Abstract
A variable resistor (44) and conductors (36,38,42,46) for the speed control circuit are printed on a flexible insulating film (28) held against a flat heat sink (24) in an upright plane by a deflected conductive tab (34) protruding within an aperture (30) in the film pressed over the anode of a thyristor (26) soldered to the heat sink (24). The resistance (44) and collector (46) elements of the variable resistor are formed on a flap (32) which is folded over in a horizontal plane to present uniformly disposed surfaces for engagement by a trigger-carried wiping contactor (54). A chip capacitor (48) is soldered to conductive segments (36,38) of the printed circuit.
