Abstract (en)

[origin: EP0468272A2] An electrical switching device has a detachable latching device, comprising a plurality of elements, for opening or closing the electrical contact system. According to the invention, at least one element (1) of the latching device extends directly or by means of a hinged additional element into a closed container (2). The latter is filled with an electroviscous fluid (3), whose viscosity is influenced by electrodes (4a, 4b) generating an electric field. The two examples show a switching mechanism, having electronic latching, and a bounce suppressor. <IMAGE>
