Abstract (en)

[origin: WO9734311A1] The proposed switching device has the advantageous features of semiconductor switching elements (1) while at the same time meeting the requirement for a visible isolating distance (4). This is done by incorporating the semiconductor switching elements (1) in a moving switching element (2) which creates the isolating distance.
