I haven't looked at mine lately, but the lever that shuts off the phono motor should have two parts, like sort of a fork. The trip in oin the pickup arm should be in between those two spring-loaded levers. When the pickup gets to the end of the record, and goes into the ecentric trip groove, any motion backward (toward the outside of the record) will trip the switch, and turn off the motor. Some turntable switches also have a friction brake on them to stop the turntable.
