Abstract

An apparatus for providing convenient control of a power tool electrical system. A switch assembly includes a first actuator and a second actuator, which is disposed remotely from the switch and first actuator. The second actuator is connected via a coupling device, such that user manipulation of either the first or second actuator is capable of controlling electricity flowing to the motor. Including a second actuator may permit the user to retain greater control over the tool when turning the power on or off. In additional exemplary aspects, a coupling device included in the switch assembly is configured and arranged so as to prevent inadvertent damage to the power tool such as by accidental engagement of a shaft lock while the motor is operating.
