- Polarity reversal capability: The switch provides reversal of electrical polarity for reversible motor operation. Because it uses mechanical internals, performance can degrade over time and the unit may eventually need replacement. - All-in-one control: One switch handles both on/off and variable speed functions, simplifying tool control and reducing the number of components. - Electrical braking: The switch supports electrical braking, helping the tool stop quickly for improved safety and workflow. - Replacement part for power tools: Commonly used to replace worn or failed switches in electric power tools, helping restore original control performance. - Use scenarios: - Reversible drilling or driving: switch direction as needed for screws or back-out operations without changing components. - Variable-speed work: adjust speed for different materials or tasks (wood, plastic, metal) using a single control. - Quick stop and safety: employ braking to halt the tool promptly between operations.
