The four constituent parts of the switch from the back appear in the lower left hand corner of the photo below. These are retained on the back with two #8-32 x 3/4" slotted flat head machine screws.
As Terry indicates, you are also missing the small, hollow threaded plug in the center of the left side along with the small steel ball and spring that fit in the hole. Those three items were used on all '32-'36s (at least) and replacements are available at fordbolts.com (Roy Nacewicz).
The plastic ignition switch plate with the wire terminals shown in the photo is unique to '32s, but the service replacement used at least through the '36 models is stronger and a lot easier to find (at least one is listed on eBay at the present time). The other three relevant parts in the photo are also common with those used on '33-'36s (at least).
It appears that the hole in the upper left corner that has been threaded has also been enlarged in the process. Compare it to that on the left in the second photo which is NOS.
