Description
Overview
Trigger-style speed control switch for cordless drills, electric wrenches and screwdrivers. It combines motor start/stop, stepless speed regulation and forward/reverse switching in one unit. Supplied in a range of CR-620 models to match different brushed and brushless tool platforms.
Specifications
- Working voltage: DC 7.2–24V (models also rated to 42V / 60V)
- Rated current: 16A
- Functions: start/stop, stepless speed control, forward/reverse direction change
- Motor compatibility: brushed models pair with brushed motors; brushless models pair with brushless motors
- Available models: CR-620A through CR-620R (24 variants — match your original switch)
- Feature: dustproof construction
Purpose
The trigger switch is the part that fails first on a cordless drill: the contacts burn from repeated arcing and the speed control becomes erratic or dead. Replacing just the switch restores full control at a fraction of a new tool, provided the model and motor type match.
Applications
- Cordless drills, drivers and impact drills
- Electric wrenches and screwdrivers
- Power tool repair and refurbishment
- Brushless tool platforms (with a brushless-matched model)
How to Use
- Open the tool and read the model code on the original switch — the CR-620 variants are not interchangeable.
- Confirm whether the tool uses a brushed or brushless motor; fitting the wrong type will not work.
- Disconnect the battery before starting and photograph the wiring before removing the old switch.
- Transfer the leads one at a time to the matching terminals on the new switch.
- Test direction and speed control with the tool unloaded before reassembling.
