Hello, the circuit is a bit complicated but it's OK, it works. The Start/Stop function is done by two pushbuttons. This can also be done with a relay with a self-holding contact and a working contact. For an electronic switch with a single button try this

I like your idea Clean stable voltage. The control voltage in the non-inverting inputs can also be 5V, the output voltage is still 28.5 V because in EC the operational amplifiers are ideal and have a supply of +/- 15V from the ground (and you can't control it externally) - at least that's what I think :)
