The AN12C AC Motor Speed Control Switch is designed for variable speed regulation in AC motor applications.
Compliant with EN61058-1 safety standard, AN12C supports AC250V voltage and 6(6)A current rating, providing reliable speed adjustment solutions for electric tools, small appliances, and motor-driven equipment.
With compact design and stable control performance, AN12C is suitable for OEM manufacturers requiring integrated speed control switches.
Continuous motor speed control from the rotary dial — adjust cutting and sanding speed to the material.
Certified to IEC/EN 61058-1 standard for switches — meets stringent international safety requirements.
IP00 rated enclosure — designed for integration inside sealed tool housings for additional protection.

Contact UsThe AN12C is an AC speed control switch (speed control board) for variable speed regulation in AC motor applications. It is used in electric tools, small appliances and motor-driven equipment, and fits AC-powered power tools when it is wired between the trigger switch and the motor.
The AN12C supports AC 250V with a 6(6)A rated current and a rated power range of 50-550W. It is certified to IEC/EN 61058-1, the switch standard it complies with.
The AN12C is an IP00-rated board, designed for integration inside sealed tool housings that provide the additional protection. It should therefore be mounted inside the machine enclosure rather than exposed.
The PCB measures 68 � 21.4 mm, with a thickness of 1.5 mm and a height of 20.5 mm. Four leads are used: black 16AWG (live input), red 16AWG (live output), white 20AWG (neutral common) and blue 20AWG (neutral input), wired to AC 250V.
Speed is adjusted continuously with the rotary dial, so the operator can match cutting and sanding speed to the material. The control performs AC speed regulation across the rated power range of 50-550W.
