Control Circuit diagram for starting and stopping a motor with 2 N.O momentary switches

So normally when controlling a dc motor with 2 momentary switches , you use NC for stop and NO latched with a relay start. right ?

the instructor wants us to design the control circuit for 12v dc motor with 2 NO momentary switches (one for start and one for stop ) ?

another assignment is control circuit a motor with 2 NC momentary switches ( (one for start and one for stop ) ?

please can you help me with some wiring diagram or insructions of how to connect each switch to a relay.

Thanks a lot

Google on how to make a relay latch itself. That should get you some ideas. Post YOUR attempt at the circuit and we will critique it. We will not do your homework for you.
