Switch does not work on a 20v drill model KT300A. This is the 2nd drill I've owned with the same problem.

Possible causes of the switch not working on the Kobalt 20V drill model KT300A include:

1. The direction-of-rotation selector is set to the OFF (center) position, which locks the trigger switch.
2. The tool may have an internal fault and may require servicing by a qualified technician.
3. The battery may be low or not properly connected, preventing the switch from activating the motor.

Always check the selector position and battery first before seeking service.
