Start switch is a Push button - so it's normally in open condition
so the voltage across the 1-CR1 is 120V
the stop switch is normally closed button when we press the switch then only it will acts as an open circuit until it's acts as an short circuit so the voltage across the stop switch is 0V
when on 1-CR1 terminals was short circuited by the start button so the voltage across the 1-CR1 is 0V entire voltage appeared across CR1 only
| OFF | During ON | |
| voltage across 1-CR1 | 120 | 0 |
| voltage across STOP button | 0 | 0 |
| voltage across CR1 | 0 | 120 |
at the time of off only the voltage across STOP button is 120 V in remaining all the cases is 0V
