Cordless drill in need of repair (Ringwood BH24)

Mac Allister Cordless Drill, no drill bits included.

The battery charges, but the trigger switch gets stuck when you press it in, meaning the drill will not function. However, lights on the battery when you press the trigger suggest to me that it is a mechanical issue

Might be a simple fix for someone who knows how?

This drill has been sitting around for a number of years…
