    hello
    i have a remote controlled motorised reversable device (d/c 2 wires) and want to remove the motor use it to control a larger device which runs a reversable motor through a d/c soft start with a 3 wire (common and 2 lives)
    is there such a thing as a 2 way relay that changes with the coil when the polarity changes on the coil (kind of like a 2 way coil idea)

    please help

    If it is DC with 2 live wires, why would you need to switch the common? Can you attach a schematic?

    the larger device ran using a on of on wall switch which was voltless to control the direction on the soft start but the remote controlled device doesnt have enough amps to control the larger device therefor i need to be able to control the common and forward or common and reverse on the soft start using the remote with polarity reversing 2 wire that used to be attatched to the motor of the small device

    You didn't mention what your control voltage is, but if it's 12v, you could use some (relatively) inexpensive automotive SPDT relays and a few 1A diodes like this:
