the rectangles are resistors, and the square is the moc3041.
and regarding the zeros - usually in this kind of circuit (with zero crossing circuit) you have a consumer with two connections to the AC power - one ground and one power.
and in this case I have a motor with one power connection and two grounds.
When I connect the power and the first ground it rounds forwards, when I connect the power and the second ground, it rounds backwards. In my case, I need to switch between the grounds while the power connection is permanently connected to AC.
For one motor I have got two such a circuits, everyone of them is connected to one Ground. the first circuit connected to GND1 and the second circuit connected to GND2.
when I send dc to moc3041, it opens the gate of the triac that is placed after the moc3041.
but the gate stays open while it gets Alternating Current, but in my solution, I control between grounds, that's why I think the gate won't stay opened (the motor won't spin).
