The invention relates to a rotor blade, preferably for use in a wind turbine, comprising a rotor wing. Thyristors are used as high side switches, and arranged to self-latch. The client application may transmit the order to a proxy module. The method further includes grafting onto a domain root of the domain manager service the received exported sub-domain roots. The second dielectric film includes therein a zinc sulfide at a rate of 10 to 40 mol % and a tantalum oxide at a rate of 20 to 50 mol %, for preventing sulfuration of Ag in the reflecting film.
