Here i am uploading responses for different conditions.

1)Both switches are open.

Oscilloscope-XSC1 х Channel_B Reverse T2 Time 0.000 s 0.000 s 0.000 s Channel_A 0.000 V 0.000 V 0.000 V T2-T1 Timebase Scale: 10 ms/Div X pos. (Div): 0 Y Add B/A A/B Channel A Scale: 5 V/Div Y pos. (Div): 0 Channel B Scale: 5 V/Div Y pos. (Div): 0 AC 0 DC Save Ext. trigger Trigger Edge: FE AB Ext Level: 0 V O Single Normal Auto None AC 0 DC

2)When Switch A is Close and B is open(FORWARD Direction)

Oscilloscope-XSC1 Channel_B T1 T2 Reverse Time 0.000 S 0.000 s 0.000 S Channel_A 0.000 V 0.000 V 0.000 V T2-T1 Timebase Scale: 10 ms/Div pos. (Div): 0 Y/Add B/A A/B Channel A Scale: 5 V/Div Y pos. (Div): 0 Channel B Scale: 5 V/Div Y pos. (Div): 0 Save Ext. trigger Trigger Edge: FZ A B Ext Level: 0 V Single Normal Auto None AC 0 DC AC 0 DC

3) When switch B is close and A is open(REVERSE Direction)

Oscilloscope-XSC1 Channel_B Reverse T2 Time 0.000 s 0.000 s 0.000 s Channel A 0.000 V 0.000 V 0.000 V T2-T1 Timebase Scale: 10 ms/Div pos. (Div): 0 Y Add B/A A/B Channel A Scale: 5 V/Div Y pos. (Div): 0 Channel B Scale: 5 V/Div Y pos. (Div): 0 Save Ext. trigger Trigger Edge: FZ A B Ext Level: 0 V O Single Normal Auto None AC 0 DC AC 0 DC

Here i have uploaded ckt diagram and responses.

In responses 2 & 3 at first switches were open. so response in first division is at 0. Then when switch is closed, we can see the curve changing w.r.t. Direction.

If you have any doubt, let me know.
