Abstract

A handheld work apparatus has an electric motor for driving a tool. A function module is to be connected to a battery pack via electrical contacts, there being provided an electrical operating switch, for putting the electric motor into operation, which is coupled to an actuating element of the handheld work apparatus. The electric motor is put into operation upon a command of the operating switch, via a control unit. To constitute the function module, provision is made to dispose the electrical contacts, the control unit and the operating switch on a common carrier. The carrier has a first side that faces toward the battery pack, and at least one second side that faces away from the battery pack. The electrical contacts are provided on the first side of the carrier, while the operating switch is held on the second side of the carrier.
