What is the momentary switch for? The one on the right side of the diagram connected with green wires.
Most latching relays that I am aware of only need the coil voltage applies for a short time. Is this the way your latching relay is susposed to work?

hi thanks for yor reply,
i think its called a momentry switch its one that dosnt latch.
Yes the momentry switch makes a circiut through the normarly closed and common of the first micro switch, which is pressed in so it is now open making the motor stop.

Remove the black lines on your latching relay.
