Mondial ignition switch removal

The ignition switch in my '84 Mondial Cab. has started acting flakey lately. I pulled the plastic steering column covers but can see no way to remove the switch, it's encased in metal and does not appear to be accessable. Can soneone detail how to remove the electrical part of the ignition switch so I can clean the contacts?

Thanks in advance,

Bill
