    hi all
    i have been given a ckt to minimize the components required. i am attaching the ckt as pdf.

    the ckt is for operating a small dc motor. when sw1 is pressed it starts moving in left direction. after reaching the extreme left position, we get indication through No/NC contacts. the motor cannot be stopped in between. when in left position then only switch 2 will work.

    i cannot use digital pulse based h-bridge or microcontroller. also another switch might be required to stop the motor in between and then change the direction.

    thanks in advance
