions, and PCB silkscreen logos.
3. Factory-tested for 72 hours with power-on aging and high/low temperature simulation, ensuring a low defect rate.
4. Includes professional wiring guidance, stable warranty, and supply to cookware manufacturers, repair shops, and kitchen engineering contractors.
