The invention relates to a diverter switch which is intended to be part of an on-load tap changer for transformers. The diverter switch is provided with main contacts (10-13), arcing contacts (14-17) and resistor contacts (18-20). The movable parts (11-13, 15, 17) of the main and arcing contacts are arranged on a contact carrier (35) which is rotatable back and forth and operated by a central axle (34). In addition, the contact carrier is provided with one arm (19) per phase which, in addition to operating the resistor contacts (18-20), also constitutes one of the contact members thereof. The correct contact sequence when switching between different winding terminals is achieved by the location of contacts (10-20) and stop members (38, 39, 43). |
