Maybe a JK latch? Need some help

Question

complete electronics novice here unfortunately. Please bear with me.

I'm after some kind of switch (latch/flip-flop?) that will interrupt a momentary switch held in its 'on' position when another momentary 'reset' switch is pressed but also requires the 'on' switch to be released and then pressed again before triggering. This is to control a motor that is currently driven by a mosfet circuit so I'm just after a logic level signal to feed into it.

e.g 'on' switch held -> motor starts -> 'reset' button pressed whilst 'on' switch still held -> motor stops -> 'on' switch still held -> motor still stopped -> 'on' switch released and then held again -> motor starts

I apologise in advance for the total lack of terminology. If I can just get pointed in the general direction of something it would be greatly appreciated.

Answer 1

If you want to use relays, this should work: -

So when you press start and hold it, the supply is routed to the motor via the relay NC contact and the motor spins. If whilst holding the start button the reset button gets pressed momentarily, the relay latches the "reset event" because the relay contact then shorts out the reset button. And, at that very instant, the motor is disconnected from the supply.

Not until the start button is released can the relay/latch be unlatched and then, the whole cycle is back to the beginning.

Answer 2

This will do what you have asked for, assuming it is OK to use logic ICs. This can alternately be implemented using relays. Let me know if you need that instead.
