Spark-proof switch
EUGS students at the spark-proof switch project
Tenth grade students, Hasna Hena Mou and Jinia Akter Arianna, of the Engineering University Girls School (EUGS) have designed a 'spark proof electric switch.' The `spark-proof switch' they designed can be used both for AC and DC power lines. This switch is safer than the usual electric switches available in the market. Mercury has been used to make the switch more convenient to design. The main part of the switch, which resembles a tube, is coated in glass as insulator. The positive and negatives poles of the switch remain within the glass coating. Any spark created is absorbed by the Mercury. The 'spark-proof switch' project won the 3rd place at a Science Fair held on the BUET premises.
