First, some clarity. A "pushbutton" almost always *is* a mechanical switch.I need to use a simple pushbutton, not a switch o mechanical push button.
Not only is it a 2-MOSFET version of the circuit in post #7, it is also a two-MOSFET version of the two-inverter circuit! (Post #13)Here's a two MOSFET version of the circuit in post #7:
They both have the advantage of using no ICs and not requiring an added transistor to drive the LEDs.
MOSFET M2 just needs to be sized to carry the total LED current.
If the supply voltage is less than 10V then M2 should be a logic-level type [Vgs(th) max ≤2v].

Yes, it basically is.Not only is it a 2-MOSFET version of the circuit in post #7, it is also a two-MOSFET version of the two-inverter circuit! (Post #13)
