Abstract

1354524 Control of A.C. motors HEINRICH KOPP 19 April 1971 [18 March 1970] 20300/71 Heading H2J [Also in Division H1] The invention relates to a trigger switch (Division H1) for a power tool which has a locking push button for holding the trigger in the onposition, the button also being rotatable to vary the setting of a speed control circuit. The trigger switch closes contact 3 to energize the universal motor 11 through a thyristor 12. The locking button 4 rotates a potentiometer 13 to adjust the phase angle at which thyristor 12 is fired by diac 15 and diode 16. In the maximum speed position of the button a cam closes a further contact 18 to apply full A.C. to the motor.
