Zusammenfassung:	A common contact is arranged for connection to one of the two lines of an electric power source; a second common contact is arranged for connection to the field windings of the motor. A pair of contact strips is arranged for respective connection to the sides of a motor armature which is wound for rotation in both directions. A pair of movable contacts is mounted by a respective pair of contact carriers for slidable engagement with the contact strips. A reversing arm actuates a shuttle for connecting a selected one of the contact carriers for movement by the trigger from an "off" position wherein the associated movable contact is in engagement with the first common contact and out of engagement with the second common contact to an "on" position wherein said movable contact is in engagement with the second common contact and out of engagement with the first common contact.
