- Reversible polarity capability for compatible motors: The switch uses mechanical internal components to reverse electrical polarity, enabling direction control. Over time the internal parts can wear, and replacement restores reliable operation. - All-in-one on/off and variable speed control: One switch handles both power and variable speed functions, simplifying operation and wiring. - Supports electrical braking: The switch is involved in the tool’s braking function where applicable, contributing to safer and quicker stops. - Common replacement part for power tools: Switches are a typical wear item in portable tools and are replaced to maintain performance and reliability. - Durable construction and reliable performance: Designed with robust internal mechanisms to withstand regular use and service. Practical use scenarios - Replacing a worn switch in a portable drill to restore direction control and speed adjustment. - Restoring control in a grinder or jigsaw that requires smooth on/off and variable speed operation. - Servicing a tool with braking functionality to ensure quick and reliable stopping.
