Abstract

An electromechanical function unit is for a battery operated, handheld work apparatus that has an operating switch for putting the work apparatus into operation. The operating switch is to be actuated by an actuating element of the work apparatus. The operating switch is connected to a control unit for operating the work apparatus. The control unit includes a circuit board having electronic components, and has a first circuit board side, and a second circuit board side that faces away from the first circuit board side. In order to avoid wiring and to reduce the tolerance chain, provision is made to dispose the operating switch on the second circuit board side. The operating switch is supported statically via a support arrangement, independently of the circuit board. The support arrangement has no mechanical connection to the circuit board, and leads from the second circuit board side to the first circuit board side.
