Angle Grinder

Certain power tools can create a major safety hazard if not shut off properly before plugging them back into AC power. An angle grinder at full starting torque can become a heavy projectile if not secured properly by the operator. This customer wanted to offer a safer product as well as provide enhanced features such as variable speed, thermal overload protection, and the all-important restart prevention.  A compact, variable select switch control was designed that prevents the motor from restarting when there is loss of power without switching the tool off.
