Abstract
Improvements made to a router include a switching system which is part of a router handle and which operates the router motor by connecting it to an external electrical power source. In a preferred embodiment, the present switching system comprises the use of a locking lever and trigger in combination to activate the motor, to hold the trigger in a locked-on position to maintain the connection of electrical power to the motor, and to lock the movement of the trigger from occurring before an operator attempts to engage the motor. The switching system may also be combined with a preferred router handle shape in order to make the long term operation of the router and its switching comfortable with extended use.
