ABSTRACT:
The invention discloses a switching device for switching signals of very high and ultrahigh frequencies comprising an insulating base, a plurality of stationary contacts, a sliding contact, and shielding means for isolating between the adjacent stationary contacts. The shielding means is electrically connected to a metal housing so that signal leakage due to the electrostatic and electromagnetic coupling may be prevented.
