摘要

The switch (75) for the tool release detection device has a free end (75A) acting as a contact, located inside a curved body (3) housing the drive part (5) of the tool (1). The tool has a pivotable drive part mounted inside an elongated curved body, the pivoting action being generated by a pre- determined release torque. The tool release detection device comprises an electric circuit with a switch actuated by the drive part. A processor (79) is designed to utilise information provided by the state of the switch.
