Abstract (en)
[origin: EP2524775A2] A power tool includes a motor, a light unit, and a switch unit for selectively connecting the motor and the light unit to the power source. A control module includes a controller coupled to a first electronic switch to control power delivery to the motor based on a position of the switch unit, and coupled to a second electronic switch to control power delivery to the light source based on a position of the switch unit. The controller also includes a timer configured to keep the light unit illuminated for a predetermined amount of time after the switch unit has been activated or deactivated. The control module also includes a boot circuit connected to the controller. The boot circuit includes a semiconductor switch configured to continue to deliver power to the controller and to the light unit when the switch unit is deactivated subsequent to being activated, to enable the light unit to remain illuminated after the switch unit has been deactivated.
