I really like what you did here and showing the breadboarding in detail. Most if not all JFETs have symmetrical source/drain so you might want to show they are interchangeable.
If you mean apply voltage to turn it off, if it's on or turn it on, if it's off, you could put a latch in front of the gate and wire it to toggle. Lots of info online about that. A JK or T latch would be the simplest to use. Flip flops are more complex but more useful in general.
Thank You, well explained

How could you make toggle switch as a transistor. switch to on off Jfet.
