Abstract
An electrical tool, in particular drill and chiselling hammer, including a drive shaft and two driven members. The drive shaft is operatively connectable with the driven members by a respective one of a pair of coupling sleeves. The coupling sleeves are actuatable by a rotatable and mechanical actuating element, in particular a mechanical rotary switch. The actuating element of the electrical tool includes transmission features or a transmission portion that is stationary with respect to the actuating element and which is contactable directly with the respective coupling sleeve for actuating the coupling sleeves.
