One Button On Off Switch with 4093 and IRFZ44

The load is driven by the MOSFET IRFZ44 and 4093 AND gates are used in the circuit. The output of the 4093 IC drives the MOSFET. Only one button allows you to change the on-off state of the electronic circuits in which you use this switch. The circuit schematics is above. Click image to see the larger schematics diagram.

What could be the benefit of making this circuit with gates? I am interested in building this because it looks more sophisticated than simple push-push button..

4093 is a "NAND" gate (Quad two input NAND gate (Schmidt trigger)) according to Fairchild, not a "AND" gate IC. Is this drawing still correct, and just a misprint on the type of gate used?

thank you very much for the correction :)

what is benfit we can use without circuit to on and off the switch by pusins on and off.

Can this circuit be upgraded to be used with a 24vdc system to drive the solenoids on a pneumatic valve..?

the circuit is very very versatile and can drive a load through relay by adding a transistor at output.
