Abstract
A safety device includes a trigger for activating a first switch and a brake device for braking the output shaft of the electric tool. The trigger is controlled by a safety button that pivots a pivotal member that is engaged with a rotatable member when an intermediate member of the brake device is shifted by operating the brake device. The rotatable member matched with the pivotal member is rotated to activate a second switch. The electric power is provided to the output shaft when both the first and second switches are activated.
