The listed price is for 1 switch    But showing I have many avialble.   Not sure how old these are . Meant for the wall or machine that uses the conduit twisted type.   Not sure if the old and new conuit are the same size and twist pattern. But most likely sit securely in the space of the light switch.      New old stock. I acquired these about 20 years ago from an antique estate that dealt with old lighting.  I have 4 avialble and one has chips on the edge as shown  Shipping from London Ontario Canada. Other antique lighting parts being listed as well.    Lots of porcalin    I'm listing 3 in this and the chipped one last in another listing when these sell.
