Abstract
The present invention is relative to a water-immersed switch which does not conduct electricity in the absence of a dielectric liquid, such as water, and which conducts electricity in the presence of the dielectric liquid. The water-immersed switch includes a modified copolymer containing acrylonitrile and at least one of styrene and/or a conjugated diene, as constituent units, and acidic groups introduced into said modified copolymer, and a plurality of electrically conductive electrodes.
