Switch Assembly 23-66-3020

A cordless ratchet that will not start or cuts out during use may have a worn switch assembly. The unit combines the trigger switch, control electronics, and battery connection to manage motor operation and variable speed. First test with a known-good battery and inspect the terminals, motor, and internal wiring. Match the replacement to the full tool model because similar assemblies may use different connectors. Remove the battery before service, keep small parts organized, and route each wire through its original guide. Test the trigger only after the housing is fully secured.
