vintage deco ironstone architectural surface switches, never used

Lot of two matching architectural china light switches. The housings are made of white ironstone porcelain and are marked P. P. Inc. The switches are single pole. These switches are made for surface mounting directly to the wall or door frame.

They measure 5" long, 1 3/4" wide (side to side) and about 2 1/4" thick. There is also the remains of the original installation wiring instruction sheet.

These are from the estate of a man who worked architectural restoration and salvage for many years.
