I believe the proper name is a Douglas connector but more commonly are called bullet connectors. They are still used in many modern applications and come in several sizes. Packard for the most part used the .156 diameter size.
The pins fit into a keyed two part plug with one side being a permanent part of the main loom. The pins pull out of the other side so the switch can be changed but must confess I do not remember how the pins are retained.
The photo shows part of the plug. Note that unless your car has factory AC the fuseblock will be on the firewall and completely out of the way so the plug will be easy to reach. AC cars suspended the fuses in the underdash location because the evaporator box takes up almost the entire firewall.
Here is an extracted part of the wiring diagram showing the plug and brake light/turn signal circuit as it passes thru the switch. The photo is of a 49-54 switch. 55-6 is the same electrically but is of different construction and looks. There is also one extra wire in the center of the 55-6 plug which is for the horn. Website no longer allows most photos to be expanded so can't enlarge your photo to get a better view. I think I see an extra wire with a ring terminal near the switch so that is probably the horn wire which would go on the contact ring clamped around the center insulator piece.
