ABSTRACT:
The switch includes a mounting plate supporting two high voltage RF contacts in spaced relation with each other and with the mounting plate. A shorting bar is provided between the mounting plate and the two contacts in a switching relation with the two contacts. The shorting bar is actuated by a first pneumatic actuating arrangement supported by the mounting plate to make and break a connection between the shorting bar and both of the contacts. A grounding arrangement actuated by a second pneumatic actuating arrangement grounds one of the two contacts when no connection exists between the shorting bar and both of the contacts and ungrounds the one of the two contacts when a connection exists between the shorting bar and both of the contacts.
