My dad gave me a Model Machine Works (Glendale, CA) power hacksaw and I am in the process of cleaning it up.
The saw has a clyndrical power switch (about 3" dia x 2.5" tall) with two vertical buttons (on & off). When the saw finish its cut, a lever on the saw arm pushes the black OFF button and the saw turns off.
The switch is maked 1/4HP 125V and the logo of CH. I presume this means Cutler and Hammer. I have searched Cutler and Hammer's web site listings of vintage switches but none like this shows up.
Picture of switch:
