Abstract

Improvements made to a router relate to ergonomic router handles. The preferred router handles are generally elliptical in shape and have one end narrower than the other end. The handles are shaped to provide an operator an infinite number of angles to which the operator's hand may effectively grip the handles. Additionally the handles provide an outer surface which provides a flat tactile grip area. The combination of these elements, along with the shape and location of the preferred trigger and locking arm switch used to activate the preferred router, provides an operator, while operating the router, with the ability to find and use a handle-holding position which is comfortable for the individual user for holding the handles.
