INGCO S-ER-VSSW-RT16008, Electric Router-Variable Switch(S-ER-VSSW-RT16008)

product details:

In an electric router, the variable speed switch is a crucial component that allows you to control the speed of the rotating bit. This fine-tuned control is essential for achieving clean and precise cuts in various materials like wood, plastic, and laminates. Here’s a detailed breakdown of the variable switch and its functionalities:

Components:

1. Control Knob/Dial: The most visible part of the variable switch is the control knob or dial. This is the user interface where you adjust the desired speed setting. It can be a simple rotary dial, a lever-operated switch, or a more advanced digital control panel depending on the router model.

2. Electronic Circuitry (Most Common): Modern routers primarily use electronic circuitry to regulate motor speed. This circuitry often includes:

   • Variable Resistor: This component controls the amount of electrical resistance in the circuit. By turning the control knob, you adjust the resistance, which in turn affects the voltage reaching the motor.
   • Pulse Width Modulation (PWM) Control (In some models): This advanced technique regulates the speed by varying the on-off cycles of the power delivered to the motor. This allows for smoother and more precise speed control.

3. Motor Connection: The variable switch circuit connects to the router’s motor. The adjusted voltage or pulse-width modulated signal from the circuitry dictates the speed at which the motor operates.

Function:

1. Speed Adjustment: As you rotate the control knob or adjust the lever/digital control, the variable resistor or PWM circuit modifies the electrical signal sent to the motor. Reducing resistance or increasing the pulse width allows more current to flow to the motor, resulting in a higher speed. Conversely, increasing resistance or decreasing the pulse width limits the current, leading to a slower speed.

2. Matching Speed to Material and Application: The variable switch empowers you to select the optimal speed for the material you’re working with and the specific cutting task. For instance, delicate materials like veneer might require a slower speed to prevent burning or chipping, while harder materials like hardwoods might benefit from a higher speed for efficient cutting.

3. Safety and Control: The variable speed switch enhances safety by allowing you to begin cuts at a slower speed for better control and then gradually increase to the desired cutting speed. This helps to minimize accidental tool movements and ensures cleaner cut finishes.
