I dont think the 33 had a hand pushed button to crank that is done by a foot operated button/pedal just forward of the gear shift lever (another anti theft device). Your ignition switch should work with battery hot wire to bat and coil to ign with key in the run position. I am not sure when some models had the starter operated by the accelerator pedal but I think it was several years later.

Your 1933 Master would have originally been equipped with the Starterater which started the car by pressing the accelerater pedal.

If you are using a modern switch with a start position, you will need a wire from the start terminal, on the switch, to a small terminal on the relay/solenoid. This energizes the relay when you hold the key in the start position. Some relays have more than one small terminal. I suspect that yours has only one, if it has the pushbutton built in. These were usually seen on tractors. Make sure the relay is made for the voltage of the car. If the relay is for a 6 volt Ford tractor, it might make a difference that the tractor was positive ground.

There are dozens of versions of these relays that look pretty much alike, but are wired different. Some ground to energize, some use a hot wire to energize, some ground through the base, some do not.
