Thank you.

The simplest approach would be to have the switches activate a "latching relay" with DPDT contacts to reverse polarity of the power applied to the motor. You can purchase latching relays that rely on permanent magnets or mechanical latches in the relay or you can create your own by using a plain relay with a third contact to hold the relay closed. Circuit details are simple but would vary depending upon the type of relay and configuration of actuation contacts you employ.
