Abstract
The invention relates to an accessory () for connection to an electrical interface () of a portable electronic device (), which interface comprises a pair of bias voltage providing connection points including a first connection point () and a second connection point () for biasing a signal providing element () that may be provided in the accessory. The accessory includes a first electrical branch comprising a first voltage dividing element (R) and a first switch () that can be actuated mechanically. The branch has a first end to be connected to one connection point () in the pair and a second end to be connected to another connection point () for changing the voltage level of the connection point connected to the first end to a certain voltage level when the first switch interconnects the first voltage dividing element and this connection point.
