Abstract

See full text

A battery-powered tool includes: a housing, a driven element supported by the housing, an electric motor coupled to the driven element so as to drive the driven element, a battery electrically coupled to the motor so as to supply electric current to the motor and a control circuit arranged to control the supply of electric current to the motor from the battery. The control circuit includes a main switch operable by a user and an auxiliary switch also operable by a user. The control circuit has an active state in which operation of the main switch by the user allows electric current to flow to the motor to cause the driven element to be driven; and an inactive state in which operation of the main switch does not allow electric current to flow to the motor and so the motor does not drive the driven element. Operation of the auxiliary switch causes the control circuit to change between the active and inactive states.
