Earthing switch EMD6is our new product, it outside shape and technical parameters perfectly match EK6. Working Principle When operate driving mechanism to close earthing switch, applied moment gets principle axis to overcome drag torque, to spur console panel to turn under the closing direction, and gets moving contacts rocker to via spring dead point, and then spring will release energy, to close earthing switch quickly. In closing position, moving contact firmly connected with fixed contacts flange part. When openning, applied moment gets principle axis to overcome drag torgue and spring power, spur console panel to turn under the opening direction, and gets moving contacts rocker to compress spring to dead point, and then spring energy storing is over, prepare for the next closing.
