Description
Overview
A miniature trigger switch for electric hand tools, the part in the grip that is pulled to start the motor. The lever carries the speed control, so travel past the first click raises the motor gradually rather than slamming to full.
Specifications
- Function: trigger with integrated speed control
- Build: miniature, for compact grips
- Models: CR-623A to CR-623S, 19 variants
- Host tools: electric hammer, impact drill, polisher, cutting machine
Purpose
When a trigger dies the tool is usually still sound, and the switch is the cheapest part left to blame. The A-to-S numbering covers the differing trigger pockets of drills, hammers and polishers.
Applications
- Impact drill trigger replacement
- Rotary hammer rebuild after a failed switch
- Polisher trigger repairs
- Cut-off machine handle switches
How to Use
- Unplug the tool or pull the battery before opening the housing.
- Match the old switch to the CR-623 code by lever length and screw positions.
- Photograph the wiring, then move each conductor to the same terminal.
- Seat the switch and check the lever clears the shell.
- Caution: no voltage or current figure is stated, so match the rating of the switch being removed.
