Abstract
The present invention is directed to a power tool including a wireless remote stop for terminating the flow of electricity to an electric motor. The electric motor is configured for operating a working element assembly of a power tool, such as an arbor/circular saw blade included a table saw. In an embodiment, a remote stop is a hand-held fob, having a housing and a button. Alternatively, the remote stop may be implemented as a foot pedal apparatus, for being disposed on a shop floor.
