Abstract
An electronically controlled add-on device with a switch arrangement comprises a powered switch which is open during most of its lifetime, i.e. during both storage and operational use. More specifically, in one embodiment the add-on device comprises a secondary switch so that there are an open and a closed switch. The logics of the electronic circuitry control the circuitry so that the closed switch will be un-powered and the open switch will be powered. When the switch is mechanically changed, both switches are changed by the controller so that the closed switch will be un-powered and the open switch will be powered.
