    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.
