Develop a simple stop/start relay control circuit for a three phase motor with forward/reverse.

use the following devices with labels:

Start pushbutton(N/O) -PB1
Stop pushbutton(N/C) -PB2
Emergency stop(N/C) -ES1
Motor overload(N/C) -OL1
Forward switch(N/O) SS101
Reverse switch (N/O) SS102
Relay 1 R1
Main contactor K1M
Forward contactor K2M
Reverse contactor K3M

the forward/reverse switch (SS) is a selector switch with only one switch setting at any time.
