Abstract
Improvements made to a router a relate to a switchable router brake system. The switchable brake system permits a motor brake to be selectably engaged to operate when the router motor is turned off. When engaged, the motor brake, which comprises a brake resistor being placed electrically across the motor windings, causes the router motor to stop rotating almost immediately. This feature, however, is not always desired; the switchable brake system permits the operator to engage the use of the brake only when desired, thus providing the option to selectively eliminate jerking caused electric brake torque induced in the router when the brake engages.
