Abstract (en)
[origin: EP0512316A2] A switch is proposed, especially for use for a hand-operated battery electrical tool having a DC motor, in which control electronics are provided for varying the rotation speed of the DC motor. In order to produce the switch as compactly as possible and without additional lead connections to the power transistor, and in order furthermore to have a positive influence on the heat budget within the switch, a contact system (5) and a freewheeling diode (8) are articulated on a common bearing plate (11) which is connected in a current and heat conducting manner via a connecting bolt (12) to a power transistor (7) on the housing. At the same time, the power transistor is cooled by means of a heat sink which is provided on the switch housing. <IMAGE>
