Centrifugal Switches

Product Details:

An Electrical Motor Centrifugal Switch is a speed-sensitive mechanical switch used in single-phase induction motors to automatically control the starting winding or capacitor circuit. It ensures proper motor startup by keeping the starting circuit engaged during initial rotation and disconnecting it once the motor reaches the desired speed (typically 70–80% of full speed).

Built with precision-engineered metal and insulating components, the centrifugal switch operates through a centrifugal mechanism mounted on the motor shaft, providing reliable, automatic switching without external controls.

Key Features:

• Automatically connects and disconnects the starting winding or capacitor

• Accurate speed sensing for smooth motor operation

• Made from durable, heat-resistant materials

• Long service life with low maintenance

• Available for various motor power ratings and RPM ranges

Applications:
Widely used in single-phase induction motors for air compressors, pumps, washing machines, woodworking machinery, and other motor-driven equipment to ensure safe and efficient startup.

Product Details:

An Electrical Motor Centrifugal Switch is a mechanical device used in single-phase induction motors to control the connection and disconnection of the starting winding or starting capacitor. It operates automatically based on the motor’s speed, ensuring efficient startup and reliable performance.

When the motor starts, the centrifugal switch keeps the starting circuit engaged, providing the necessary torque for motor acceleration. As the motor reaches a preset speed (typically around 70–80% of full speed), the switch opens the circuit, disconnecting the starting winding or capacitor to prevent overheating and energy loss.

Key Features:

• Automatically engages and disengages the starting circuit

• Precision-engineered mechanism for accurate speed operation

• Built from high-quality metal and insulating materials for long service life

• Available in various speed and current ratings

• Ensures smooth, efficient motor startup and protection

Applications:
Used in single-phase induction motors found in air compressors, pumps, washing machines, woodworking machinery, and other motor-driven equipment.
