Abstract
An electric tool rheostatic device in a switching arrangement is provided for regulating the speed of an electric motor in an electric tool. A circuit board for receiving electronic components is disposed in a switch housing. A potentiometer disposed within the switch housing includes a potentiometer slider operatively connected with a manually-operated actuating member and a resistance track that is constituted by a chip resistance element produced independently of the circuit board according to surface mounted device technology and mounted on the circuit board independently of the potentiometer slider. Upon assembly of the switching arrangement the potentiometer slide is adjustably located on the resistance track by the manually-operated actuating member for controlling resistance.
