    Hello all!

    I am in the middle of a project and I am a bit stuck in this portion of it :

    I have two momentary switches with one of them (call it s1) attached to a relay and on the other side of the relay a motor and battery. The operation I would want the motor to have would be this :
    When s1 is pressed and held down the motor spins. It spins until either s1 is released OR s2 is triggered but not held down. In order for the motor to spin again, s1 would have to be released and triggered again. So essentially, s2 would "cut off" power despite s1 being held down until s1 is pressed again.

    I know it could be done with relative ease with a microcontroller, but I want it to be as simple as possible.

    Thank you all in advance!

    Something like this might work.
