Subject: Question for today

In our schematic diagram at bottom I’ve always wondered about the representation of the key.  Notice there is a circular object in the box, just above the key symbol. Could this be like the one shown on the top photo, right hand side?  Do you have one like this in your museum?  I could use detailed photos if you have one there.  My guess is the cylindrical object is an interrupter in case DC power is used.  In this case I’d need to make a smaller key like at right instead of the large pump handle and figure out how to make the interrupter. Lots of work there, might be for a later time. 

Thanks;
Dick Tormet
