Abstract

1290770 Control of D.C. motors SKIL (NEDERLAND) NV 17 Aug 1970 [19 Sept 1969] 39564/70 Heading H2J [Also in Division H1] A switch unit for controlling a portable powertool comprises a trigger operating a first contact assembly for starting and speed control of the tool and a push pull member 19 operating a second contact assembly 46-50 for reversing the motor of the tool, the contact assemblies and circuit elements for the motor control being carried on a single mounting board (Division H1). The contact assembly 40 has an initial position in which the motor is off, a final position, bridging contacts 52, 54, in which the motor is directly connected to the supply and intermediate positions in which the motor is supplied through a thyristor 63 whose conduction is varied by a varible resistance 58 coupled to the trigger contacts 40.
