|The American Flyer 720 remote switch was produced from 1946 to 1949. The 720a was introduced in 1949. It was produced till 1956. The switches differed in base, motor and lamp cover. There was a V notch in the base between the straight rails and the curved rails just in front of the 2 train button, there was a long motor housing in back of the binding posts, and the lamp cover was round from side to side, and that square area was more shallow as the motor was not under the lamp assembly.|
Because of internal differences, make sure you have the correct control lever before you connect them to power.
The 720 switches had 'non-self centering' control levers.
